10 Business Envelopes - 4 1/8 x 9 1/2

Mailing a standard #10 envelope through USPS currently costs one First-Class Mail stamp for items weighing up to 1 ounce. Additional ounces incur a small surcharge. Rates may vary if the envelope contains rigid inserts or is non-machinable. Always verify current postage rates at the USPS website before mailing.

The #10 designation comes from the envelope sizing system historically used by the paper and mailing industry in the United States. The number does not directly relate to dimensions but rather identifies a standardized slot in the commercial envelope lineup. The #10 became the dominant standard for business mail due to its compatibility with tri-folded letter-size documents.

Minuteman Press of Chantilly prints #10 business envelopes on 90 gsm (grams per square meter) smooth, matte, bright white paper. This weight provides a professional feel that is sturdy enough for mailing while maintaining a clean, crisp surface for sharp logo and text printing.
