DL is the UK's most common envelope size, measuring approximately 110×220mm - exactly right for a standard A4 letter folded into three. Parcelsend UK keeps DL envelopes in stock for same-day despatch, making them the go-to choice for invoices, statements and everyday business correspondence; see the wider postage envelopes range for other sizes.
How to choose the right DL envelope
DL envelopes are available windowed or non-windowed, and in self-seal or gummed closures - the right combination depends on how you're printing and filling them.
Windowed vs non-windowed
A windowed DL envelope shows the address printed on the letter itself, ideal for automated mailing runs, while non-windowed envelopes need a separately printed or handwritten address.
Self-seal vs gummed
Self-seal DL envelopes peel and stick shut in seconds, which suits high-volume hand-filling, while gummed flaps are moistened to seal and remain a familiar standard for office use.

Frequently Asked Questions
What size is a DL envelope?
DL measures approximately 110×220mm, making it the standard size for an A4 sheet folded into three - the most common format for UK business letters.
Will a DL envelope fit an A4 letter?
Yes, provided the A4 sheet is folded into three equal sections first; folded any other way it's unlikely to sit neatly inside the envelope.
Do you stock windowed DL envelopes?
Yes, both windowed and non-windowed DL envelopes are held in stock, so your printed address can show through the window or you can address the envelope separately.
Can DL envelopes be custom printed with my branding?
Yes - our personalised envelopes collection covers custom-printed DL sizes; upload your artwork online and we start production once you've approved a free sample.
Are self-seal DL envelopes better than gummed?
Neither is objectively better - self-seal is faster for hand-filling large batches, while gummed flaps are a familiar, cost-effective standard many offices already use.
How quickly can I get DL envelopes delivered?
DL envelopes held as plain stock are despatched the same day when ordered before our daily cut-off, with free UK delivery on orders over £100.
