Envelopes come in a variety of sizes, shapes, and methods of sealing. The envelopes are ranked in numerical sequence to specify the dimensions and specifications of the envelope. The ranking for the majority of the envelopes range from #3 to #14. Some manufacturers customize envelopes to additional sizes and ranks. The #10 envelope is the most common size used for business and personal correspondence. - All #10 envelopes use the same exterior dimensions. The envelope is 4.125 inches long and 9.5 inches wide. The envelope is capable of holding papers measuring 9.25 inches wide by 3.875 inches long. The internal capacity can hold a standard letter-size page, 8.5 inches wide by 11 inches long, folded in thirds lengthwise. The envelope does not have a maximum number of sheets it can hold. Depending on the paper's weight, most #10s can hold up to ten sheets of standard paper, folded in thirds, without ripping. The number of pages placed in the envelope, however, could affect postage costs.
- The #10 envelope have numerous sealing options. The most common style uses a triangle-flap enclosure with dry glue you moisten to seal. Another common variety uses a square-flap enclosure available with self-adhesive seals or the standard seals. Many businesses use a #10 envelope with one or two viewing windows. The window envelopes are typically positioned where the address and/or return address would appear. Each separate address is then printed on the document to be printed, such as a bill, and folded so the addresses can be seen through the appropriate windows. Like all envelopes, the #10 window envelope is available in a large variety of colors and designs.
- Customizing a #10 envelope is simple. Contact your local printing company to purchase the envelopes in bulk with a company name or design printed on the envelope, or you can use normal office or image software to customize the envelope. If using your own software, you must input the width and length of the envelope into the "Page Setup" options to accurately print a custom image onto the envelope. Be careful when customizing envelopes. The U.S. Postal Service requires that the mail-to and from address be clear and legible. Do not print images over the areas typically used for the address or stamp.
