What Size Are C4 Envelopes?

A C4 envelope measures 229 x 324 mm, which corresponds to a standard A4 sheet (210 x 297 mm).

This means that a C4 envelope can hold an A4 document without folding, ensuring that papers arrive flat and without creased corners.

Understanding paper sizes can sometimes be confusing, so here are a few key details:

Paper sizes follow the international DIN standard, which consists of five series (A, B, C, D, and E). The most common format is DIN A4, but all paper sizes originate from DIN A0 (1682 x 2378 mm).

For envelopes, the C series is used, with sizes numbered from C0 to C10. Each C-series envelope is designed to fit its corresponding A-series paper size.

Here’s how C-series envelopes compare to standard paper sizes:

• C3 envelopes (324 x 458 mm) → Fit A3 paper (297 x 420 mm)
• C4 envelopes (229 x 324 mm) → Fit A4 paper (210 x 297 mm) without folding
• C5 envelopes (162 x 229 mm) → Fit A5 paper (148 x 210 mm)
• C6 envelopes (114 x 162 mm) → Fit A6 paper (105 x 148 mm)
