How do I Select the Appropriate Envelope Size for any Mailing? Let's Clarify Your Concepts

Measure your contents carefully by first determining the width and height of what you are sending while it is flat, including inserts, backing cards, or return envelopes in your measurements.

Next, decide whether to fold or mail flat, as folding allows you to use smaller envelopes, such as a #10 for letters, whereas sending items flat requires larger sizes like 9 x 12 or 10 x 13. Thereafter, make sure to add proper clearance by selecting an envelope that is at least one-quarter inch larger than your contents on all sides.

Since thicker inserts may require additional space, in addition, choose the appropriate opening style, where booklet envelopes open on the long side and are quicker to fill, while catalog envelopes open on the short side and provide better support for documents.

Finally, consider the thickness and weight of your items, as bulky or multi-page mailings may require booklet or expansion envelopes to avoid tearing.
