Each matches a different invitation format, and each has different postage implications.<\/p>\n<h3>A7 &#8211; 5.25&#8243; x 7.25&#8243; (the default)<\/h3>\n<p>A7 is the most common wedding envelope in the US, designed to fit a 5&#8243; x 7&#8243; card with a clean quarter-inch clearance on each side. Your invitation card slides in and out without bunching. A7 mails at the standard USPS First-Class letter rate &#8211; $0.78 as of 2026 for suites up to 1 oz &#8211; and is handled by standard letter-sorting machinery, which means no additional surcharges simply for the envelope shape. Most Australian and US wedding stationery designers default to this format for good reason: it is predictable, affordable, and universally accepted at the post office.<\/p>\n<h3>A9 &#8211; 5.75&#8243; x 8.75&#8243; (for oversized luxury suites)<\/h3>\n<p>A9 is one step up, used when a luxury suite includes a larger invitation card, multiple enclosures, or an overall taller stack that would be crowded in an A7. Both height and length fall within USPS First-Class letter limits (3.5&#8243;-6.125&#8243; tall, 5&#8243;-11.5&#8243; long), so an A9 mails at the same letter rate as an A7 &#8211; assuming the suite stays under \u00bc&#8221; thick and 3.5 oz. If your suite feels forced inside an A7, A9 is the right call with no postage penalty.<\/p>\n<h3>Square &#8211; 5.5&#8243; x 5.5&#8243; (the modern statement)<\/h3>\n<p>Square envelopes are popular for modern, geometric, and minimalist wedding suites. The trade-off is postage: USPS cannot run square envelopes through standard letter-sorting equipment, so they attract a non-machinable surcharge &#8211; currently $0.49 per piece on top of the First-Class letter rate. Budget at least $1.27 per outer envelope before any weight overages. Suites with a wax seal and multiple enclosures often weigh over 1 oz, pushing the total to $1.56 or more per piece. Square envelopes are worth the surcharge for the right aesthetic &#8211; just budget for it from the start.<\/p>\n<h3>6&#8243; x 9&#8243; &#8211; oversized portrait (for statement cards)<\/h3>\n<p>A 6&#8243; x 9&#8243; envelope accommodates full portrait-format or oversized flat invitation cards that do not fold. At 6&#8243; tall &#8211; just under the USPS letter maximum of 6.125&#8243; &#8211; this size still qualifies as First-Class letter provided the assembled suite remains under \u00bc&#8221; thick and 3.5 oz. Add wax seals, a vellum wrap, or thick letterpress paper and you may cross into the flat-rate category; weigh the complete sealed envelope before assuming letter-rate pricing applies.<\/p>\n<table>\n<thead>\n<tr>\n<th>Envelope<\/th>\n<th>Dimensions<\/th>\n<th>Fits<\/th>\n<th>USPS class<\/th>\n<th>Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>A7<\/td>\n<td>5.25&#8243; x 7.25&#8243;<\/td>\n<td>5&#8243; x 7&#8243; invitation card<\/td>\n<td>First-Class letter<\/td>\n<td>Standard US wedding choice<\/td>\n<\/tr>\n<tr>\n<td>A9<\/td>\n<td>5.75&#8243; x 8.75&#8243;<\/td>\n<td>Larger\/taller luxury suites<\/td>\n<td>First-Class letter<\/td>\n<td>No postage penalty vs. A7<\/td>\n<\/tr>\n<tr>\n<td>Square 5.5&#8243;<\/td>\n<td>5.5&#8243; x 5.5&#8243;<\/td>\n<td>5&#8243; x 5&#8243; square cards<\/td>\n<td>Non-machinable<\/td>\n<td>+$0.49 surcharge always applies<\/td>\n<\/tr>\n<tr>\n<td>6&#8243; x 9&#8243;<\/td>\n<td>6&#8243; x 9&#8243;<\/td>\n<td>Oversized \/ portrait cards<\/td>\n<td>First-Class letter<\/td>\n<td>Verify weight stays under \u00bc&#8221; thick<\/td>\n<\/tr>\n<tr>\n<td>A2 (RSVP)<\/td>\n<td>4.375&#8243; x 5.75&#8243;<\/td>\n<td>4.25&#8243; x 5.5&#8243; RSVP card<\/td>\n<td>First-Class letter<\/td>\n<td>Standard RSVP reply envelope<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Postage rates shown are 2026 USPS First-Class rates ($0.78 per 1-oz letter; $0.49 non-machinable surcharge).

