Perfect for larger A4 card blanks or A4 sized documents, our C4 envelopes are made from sustainable sources exclusively for Ideal Envelopes. These A4 envelopes are imported from one of our overseas manufactures, where they are cut, creased and gummed all by hand.
We stock a huge range of C4 envelopes available to buy at wholesale prices in small quantities or bulk. Most come with an option for a window and we can personalise by printing your own design, logo or address.
C4 envelopes are 229 x 324 mm or 9.01 x 12.75 inches in size and are referred to as A4 envelopes as they fit A4 sized paper or card unfolded.
A4 refers to the size of paper or card whereas C4 refers to the size of the envelope. A C4 envelope is slightly larger so that it can accommodate A4 sized paper or card unfolded. In short, you replace the A with C when choosing the envelope size.
