How to Find the Right Envelope Size for Your Invitation

First Things First, Choose Your Envelope Size First

Where invitation cards can be cut to any size, envelopes are made only in standard industry sizes. Before purchasing or designing your invitations, be sure a properly sized envelope will be available. Custom sized envelopes are very difficult to come by and are generally made to order in quantities of several thousand or more.

Whether your invitation cards come from us or elsewhere, below you can learn how to find just the right envelope size for a professional invitation ensemble.

Golden Rule: Choose an Envelope 1/8 to 1/4 Inch Larger than Your Invitation Card

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.

Standard A-Size envelopes Make it Easy (No Measuring Required)

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, and 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)