When US designers say &#8220;5&#215;7 wedding invitations,&#8221; they mean the <em>card<\/em> is 5&#8243; x 7&#8243;. The correct matching envelope for that card is called an A7, and it measures 5.25&#8243; x 7.25&#8243;. The &#8220;5&#215;7&#8221; refers to the invitation, not the envelope.<\/p>\n<p>This matters when ordering online. Searching for a &#8220;5&#215;7 envelope&#8221; often returns envelopes that are exactly 5&#8243; wide by 7&#8243; tall &#8211; and those are too small for a 5&#8243; x 7&#8243; card. The envelope needs clearance on all sides to allow clean insertion and closure. Search for &#8220;A7 envelope&#8221; or &#8220;5.25 x 7.25 envelope&#8221; to find the correct size.<\/p>\n<p>At Paperlust, every invitation listed with a 5&#8243; x 7&#8243; card dimension is automatically paired with a free A7 envelope. Envelope upgrades &#8211; colored, textured, or lined &#8211; are applied to the A7 size automatically. No guesswork is needed on your side.<\/p>\n<p>The A7 pairs well with standard RSVP cards too. Most US wedding RSVP cards are 4.25&#8243; x 5.5&#8243;, which fits cleanly inside an A2 envelope (4.375&#8243; x 5.75&#8243;).

The right choice depends on your wedding style, guest count, and how much of your invitation budget you have allocated to addressing.<\/p>\n<table>\n<thead>\n<tr>\n<th>Method<\/th>\n<th>Cost per envelope<\/th>\n<th>Time (at home)<\/th>\n<th>Formality level<\/th>\n<th>Best for<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Professional calligrapher<\/td>\n<td>$3 &#8211; $8+<\/td>\n<td>Outsourced (2-4 week lead time)<\/td>\n<td>Very high<\/td>\n<td>Luxury, black tie, small guest lists<\/td>\n<\/tr>\n<tr>\n<td>Hand-addressing yourself<\/td>\n<td>$0<\/td>\n<td>3-5 min per envelope<\/td>\n<td>High (with neat handwriting)<\/td>\n<td>Intimate weddings, guest count under 80<\/td>\n<\/tr>\n<tr>\n<td>Digital address printing<\/td>\n<td>~$0.20 per envelope<\/td>\n<td>Ordered with suite (no home effort)<\/td>\n<td>High &#8211; medium (script font)<\/td>\n<td>Any guest count; most popular option<\/td>\n<\/tr>\n<tr>\n<td>Printed address labels<\/td>\n<td>$0.10 &#8211; $0.30 per label<\/td>\n<td>1-2 min per envelope to apply<\/td>\n<td>Casual &#8211; modern<\/td>\n<td>Large guest lists, modern\/minimalist style<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The most popular option for US couples right now is digital address printing directly on the envelope. With a calligraphic script font, printed addresses are nearly indistinguishable from handwriting at a glance &#8211; and they eliminate the risk of smudging or miswriting envelope 118 of 140. Paperlust&#8217;s Address Manager lets you import your guest list via Excel spreadsheet and generate addressed envelopes as part of the same production run as your suite.<\/p>\n<h2>Invitation Address Labels: When They&#8217;re OK, When They&#8217;re Not<\/h2>\n<p>Traditional wedding etiquette &#8211; consistent with Emily Post&#8217;s guidance on formal correspondence &#8211; recommends hand-addressing envelopes as a mark of personal care for your guests. A stick-on label is the lowest-formality addressing method available, and for ultra-formal or black-tie weddings, it can undercut the elegance of an otherwise beautifully produced suite.<\/p>\n<p>That said, printed address labels are used successfully at modern weddings every day. The etiquette question is really a style question &#8211; does the label fit the overall aesthetic?<\/p>\n<h3>Address labels work well when:<\/h3>\n<ul>\n<li>Your wedding style is modern, minimalist, or casual<\/li>\n<li>Your guest count is large (150+) and hand-addressing is not practically feasible<\/li>\n<li>You use a high-quality label printed on a laser or inkjet in a clean, elegant font<\/li>\n<li>Labels are applied straight and precisely centered &#8211; a crooked label reads worse than a label itself<\/li>\n<li>The label paper is white on a white envelope, making it nearly invisible<\/li>\n<\/ul>\n<h3>Address labels are a poor fit when:<\/h3>\n<ul>\n<li>Your suite is letterpress, foil-stamped, or luxury-printed (a label introduces a visual incongruity)<\/li>\n<li>Your ceremony is formally traditional &#8211; black tie, cathedral, historic estate<\/li>\n<li>You have already invested in calligraphy envelope liners or wax-seal closures (the mismatch is apparent)<\/li>\n<li>Your envelope is a dark or colored stock where a white label rectangle is visible as a distinct element<\/li>\n<\/ul>\n<p>The practical middle ground most couples land on: digital address printing in a calligraphic script font, produced at the same time as the suite. It reads as &#8220;addressed&#8221; rather than &#8220;labeled,&#8221; photos beautifully for flat-lay shots, and requires zero effort at home.