Envelope Sizes and Their Uses
Posted by Beagle Legal on Oct 6th 2016
One of the most common mistakes businesses make is sending out company materials in boring, ill-fitted envelopes. Considering the importance of personal & corporate security as well as identity theft, a plain white envelope just doesn’t cut it anymore. In addition, no one likes to receive an envelope that has been damaged by water and the elements, especially when the contents of the envelope are important legal or financial documents.
BeagleLegal.com offers a variety of envelope sizes to perfectly match their contents. After choosing the type material for an envelope, the next step is picking out the correct size.
Standard Envelopes and Business Envelopes
The ubiquitous #10 Envelope is the most popular business and commercial envelope in the United States. Different styles of flaps and stock continue to boost its popularity. Choose from the following options for #10 envelopes and additional sizes:
Commercial Flap and Side Seam—ideal for running through machines
Wallet Flap—offers a large area for printing options
Policy—great for important documents like legal papers
Square Flap—perfect for invitations, announcements and cards
