Dlx Envelopes

The extra clearance sounds trivial and is not: a folded A4 letter into a true DL is tight, and on a folder-inserter that tightness becomes a jam rate. DLX takes the same letter with room. Confirm which your equipment and your window template assume before ordering a full carton of either. See correspondence envelopes, pocket envelopes and packaging envelopes.

DLX envelopes FAQs

What size is a DLX envelope?

A DLX envelope measures 120 x 235mm, a little larger than a standard DL envelope.

Will A4 paper fit in a DLX envelope?

Yes, folded in thirds. DLX gives extra room around the folded sheet, which helps when filling envelopes by hand or with a folder-inserter.

Which brands and pack sizes are available?

DLX envelopes here are from Candida and Cumberland, in plain and window face, mostly in boxes of 500. See all mail envelopes for other sizes.
