Zazzle Custom Stamp Information

Everything you need to know about Zazzle Custom Postage

 

Basic Zazzle Postage Info

You can select the value of the postage from any of the US Dollar ($) denominations below. All postage on a sheet (20 stamps) must have the same design and postage value, but you can order as many different sheets as you want. Zazzle does not offer custom postage denominations at this time (12 available denominations) or in any other currency besides USD ($).

Because of our postage authentication technology, most postal machines will not leave postmarks on the postage, allowing your custom image to be fully enjoyed by the recipient. 

Zazzle custom postage comes in three sizes.

Available Denominations

Please refer to the "Denomination & Size Options" or "About this product" sections on any custom postage product page for an updated list of available denominations.

Postage Sizes (Full description & ratio to envelopes)

Large

The original, full-size Zazzle Custom Stamp. It’s BIG, with the largest image area available anywhere! It looks great on standard letter envelopes and other larger sized mailings. The 8½"x11" overall sheet size for a full sheet of 20 also means it will fit easily into a frame or scrapbook, making it the perfect option for a gift to keep forever! 

Image Aspect Ratio: 5x7 

Standard Letter (#10) Greeting Card (A7) Note Card (A2) RSVP

Medium

The rectangular image area of the medium Zazzle Custom Stamp makes it a great choice for photographs and other artwork. The smaller size ensures that it will look great on smaller mailings, including greeting card envelopes and even RSVP envelopes. Of course, they also look good on standard letter envelopes as well!

Image aspect ratio: 3x4

Small

The small Zazzle Custom Stamp has a square image area, so it’s perfect for square business logos or square photographs. The small overall size means it will look great even on the smallest envelopes!

NOTE: If one of the above dimensions for the minimum envelope (6 1/8" x 11 1/2 x 1/4) are exceeded, the envelope will be considered a large envelope. For example, an envelope that is 11/2" long x 8" high x 1/4" thick would be considered a large envelope because the 8" side exceeds 6 1/8".  

 

Mailing Tips

  • 6.5" x 8.75" and square letters require different postage rates due to their odd sizes
  • Any item smaller than the minimum size requirements will not be mailable
  • Make sure to write the address parallel to the long side of your letter or postcard
  • Postcards must be rectangular and must be made of unfolded/uncreased paper or card stock
  • Large postcards that exceed the maximum dimensions above must be mailed at the First-Class mail letter postage rate
  • Letters that weigh more than 1 oz will require additional postage (see above)
  • Items larger than a large envelope are considered packages and require additional postage
