Introduction
A wedding has four mailing moments, and each needs its own envelope: save-the-date, invitation, RSVP and thank-you. Getting the envelopes right means matching sizes to cards, paper to formality, and printing to the couple’s style.
Wedding invitation envelopes are where stationery design meets production reality — this guide covers the complete flow, sizes, paper, printing and the addressing etiquette that keeps every piece looking cohesive.
The Four Mailing Moments
| Moment | Card | Envelope |
|---|---|---|
| Save-the-date | 4¼ × 5½ postcard or card | A2 (4⅜ × 5¾) or A6 |
| Invitation | 5 × 7 card + inserts | A7 (5¼ × 7¼) or Baronial |
| RSVP | 3½ × 5 card | A2 (4⅜ × 5¾) with peel-seal |
| Thank-you | 4¼ × 5½ card | A2 or A6 |
Envelope Sizes for Weddings
| Envelope | Dimensions (in) | Wedding Use |
|---|---|---|
| A2 | 4⅜ × 5¾ | RSVP, save-the-date, thank-you |
| A6 | 4¾ × 6½ | Save-the-date, flat cards |
| A7 | 5¼ × 7¼ | Standard invitation |
| Baronial | 4⅞ × 6⅞ | Formal invitations (pointed flap) |
| Square | 5½ × 5½ | Modern, non-traditional weddings |
| Pocketfold | Variable | Invitation suites with multiple inserts |
Manufacturer’s note: Invitation cards fit with ~⅛ in margin per side. A 5 × 7 invitation needs an A7 envelope; squeezing it into A6 damages corners. When in doubt, size up.
Paper and Finish Selection
| Style | Paper | Finish |
|---|---|---|
| Classic formal | 80–100 lb text | Smooth, white or ivory |
| Rustic | 80 lb kraft/recycled | Natural, textured |
| Modern | 80 lb smooth | Clean, minimal, maybe foil |
| Luxury | 65–80 lb cover | Laid/felt texture, foil, emboss |
Finishes that read “wedding”: foil stamping (gold/silver/rose gold), letterpress-style embossing, thermography, and decorative envelope liners. See invitation envelope standards for the full specs.
Addressing and Etiquette
- Outer envelope — formal: “Mr. and Mrs. John Smith”; casual: first names
- Inner envelope — optional second layer, traditionally more informal
- Return address — top-left front or back flap (European style)
- Stamps — pre-affixed stamps are a production option; see personalized stamped envelopes
- Postage — check weights! Invitation suites with liners and multiple inserts can exceed standard letter rates
Ordering for Weddings
- Quantities — count 10–15% over your guest list for mistakes, late additions and keepsakes
- Proofing — always approve a hard proof before the full run; wedding colors must match (ΔE ≤ 2.0)
- Lead time — order 8–12 weeks before the mailing date; production plus addressing plus stamps takes time
- Small runs — digital printing makes 100–500 piece runs economical
FAQ
What size envelope do I need for a 5×7 wedding invitation?
An A7 envelope (5¼ × 7¼ in). The card fits with ⅛ in clearance on each side.
Do I need inner and outer envelopes?
Traditional formal weddings use both; most modern weddings use a single envelope. Both styles are correct — consistency matters more than the rule.
What is the standard wedding invitation envelope size?
A7 (5¼ × 7¼) is the most common; Baronial (4⅞ × 6⅞, pointed flap) for classic formal invitations.
Can I print names and addresses on wedding envelopes?
Yes — printing is faster and more consistent than handwriting. Calligraphy-style fonts on the envelope print beautifully with the right file. See print-ready standards.
How many extra envelopes should I order?
Order 10–15% extra for addressing mistakes, last-minute guest additions and keepsakes. It’s the cheapest insurance of the whole wedding.
Do you print small quantities of wedding envelopes?
Yes — digital short runs from 100 pieces. Request a quote for pricing and samples.
