Postcard mailer sizes

Here are some common sizes for postcard mailers:

  1. Standard Postcard Size: 3.5 x 5 inches (8.9 x 12.7 cm)
    • This is the most common size for postcards and fits easily in a standard #10 envelope.
  2. Large Postcard Size: 4 x 6 inches (10.2 x 15.2 cm)
    • This size is slightly larger than the standard postcard size and can hold more information or a larger image.
  3. Jumbo Postcard Size: 5 x 7 inches (12.7 x 17.8 cm)
    • This size is even larger than the large postcard size and can hold a lot of information or a large image.
  4. Square Postcard Size: 4 x 4 inches (10.2 x 10.2 cm)
    • This size is perfect for square-shaped designs or for sending a small, square-shaped promotional item.
  5. Mini Postcard Size: 2 x 3.5 inches (5.1 x 8.9 cm)
    • This size is great for sending a small, compact message or for use as a business card.
  6. Greeting Card Size: 5 x 7 inches (12.7 x 17.8 cm)
    • This size is similar to a standard postcard, but is often used for greeting cards or other types of mailers that require a more formal design.

Keep in mind that these sizes are general guidelines, and you should check with your local post office or mail service to confirm the maximum size and weight restrictions for postcards in your area.