<\/p>\n<h2>Wedding Envelope Boxes: Why and When to Order One<\/h2>\n<p>A wedding envelope box is a structured presentation box &#8211; rigid lift-lid or clamshell format &#8211; designed to hold an invitation suite as a gift or keepsake object. It is not a mailing box; it is used for hand-delivery, as a display piece, or as a physical archive of the suite.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"833\" height=\"1080\" src=\"https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/a-luxury-rigid-lid-invitation-box-open-on-a-white-surface-sh.webp\" alt=\"a luxury rigid-lid invitation box open on a white surface, showing a cream invitation suite with floral liner and wax seal visible inside, photographed from above wedding stationery\" class=\"wp-image-12560\" srcset=\"https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/a-luxury-rigid-lid-invitation-box-open-on-a-white-surface-sh.webp 833w, https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/a-luxury-rigid-lid-invitation-box-open-on-a-white-surface-sh-494x640.webp 494w, https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/a-luxury-rigid-lid-invitation-box-open-on-a-white-surface-sh-768x996.webp 768w\" sizes=\"auto, (max-width: 833px) 100vw, 833px\" \/><\/figure>\n<h3>When a box adds genuine value<\/h3>\n<p><strong>Fragile suites with wax seals.<\/strong> A standard A7 mailing envelope does not protect a wax seal from cracking in transit through USPS sorting equipment. A rigid box does &#8211; and it creates an unboxing experience that amplifies the impact of the suite for guests receiving it by hand.<\/p>\n<p><strong>Luxury or destination weddings.<\/strong> When your invitation suite costs $8-15 per set, a presentation box signals the same level of care from the moment the package is received. Many couples order boxed sets specifically for their wedding party, immediate family, and out-of-town VIPs while mailing standard envelopes to the broader guest list.<\/p>\n<p><strong>Keepsakes for parents or family.<\/strong> A boxed, sealed suite is a complete physical artifact of the wedding &#8211; invitation, enclosures, and liner intact. Some couples order 3-5 boxed sets specifically to give as keepsakes for parents and grandparents, separate from the mailing run entirely.<\/p>\n<h3>When a box is unnecessary<\/h3>\n<p>For a standard mailed suite without wax seals or fragile embellishments, a well-constructed A7 envelope protects the contents adequately. Most couples mailing to 100+ guests use standard envelopes for the full list and reserve boxes for hand-delivered VIP sets only.<\/p>\n<p>Presentation boxes are a custom item rather than a standard catalog product &#8211; contact the Paperlust team to discuss options for your suite.<\/p>\n<h2>Customized Wedding Envelopes: Liners, Return Address, Color<\/h2>\n<p>The envelope is part of the design system, not just a container for the invitation. Three layers of customization are available &#8211; and each can be added without changing your core invitation order.<\/p>\n<h3>Envelope color<\/h3>\n<p>Every Paperlust order includes free white envelopes. Upgrade options include cream, ivory, blush, sage, dusty blue, black, and kraft natural paper. Dark envelopes &#8211; black or navy &#8211; pair particularly well with white-ink or metallic-print invitation designs. Kraft reads as organic and botanical, suiting garden weddings and earthy palettes. Blush and dusty rose work with soft romantic and florals-forward suites.