How to Find the Right Envelope Size for Your Invitation

LCI Paper supplies blank and printed envelopes in dozens of sizes, and finding the right size envelope for your invites or cards may be tricky.  Here we explain how to choose the right size envelope.

Choose Your Envelopes Before Your Cards!

Where cards can be cut into any size, envelopes are made only in standard industry sizes. Before designing or purchasing your invitations, be sure a suitable envelope will be available. 
 

Pair Cards with Envelopes that are 1/8 – 1/4 Inch Larger than Your Cards

The guideline to the perfect fit is an envelope that is 1/8 to 1/4 inch larger than your largest card. This will allow plenty of room for your card(s) without excessive wiggle room that may make your presentation look sloppy.


An Easy Way to Find the Right Envelope Size, Match the A-Sizes

To make it easy (and to avoid measuring), check out the A-sizes!

Standard “A” Sizes (A1, A2, A6, A7, etc.) are designated with an A followed by a number. A-sizes correspond to specific card and envelope sizes. For simplicity, a card and envelope with the same A-size are designed to be paired together.

For example, A7 size cards and A7 size envelopes are the perfect fit:

A7 card size: (5 1/8 x 7)

A7 envelope size: (5 1/4 x 7 1/4)
