Mailing Envelopes
Size follows the fold, and getting it backwards means the whole run is wrong. An A4 sheet folded in thirds fits DL, folded once fits C5, and unfolded needs C4. Pocket styles open on the short edge and suit anything bulky or machine-inserted, while wallet styles open along the long edge for hand filling. Seal type then decides speed. See DL, C4 and pocket envelopes.
Mail envelopes FAQs
What size mail envelope do I need?
Match the envelope to how the paper is folded. An A4 sheet folded in thirds fits a DL envelope, folded in half fits C5, and unfolded fits C4. DLX envelopes are a little larger than DL for easier insertion.
What is the difference between pocket and wallet envelopes?
A pocket envelope opens on the short edge. A wallet envelope opens on the long edge, which makes it quicker to fill by hand.
What does secretive mean on an envelope?
A secretive envelope has a tinted or printed inside so the contents cannot be read through the paper. Non-secretive envelopes are plain inside.
Peel and seal, self seal or lick and stick?
Peel and seal has a strip you remove before closing. Self seal presses shut without a strip. Lick and stick has a gummed flap that needs moistening.
