How You Can Send A Square Card Without Extra Postage? Video Tutorial

Day 2 in the Mailing handmade cards series. It was brought up on my Facebook Page that square cards require extra postage so I started thinking about the possibilities. I came up with an envelope that is a rectangle so you would not require extra postage, but would look nice for a square card.

Letter Sizes


  • Maximum weight is 3 1/2 oz.
  • Must be rectangular.
  • Minimum size is 5″ long x 3 1/2″ high x 0.007” thick.
  • Maximum size of 11 1/2″ long x 6 1/8″ high x 1/4” thick.
  • Maximum weight is 3.5 oz.
  • A letter will be charged a nonmachinable surcharge if it’s a square letter 5″ x 5″ or larger, it doesn’t bend easily, has clasps or similar closure devices, has an address parallel to the shorter dimension of the letter, is lumpy, or the length divided by height is less than 1.3 or more than 2.5.

For a 6″ X 6″ card,  the minimum size is 6 1/8″ X 8″. If you make it shorter than 8 inches it will be less than the 1.3 aspect ratio.

I found this information at:

Directions to make Envelope:

  • I started with a 11″ X 11″ piece of DSP Patterned Paper.
  • I scored it at 4 3/8″ along the top and 4 3/8″ down the side.
  • I then turned the paper 90 degrees and scored the top at 5 5/8″ and 5 5/8″ down the side.
  • Fold all score lines.
  • Snip the top corners.
  • Fold down the bottom peak and trim.
  • Place some adhesive along the sides to glue together 1 inch on either side of the card.
  • Glue down the side and bottom flaps.

  1. This is SO awesome! I love the look of square cards; when I make them, they just look so much more polished, but I won’t make them to mail because of the postage. I have one at home right now that I can now mail with your envelope instructions–thank you! 🙂