<\/p>\n<h3>Envelope liners<\/h3>\n<p>A liner is a decorative paper insert glued or folded inside the envelope flap, visible the moment a guest opens the envelope. Popular liner styles for 2026 include watercolor botanicals (sage, dusty mauve, warm terracotta), geometric grids for modern suites, color-washed gradients, and printed crest or monogram backflaps. A liner is one of the most cost-effective ways to elevate a standard white outer envelope into something unexpected and memorable. For a full guide to choosing and ordering liners, see our dedicated <a href=\"\/blog\/wedding-envelope-liners\/?utm_source=paperlust&#038;utm_medium=internal_link&#038;utm_campaign=cross_sell\" target=\"_blank\" rel=\"nofollow\">wedding envelope liners guide<\/a>.<\/p>\n<h3>Return address and guest address printing<\/h3>\n<p>Custom return-address printing on the back flap &#8211; using a font that matches your invitation typography &#8211; creates a cohesive, finished look that avoids the rubber-stamp or label approach. Paperlust offers envelope address printing at approximately $0.20 per envelope. For large guest lists, this is consistently more cost-effective than hiring a calligrapher and faster than hand-addressing. Paperlust&#8217;s Address Manager tool imports guest addresses directly from a spreadsheet, so the addressing step is part of the order workflow rather than a separate task at home.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"1080\" src=\"https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/detail-shot-of-a-wedding-envelope-laid-open-showing-a-botani.webp\" alt=\"detail shot of a wedding envelope laid open showing a botanical watercolor liner with sage and dusty rose tones, photographed at an angle on a marble surface wedding stationery\" class=\"wp-image-12561\" srcset=\"https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/detail-shot-of-a-wedding-envelope-laid-open-showing-a-botani.webp 720w, https:\/\/blogcdn.paperlust.co\/blog\/wp-content\/uploads\/2026\/04\/detail-shot-of-a-wedding-envelope-laid-open-showing-a-botani-427x640.webp 427w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><\/figure>\n<h2>The Proper Way to Address a Wedding Invitation Envelope<\/h2>\n<p>The complete etiquette reference &#8211; including addressing conventions for couples with different surnames, same-sex couples, families with children, divorced or widowed parents, and guests with professional titles &#8211; is in our dedicated guide: <a href=\"\/blog\/how-to-address-wedding-invitations\/?utm_source=paperlust&#038;utm_medium=internal_link&#038;utm_campaign=cross_sell\" target=\"_blank\" rel=\"nofollow\">How to Address Wedding Invitations: The Complete US Etiquette Guide<\/a>. Below are the five rules that cover the majority of addressing decisions.<\/p>\n<h3>Five core rules<\/h3>\n<ol>\n<li><strong>Use full formal names on the outer envelope.<\/strong> No nicknames. No abbreviations except Mr., Mrs., Ms., and Dr. Spell out &#8220;Street,&#8221; &#8220;Avenue,&#8221; and &#8220;Court.&#8221;<\/li>\n<li><strong>Spell out &#8220;and&#8221; &#8211; never use an ampersand.<\/strong> &#8220;Mr. John Smith and Ms. Jane Doe&#8221; &#8211; not &#8220;Mr. John Smith &amp; Ms. Jane Doe.&#8221;<\/li>\n<li><strong>List a couple with the same last name on one line.<\/strong> &#8220;Mr. and Mrs. John Smith.&#8221; Couples with different surnames go on two lines: &#8220;Ms. Jane Doe \/ Mr. John Smith.&#8221;<\/li>\n<li><strong>Defer to professional titles.<\/strong> Use &#8220;Dr. Jane Doe&#8221; not &#8220;Ms. Jane Doe.&#8221; When both partners hold the title: &#8220;Drs. Jane and John Smith.&#8221;<\/li>\n<li><strong>Inner envelopes are optional.<\/strong> If you use both, the outer envelope uses full formal names and the inner envelope is more casual &#8211; &#8220;John and Jane&#8221; is acceptable. The inner envelope is never sealed.