ENVELOPE TYPES AND SIZES IN DENVER, CO
Getting the right size envelope for your marketing piece or card can be a critical step in how your message is received. At AlphaGraphics Denver, we’ll help you get the right type of envelope and the right size for your mailing so that you make a great impression.
THE RIGHT SIZE FOR THE RIGHT OCCASION
The right envelope size is going to be determined by the contents of the envelope – this makes perfect sense. You want enough room to easily slide the card or insert easily in and out, but not with too much space that it seems loose or undersized for the envelope.

- A7 – Measures 5.25” x 7.25” and fits a flat or folded card sized 5” x 7”
Booklet and Catalog Envelopes – Booklet envelopes open on the long edge and catalog envelopes open on the short edge of the envelope. Choose your envelope type based on what you’re mailing and the envelope opening interaction you want.
