What is a standard size envelope?



This is a question we get asked surprisingly often. The sizing system for envelopes can be confusing.  How do you know if you need a DL Wallet or a C5 Pocket?  We can explain all...

The most common envelope for business use is the DL wallet.  This will fit a piece of A4 paper folded three times and is commonly used for sending letters. ‘Wallet’ just means it opens at the widest side, so in this case, the top of the envelope. ‘Pocket’ is the opposite. DL stands for ‘Dimension Lengthways’, although the abbreviation is favoured and the longhand term is very rarely used.

The other common envelope sizes are the ISO 216 ‘C’ sizes, based on the ‘A’ paper standards, so C4 will hold an A4 sheet of paper unfolded, C5 will hold an A5 piece of paper and so on. Sizes range from C0 to C10.

For a quick reference we have provided a graphic for you to print out and keep by your desk.

  2. Thanks for breaking down the different envelope sizes so clearly — this is super helpful for businesses navigating print and mailing logistics. From a B2B standpoint, having a reliable supplier for Envelopes in the UK is critical for companies that regularly send out marketing collateral, invoices, or promotional booklets. Understanding the standard dimensions not only streamlines the procurement process but also ensures compatibility with printers and postal regulations. Great practical guide!
