Looking for an envelope size that's perfect for everyday use? Consider the DL envelope - the most popular size for 'letter envelopes'. With dimensions of 110 x 220mm, DL envelopes are ideal for holding A4 sheets folded twice or A5 sheets folded once. Whether you're sending letters, cards, or other correspondence, the DL envelope is a reliable and versatile option.
When you need an envelope that's slightly larger than the standard A4 size, consider the C4 envelope. Measuring 324mm by 229mm, these envelopes are often referred to as A4 envelopes because an unfolded A4 sheet fits perfectly inside. Additionally, a piece of A3 paper can be folded in half and easily fit within this envelope. However, because of their larger size, C4 envelopes may not be eligible for regular postage stamps and may need to be sent as a 'large letter', requiring a visit to the post office for weighing and sending.
Looking for an envelope that's perfect for sending unfolded A5 documents or folded A4 documents? Consider the C5 envelope. With dimensions of 162 x 229mm, the C5 envelope is a popular choice for a range of correspondence needs. What's more, it's classified as a 'letter' for postage purposes, so you can use a standard postage stamp when sending. Whether you're sending out invitations, letters, or other materials, the C5 envelope is a reliable and versatile option.
If you're looking for an envelope that's taller than a DL but not as wide, consider the C6 envelope. With dimensions of 114mm by 162mm, it's ideal for sending unfolded A6 or folded A5 documents, as well as A4 paper folded into quarters. Best of all, C6 envelopes can usually be posted using a regular stamp, making them a convenient and cost-effective option for your correspondence needs. So whether you're sending out personal letters, business correspondence, or invitations, the C6 envelope is a great choice.
The C7 envelope size is ideal for RSVP cards or invitations. Measuring approximately 83mm by 112mm, it can fit a piece of A5 or A7 paper folded into four. Despite being one of the least popular sizes, it can be posted using a regular postage stamp.
The C3 envelope is the perfect size for larger documents, specifically designed for A3 paper. With measurements of approximately 324mm x 450mm, it can easily accommodate unfolded A3 sheets.
Some of the less popular sizes of envelopes are:
- C8 57mm x 81mm - An A8 piece of unfolded paper will fit into a C8 envelope
- C9 40mm x 57mm - An unfolded piece of A9 paper will fit into a C9 envelope
- C10 28mm x 40mm - An A10 piece of unfolded paper will fit into a C10 envelope
