For something that is so simple there is a lot of choice when it comes to selecting your envelopes. As well as choosing the size you also need to decide if you would like a window to display the recipient’s address, the method of closing the envelope and whether they need to be padded or protective in any way. To help with all these decisions we’ve created a handy guide to envelopes to help you select the most suitable products for your requirements.

C4 Size Envelopes - Sometimes called A4 envelopes as you can fit a piece of unfolded A4 paper into them. C4 Envelopes are one of the most common sizes and are used for sending items such as reports or brochures.
C5 Size Envelopes - Suitable for an A4 for sheet of paper folded in half or an unfolded piece of A5 paper. C5 Envelopes are commonly used for mail shots or business letter.
C6 Size Envelopes - This size envelope is not generally used by businesses and is instead popular for sending greeting cards or post cards.
DL Size Envelopes - Are suitable for an A4 piece of paper folded twice so the finished sheet is a third of the unfolded size. A very common business size envelope used for sending letters and invoices.
Protective Envelopes - If the items you are posting are important and require some form of protection as they pass through the postal system then you have some excellent options. To prevent bending of documents board backed envelopes are available. If you need to ensure your items stay dry then water proof polythene bags can be used.
Gusset Envelopes - If you need to send over sized items such as books, magazines or manuals then gusset envelopes provide an ideal solution. Available with either a ‘Block Bottom’ or V-Shaped Bottom’ which allow the envelope to expand to accommodate larger items.
Padded Envelopes - Padded bags are commonly known as bubble bags and Jiffy bags and provide protection for delicate or bulky items which are to be sent through the post. They are generally made with a tear resistant outer layer that surrounds a bubble lined interior.
