A5 envelopes are also referred to as C5 envelopes and are among some of the most common envelope sizes. Learning more about its size and weight can assist you in determining what can be accommodated within an A5 envelope size and what your potential postage expenses might be.

Dimensions of an A5 envelope size:

An A5 envelope’s length is 22.9 cm (or 229 mm), while its height measures 16.2 cm (or 162 mm), slightly larger than an A5 piece of paper or an A4 piece of paper folded in half. You can also choose from a selection of sealings and whether you require an address window or not.

Envelope weight:

The width or thickness of an A5 envelope depends on its brand and the type of paper it’s constructed from. Most A5 envelopes are approximately 70-100gms. This thickness generally allows them to hold several sheets of paper, given that A5 envelopes are designed for folded sheets. However, if the envelope is crafted from heavier-duty paper, it may be slightly thicker. Thicker envelopes may accommodate fewer sheets.

An alternative to the C5 envelope is a C4 envelope. A C4 envelope fit’s an unfolded A4 piece of paper.
