DL Envelopes

DL Envelopes are the most popular envelope size format in the UK today, commonly used for bills, statements, and generic letters as the DL envelope size is 110 x 220mm, conforming to a Royal Mail Letter. Our range includes both white envelopes and brown DL envelopes, and both are available with and without an address window depending on your labelling preference. All of these office envelopes can be effortlessly closed due to their self-seal gummed strip; simply press down for a strong and secure closure.  Supplied with 500 envelopes per box for minimal storage requirements and perfect for bulk mailing. These DL envelopes deliver a considerable saving by folding A4 documents into three, or A5 into two instead of using C4 envelopes or C5 envelopes. Swapping to a smaller envelope can significantly reduce your postal costs – read our Royal Mail Size Guide for more information.
