Format C sizing for envelopes

Envelope format C defines the C (N) size values ​​as the geometric mean between the sizes of the A (N) and B (N) formats, i.e. dimensions C4 is the geometric mean of A4 and B4. This results in sizes that fall between the two sizes, which, when made to size, would be ideal for transporting paper of the same size. For example, a C4 envelope is ideal for a sheet of A4 paper when unfolded.

It should be noted that C envelopes also have an aspect ratio equal to the square root of 2, and because of this, an A4 sheet folded parallel to its smaller side will easily fit into a C5 envelope, and folded twice more will fit a C6 envelope.

The following diagrams show how C4, C5 and C6 envelopes compare with an A4 sheet of paper (the envelope is shown in brown and the sheet of paper in gray), as you can see in the first diagram, a C4 envelope can fit an entire A4 sheet, A C5 envelope can hold an A4 sheet folded in half (A5 sheet) and a C6 envelope can hold an A4 sheet folded in half twice (A6 sheet). This is the reason why these envelopes are sometimes referred to as A4, A5 or A6 size envelopes.