<\/li>\n<\/ol>\n<h3>Outer vs. inner envelopes<\/h3>\n<p>Traditionally, wedding invitations used two envelopes: a mailing outer and an inner that held the suite itself. The outer was addressed formally, the inner more casually and precisely (listing exactly who is invited, including children&#8217;s names if they are included). Today, most US couples use a single outer envelope and omit the inner entirely. For formal or traditional weddings, the two-envelope approach remains appropriate.<\/p>\n<h2>Wedding Invitation Card Envelope Design Ideas<\/h2>\n<p>The exterior of the envelope is a design surface. These are the approaches that are resonating most strongly with couples ordering in 2026.<\/p>\n<h3>Liner patterns<\/h3>\n<p>Watercolor botanicals remain the leading liner category &#8211; soft sage, warm terracotta, dusty mauve, and champagne-toned florals work across garden, winery, and coastal aesthetics. Geometric grids (gold or navy line patterns) suit modern and architectural venues. Solid color-wash liners in a tonal gradient add depth to darker outer envelopes.<\/p>\n<h3>Wax seal closures<\/h3>\n<p>A wax seal on the back flap is one of the most photographed invitation details. For hand-delivered or courier-shipped suites, wax seals are a beautiful finishing touch with no postage implications. For large postal mailings: use flexible sealing wax rather than brittle wax sticks, apply to a self-seal liner envelope, and hand-cancel at the post office rather than letting pieces run through automated sorters. Hand-canceling is free to request at the counter and significantly reduces seal breakage.<\/p>\n<h3>Monogram backflap<\/h3>\n<p>A custom monogram or crest printed or stamped on the envelope backflap acts as a visual signature for the suite. It reads as an intentional design choice rather than a label or sticker, and photographs well in both flat-lay and in-hand shots.<\/p>\n<h3>Colored outer envelopes<\/h3>\n<p>Black envelopes with white-ink addressing make a striking first impression &#8211; particularly for evening or black-tie celebrations. Kraft paper reads as natural and botanical. Blush and dusty sage pair with soft romantic aesthetics. Color envelopes typically require an envelope upgrade order at the time of placing your invitation suite &#8211; they are not available as a separate-item reorder.<\/p>\n<h2>How Many Extra Wedding Envelopes Should I Order?<\/h2>\n<p>Order 10-15% more envelopes than your confirmed guest count. On a 120-guest mailing, that is 132-138 envelopes.<\/p>\n<p>Four reasons the buffer matters:<\/p>\n<ul>\n<li><strong>Addressing errors:<\/strong> A miswritten house number, a smear from a ballpoint pen, a pressure mark that shows through &#8211; each error needs a fresh envelope. Hand-addressing makes this more likely; digital printing essentially eliminates it.<\/li>\n<li><strong>Last-minute additions:<\/strong> The guest list almost always grows between when you order and when you mail. A buffer means no secondary order with a new minimum quantity.<\/li>\n<li><strong>Shipping damage:<\/strong> Bent corners and moisture exposure during transit affect more envelopes than expected, especially for colored or textured stocks.<\/li>\n<li><strong>Keepsake sets:<\/strong> Some couples keep 3-5 fully addressed and sealed envelopes as part of a keepsake suite for parents or the wedding album.<\/li>\n<\/ul>\n<p>When you order through Paperlust, envelope quantity is calculated automatically based on your invitation card count. If you are hand-addressing or anticipate a larger guest list, mention this during the proof review and the team can adjust quantities.<\/p>\n<h2>Where to Buy Custom Wedding Envelopes in the US<\/h2>\n<p>Custom wedding envelopes are almost always ordered as part of an invitation suite rather than separately. Ordering together guarantees that the envelope dimensions match your card, the colors coordinate with your design, and liner or printing options are applied during production rather than retrofitted afterward.