There are many different sizes for envelopes. From A-0,1,2,3.....10 for greeting cards or thank you cards, to B-0,1,2,3.....9 for lessor common trimmed sizes.
The most common envelopes are standard #9 or #10. When ordering, take into account the finish: smooth, linen, vellum, felt, laid, etc., and how many ink colors (from 1 color to full color) you would like. We have samples of the different stock colors and finishes for you to look at and feel before you order.
You may take into consideration a blue inside security tint, or a window envelope. You can also order a #9 return envelope complete with your postal bar code on the address. This way you can send your invoices out in a #10 and enclose a #9 for your customer’s convenience in mailing you back.
