The correct way to address an envelope is to write the recipient's (delivery) address in the center of the envelope. Include the recipient's full name on the first line, street address (and apartment/unit number) on the second line, and city, state abbreviation, and ZIP code on the third line. The return address goes in the upper-left corner. For USPS mail, use uppercase letters and avoid punctuation for fastest processing.

The return address should be placed in the upper-left corner of the envelope, about 0.25 to 0.5 inches from the top and left edges. It typically uses a smaller font size than the delivery address. If you're using pre-printed envelopes with your return address already on them, you can skip this step.

The #10 envelope (4.125" × 9.5") is the standard size for business letters in the United States. It fits a standard letter-sized paper (8.5" × 11") folded into thirds. For formal invitations, A7 envelopes (5.25" × 7.25") are popular. For international correspondence, the DL envelope (110mm × 220mm) is common in Europe and fits A4 paper folded into thirds.

Most modern printers have an envelope feeder slot. Load your envelope into the feeder according to your printer's instructions (usually flap side down, with the delivery address facing up). In your printer settings, select the correct envelope size (e.g., #10, A7, DL). Use this tool to preview the layout, then click Print. Always do a test print on plain paper first to verify alignment.

Yes! This tool supports international addresses. For international mail, include the destination country in all capital letters as the last line of the delivery address. The USPS recommends placing the country name in English. Remember that international mail requires additional postage, and format conventions may vary by country.

For business correspondence, a clean sans-serif font like Arial or Helvetica is preferred for readability. For formal occasions like weddings, a serif font (Times New Roman, Georgia) or an elegant script font adds a personal touch. The USPS recommends using a simple, readable font in a size of at least 10-point for the delivery address. Avoid overly decorative fonts that may confuse postal scanning equipment.

USPS recommends: 1) Use uppercase letters for the delivery address. 2) Avoid punctuation (no periods or commas). 3) Use standard 2-letter state abbreviations (e.g., CA, NY, TX). 4) Include the full 5-digit ZIP code; ZIP+4 is even better for faster delivery. 5) Left-justify the address block. 6) Use a minimum 10-point font. 7) Keep the address block within the OCR read area (roughly the center of the envelope).
