Envelope Size Chart

We specialize in creating your vision from start to finish, so we don't generally do standard. However, below you will find typical sizing for many common envelopes. Envelopes are often classified in groups:

Commercial

Commercial envelopes are most often used for direct mail, invoices, checks and statements due to their machine insertion efficiencies.

A-Style

These envelopes fall into the social announcement category and will often have a square flap. A-style envelopes are often used for invitations, smaller brochures, booklets and promotional pieces, as well as business stationery.

Baronial

Used for many applications ranging from commercial to social, the baronial style envelope often has a pointed flap. 

Booklet

Booklet envelopes are used for heavy duty mailing and shipping requirements for annual reports, sales literature, and booklets. The booklet style construction has a side opening and the flap style allows for machine insertion.

Catalog

Like the booklet envelope, catalog style envelopes are used for heavy duty mailing and shipping requirements for items such as magazines, catalogs, and sales literature. The center seam of catalog envelopes makes them more durable and ideal for mailing heavier materials.
