These simple yet effective envelopes are perfect for general, everyday posting.

Possessing high quality design and construction, our affordable envelopes are a must-have for the office so that your workforce has the basic, necessary postal equipment at the ready .

What is the most common envelope size for business correspondence?

Each envelope size has an industry standard reference, making it easier to find the envelope for you. Size DL envelopes accommodate a twice-folded A4 piece of paper or a once folded A5 sheet of paper. Size C5 envelopes are able to fit a once folded A4 piece of paper or an unfolded A5 sheet of paper. Lastly, size C4 envelopes are able to fit a standard unfolded A4 paper. These are the most common sizes for business mailings. 

All of our white envelopes and brown envelopes are completely plain, meaning there is no window. They are great when used in conjunction with our Inkjet and Laser Printer Labels.