<\/p>\n<p>Paperlust ships complete wedding invitation suites &#8211; with free white envelopes included &#8211; to the US via DHL express. Invitation pricing starts from $2.04 per card for digital print. The same production run includes your envelopes, with upgrade options for color, texture, liners, and custom address printing added at the time of ordering.<\/p>\n<p>The production workflow: you place your order, a professional designer prepares your proof within 1-2 business days, you review and approve (two rounds of revisions included at no extra charge), and your complete suite ships to your US address. DHL express delivery is free on orders over $350 USD.<\/p>\n<p>Browse the full <a href=\"\/browse\/wedding-invitations\/?utm_source=paperlust&#038;utm_medium=internal_link&#038;utm_campaign=cross_sell\" target=\"_blank\" rel=\"nofollow\">Paperlust wedding invitation collection<\/a> to see each design&#8217;s card dimensions, included envelope, and available customization options. Every listing shows envelope upgrade choices alongside the invitation design.<\/p>\n<h2>FAQs: Wedding Envelope Sizes, Boxes, and Addressing<\/h2>\n<h3>What size envelope do I need for a 5&#215;7 wedding invitation?<\/h3>\n<p>You need an A7 envelope, which measures 5.25&#8243; x 7.25&#8243;. The &#8220;5&#215;7&#8221; refers to the card &#8211; the envelope must be slightly larger to allow clean insertion and closure. Searching for a &#8220;5&#215;7 envelope&#8221; often returns undersized results; search specifically for &#8220;A7 envelope&#8221; to find the correct product.<\/p>\n<h3>Are A7 envelopes the same as 5&#215;7 envelopes?<\/h3>\n<p>No. An A7 envelope measures 5.25&#8243; x 7.25&#8243; and is designed to hold a 5&#8243; x 7&#8243; card. A &#8220;5&#215;7 envelope&#8221; would measure exactly 5&#8243; x 7&#8243; &#8211; which is the card size, not the envelope size. Always order A7 envelopes to fit 5&#215;7 invitation cards.<\/p>\n<h3>Is it OK to use printed address labels on wedding invitations?<\/h3>\n<p>It depends on your wedding&#8217;s formality. Traditional etiquette recommends hand-addressing, but labels are widely accepted for modern, casual, and minimalist weddings &#8211; especially with a high-quality print and clean font. For formal or luxury suites, digital address printing (a calligraphic script applied directly to the envelope during production) is a better alternative that reads as addressed rather than labeled.<\/p>\n<h3>Should I order a box for my wedding envelopes?<\/h3>\n<p>Only if you are hand-delivering suites, protecting fragile wax-sealed sets in transit, or creating keepsake presentations for family. For standard postal mailings, a well-constructed envelope is sufficient. Most couples reserve box presentation for VIP hand-delivered sets and mail the broader guest list in standard envelopes.<\/p>\n<h3>How do I customize a wedding envelope?<\/h3>\n<p>Three options are available: (1) envelope color &#8211; choose white, cream, blush, sage, black, kraft, or other colored stocks; (2) envelope liner &#8211; a decorative insert printed on the interior; (3) address printing &#8211; a calligraphic font applied to the front of the envelope for each guest address. All three can be combined and are ordered as add-ons to your invitation suite at Paperlust.<\/p>\n<h3>How much does it cost to mail a wedding invitation?<\/h3>\n<p>A standard rectangular suite weighing 1 oz or less costs $0.78 per piece using a USPS Forever stamp (2026 rate). Suites over 1 oz cost $1.07. Square envelopes add a $0.49 non-machinable surcharge on top of the letter rate. Always weigh a fully assembled, sealed envelope &#8211; including all enclosures &#8211; before buying stamps in bulk. Verify current rates at <a href=\"https:\/\/postalpro.usps.com\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">USPS PostalPro<\/a>.<\/p>\n<h3>What size envelope do I need for an RSVP card?