C Sizes Are For Envelopes Made To Hold A Sized Paper
C sizes are paper sizes used for envelopes, designed to take ‘A’ sized paper. We offer C4 (324 x 299 mm), C5 (229 x 162mm) and DL (220 x 110mm) sized envelopes.
C sized envelopes are the right choice for letters and compliment slips.
Top tip: Choose DL for a folded letter and com slip – more cost-effective
