Any Size Envelope

by Nancy Stislow

Learn how to create an envelope for any size card.


  • Scoring Tool
  • Paper trimmer or knife, ruler and cutting mat
  • Corner rounder
  • Adhesive - double sided tape or glue
  • Scissors
  • Cardstock (double-sided cardstock and designer paper work beautifully for this)
  • Finished card


  1. Step 1

    Check the length of the paper for correct size by flipping the finished card twice over the cardstock. Leave about 2" extra. No need to be exact. Trim excess if necessary.

  2. Step 2

    Rotate the cardstock leaving the card in place. Lay the card approximately 1" from the side.

  3. Step 3

    Trim the opposite side so that there is 1" of cardstock on either side of the card.

  4. Step 4

    Lay the paper with the card on scoring board so that the card is centered at the top of the board. Score1/8" away from both edges of the card.

    Black lines show score lines used here.

  5. Step 5

    Rotate the cardstock with the card in place on the scoring board to score the flaps. Slide the card up to the top of the scoring board. Score one notch 1/8" away from both edges of the card.

  6. Step 6

    The cardstock should now have four score lines.

  7. Step 7

    Cut out the four corners as shown.

  8. Step 8

    Round 4 corners of the cardstock.

  9. Fold the flaps down and round the 4 remaining corners.

  10. Step 9

    Apply adhesive to the lower flap.

  11. Step 10

    Finished! Embellish your envelope if desired.

    This works with any size card. However if the card is 5x5 or greater, a larger paper must be used- even a grocery bag, heavy weight gift wrap or legal paper.



  1. For the math wiz:
    - To figure out the length of paper needed the short side of card multiply it by 2 and add 2". (short card size x 2 + 2" = paper length).
    - Measure the long side of the card and add 2". ( long side + 2" = paper width).
    - Score at 7/8" on each side of the paper width.
    - To figure out where to score on the long side of the paper, subtract the short side of card from the paper length, divide by 2 and subract 1/8". ((paper length - short side of card) / 2) - 1/8" = where to score each side of the long side of paper.

Thank you for showing how easy this can be. I have been trying to figure it out in my mind for months. I was over thinking it!

Thank you! I can now make envelopes for A5 cards without worrying about trying to find them in the shops or paying expensive postage prices!

Thanks for a much needed tutorial. Now my larger oblong stamps can be used without worrying about finding an envelope to fit. And what a way to recycle the grocery bags.

Thank you for giving me the option of using something but the standard size card. Now, I can use my pattern paper to make the envelopes too. The tutorial was just perfect!

Wonderful tutorial and easy to follow for this math challenged human! many thanks for the may I ask you to go back to the drawing board? or more specifically, the DIAGONAL scoring board that SU has? I've been trying, with little success to come up with measurements for "different" sized cards...thanks in advance!

Hi Connie! One of our members posted a document with measurements for making envelopes with that board:

Thanks for sharing this incredibly easy tutorial! Ever have one of those "why didn't I think of that?" moments?
