Can you mail 10x13 envelopes

Yes, you can mail 10x13 envelopes, but there are some considerations to keep in mind:

  1. USPS regulations: The United States Postal Service (USPS) allows mailing of envelopes up to 13 inches long, but there are some restrictions on the thickness and weight of the envelope. According to USPS, the maximum thickness for a letter-sized envelope (up to 13 inches long) is 3/4 inch (1.9 cm).
  2. Size and shape: 10x13 envelopes are considered non-standard sizes, which may affect their mailing costs and delivery times. Standard letter-sized envelopes are typically 6.125 inches wide and 9.5 inches long.
  3. Weight and thickness: If your 10x13 envelope is too thick or heavy, it may not be eligible for standard mailing rates. You may need to use a larger envelope or a package service, such as Priority Mail or Parcel Post, which can be more expensive.
  4. Special handling: Due to their non-standard size, 10x13 envelopes may require special handling by the USPS. This could result in longer delivery times or additional fees.
  5. Private carriers: If you're using a private carrier like FedEx or UPS, their regulations and pricing may vary. You should check with the carrier for their specific guidelines on mailing 10x13 envelopes.
