C4 envelopes measure size 229mm x 324mm and this is the most common size of large letter mailing undertaken. C4 envelopes are designed to fit A4 paper size and can standardly take approx 50 pages. If the brochure or literature going inside the envelope is heavy of too thick we would suggest using a C4 gusset envelope with 25mm capacity, these are made from 140gsm paper which is stronger than the standard C4 envelope. If the item going inside the envelope are very heavy you may require a tear resistant envelope. As with all our C4 envelopes we can send samples free of charge.

C4 envelopes are available in various shades of white for example we have a cream C4 120gsm peel & seal envelope also in other shaded of off white. To add to this collection we supply a huge range of coloured and board coloured envelopes. As with all the other size envelopes C4 envelopes can be gummed mailing wallets, self seal & higher quality envelopes which come as a peel & seal and are usually 100gsm – 120gsm but do go up to 180gsm which is the thickest envelope which we overprint.
