C5 envelopes measure approximately 162×229mm, making them roomy enough for an A5 sheet sent flat or an A4 document folded once. Parcelsend UK stocks C5 envelopes for same-day despatch, ideal for booklets, folded reports and mailings that don't suit the slimmer DL envelope format.
How to choose the right C5 envelope
C5 sits between DL and C4 in size, so it's worth checking whether your contents genuinely need the extra room before choosing it over a smaller or larger option.
What fits inside a C5 envelope
A C5 envelope comfortably takes an A5 sheet unfolded, or a single A4 sheet folded once in half, making it a popular choice for greetings cards, brochures and short reports.
Windowed, self-seal and gummed options
As with our other envelope sizes, C5 is available windowed or non-windowed, and with either a self-seal or gummed closure to suit your mailing process.

Frequently Asked Questions
What size is a C5 envelope?
C5 measures approximately 162×229mm - roughly half the size of an A4 sheet, and the exact size of an A5 sheet.
What's the difference between C5 and DL?
DL is the slimmer size designed for an A4 letter folded into three, while C5 is larger and suits an A5 sheet flat or an A4 sheet folded just once - see our DL envelopes for comparison.
Can I fit a folded A4 document in a C5 envelope?
Yes, a C5 envelope takes an A4 sheet folded in half, which is useful for reports or letters you don't want folded into three.
Do you offer windowed C5 envelopes?
Yes, C5 envelopes are stocked in both windowed and non-windowed versions, alongside self-seal and gummed closure options.
Can C5 envelopes be printed with a design or logo?