<\/h3>\n<p>Most US RSVP cards are 4.25&#8243; x 5.5&#8243;, which fits inside an A2 envelope (4.375&#8243; x 5.75&#8243;). A2 envelopes mail at the standard First-Class letter rate. If your RSVP card is a different size, match it to the next envelope size up with at least a quarter-inch of clearance on each side. Browse the <a href=\"\/browse\/wedding-invitations\/?utm_source=paperlust&#038;utm_medium=internal_link&#038;utm_campaign=cross_sell\" target=\"_blank\" rel=\"nofollow\">full invitation collection<\/a> to see RSVP card and envelope dimensions for each suite.<\/p>\n<h3>Does a square wedding invitation cost more to mail?<\/h3>\n<p>Yes. Square envelopes &#8211; regardless of size &#8211; are classified as non-machinable by USPS because they cannot be processed by standard letter-sorting equipment. The current non-machinable surcharge is $0.49 per piece, applied on top of the standard First-Class letter rate. Budget at least $1.27 per outer envelope for a square suite weighing 1 oz or under.<\/p>\n<h3>What is the proper way to address a wedding invitation?<\/h3>\n<p>Use full formal names on the outer envelope (no nicknames, no abbreviations except titles), spell out &#8220;and&#8221; rather than using an ampersand, and include the full mailing address. For detailed guidance on couples with different surnames, families with children, and professional titles, see our full <a href=\"\/blog\/how-to-address-wedding-invitations\/?utm_source=paperlust&#038;utm_medium=internal_link&#038;utm_campaign=cross_sell\" target=\"_blank\" rel=\"nofollow\">wedding invitation addressing guide<\/a>.<\/p>\n<h3>Can I get envelopes with addresses printed on them?<\/h3>\n<p>Yes. Paperlust offers envelope address printing as an add-on to any invitation order. Addresses are printed in a calligraphic or script font that coordinates with your suite&#8217;s typography. Import your guest list via Excel spreadsheet through the Address Manager tool and each envelope is addressed during the same production run as your cards. Pricing is approximately $0.20 per envelope.<\/p>\n<h3>How many extra envelopes should I order for my wedding?<\/h3>\n<p>Order 10-15% more than your confirmed guest count. On a 100-guest list, order 110-115 envelopes. This buffer covers addressing errors, last-minute guest list additions, and any damaged pieces from shipping. When ordering through Paperlust, mention your preference for extras during the proof review and the team can adjust your quantity.<\/p>\n<h3>What is the difference between inner and outer wedding envelopes?<\/h3>\n<p>Outer envelopes are the mailing envelopes with the formal guest address. Inner envelopes are an optional second envelope placed inside the outer &#8211; they hold the invitation suite directly and are traditionally addressed more casually (guest first names only). Inner envelopes are never sealed. Most US couples today skip the inner envelope entirely and use a single outer envelope; for formal or traditional weddings, using both is still the correct approach.<\/p>\n<h3>What are the most popular envelope colors for weddings in 2026?<\/h3>\n<p>White and cream remain the defaults. Dusty sage, blush, and warm terracotta are popular for garden and botanical suites. Black with white-ink addressing is a growing choice for evening and black-tie celebrations. Kraft natural paper suits organic, bohemian, and outdoor aesthetics. All color envelopes are ordered as upgrades alongside your invitation suite.<\/p>\n<h3>What is an A9 envelope used for in weddings?<\/h3>\n<p>A9 envelopes (5.75&#8243; x 8.75&#8243;) are used for larger-format invitation cards or suites with multiple enclosure cards that create a taller assembled stack. They mail at the same First-Class letter rate as A7 envelopes &#8211; no postage penalty &#8211; provided the suite stays under \u00bc&#8221; thick and 3.5 oz. If your 5&#8243; x 7&#8243; suite feels packed in an A7, moving up to A9 is the straightforward solution.<\/p>\n<p><script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What size envelope do I need for a 5x7 wedding invitation?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"You need an A7 envelope, which measures 5.25\\\" x 7.25\\\".
