Large envelope mail

Large envelope mail, also known as "flat rate" or "oversized" mail, refers to envelopes that are larger than the standard #10 envelope size (4 1/8" x 9 1/2"). These envelopes are designed to accommodate larger documents, such as posters, maps, and other items that don't fit in a standard envelope.

Here are some common types of large envelope mail:

  1. Flat Rate Envelopes: These envelopes have a fixed price, regardless of the weight or size of the contents. The USPS offers flat rate envelopes in various sizes, including:
    • Large Flat Rate Envelope (12 1/2" x 15 1/2"): $13.75
    • Extra Large Flat Rate Envelope (15" x 18"): $19.75
  2. Oversized Envelopes: These envelopes are larger than the standard #10 envelope size, but not necessarily flat rate. The cost to mail these envelopes depends on the weight and size of the contents.
  3. Large Envelopes with Special Handling: Some large envelopes require special handling, such as those containing fragile or oversized items. These envelopes may require additional postage and handling fees.

When sending large envelope mail, keep the following tips in mind:

  1. Measure carefully: Make sure to measure your envelope and contents accurately to ensure you're using the correct size and postage.
  2. Use the correct postage: Use the correct postage for your envelope, taking into account the weight and size of the contents.
  3. Choose the right mail class: Select the appropriate mail class for your large envelope, such as First Class Mail, Priority Mail, or Parcel Post.
  4. Use sturdy packaging: Use sturdy packaging materials, such as cardboard or bubble wrap, to protect your contents during transit.
  5. Check with your local post office: If you're unsure about the best way to send your large envelope, consult with your local post office for guidance.

Remember to always follow USPS guidelines and regulations when sending large envelope mail.
