C6 Envelopes are one of the less popular sized envelopes and generally are not a size used by business. C6 envelopes measure 114mm x 162mm which is the equivalent of an A4 sized piece of paper folded in half twice. C6 envelops are also the same size as a postcard and it is for sending these that they are used most frequently. Due to their small size they fall into the lowest cost Royal Mail postage bracket which does make their use by business economical particularly for sending mailers or promotional offers to new or existing customers.
