Mitered Square Formula

After perusing a million patterns for mitered squares, and not really getting any of them, I have finally compiled all the data and cracked the code.

Knit Mitered Square

This is a basic formula to make mitered squares. You can do this with any yarn/needle combo and the uses for the squares once made are endless!


  • Yarn -Any weight , small amount
  • Needles Appropriate to Yarn
  • Usual notions: scissors, darning needle etc.
  The Process: A Bit O' Math:

  1. Pick a nice even number where each side of your square will be half that many stitches. We will call this number X. (Here it helps to have an idea of the desired size and an estimate of your gauge for your needle/yarn combination. If you have stitches per inch and a desired number of inches then getting a square of any size is easy.)
  2. Cast on X+1 stitches.
  3. Knit this first row. (WS)
  4. (RS) Knit ½ X-1 stitches, knit three together, knit to the end. (Here any double decrease will work, I like to knit 3 together into the back of the stitches, but it really doesn't matter as long as you always use the same method.)
  5. Knit a row.
  6. Knit ½ X-2 stitches, knit 3 together, knit to end
  7. Knit a row.
  8. Repeat in this manner doing a double decrease around the center stitch on each RS row and knitting all WS rows.
  9. When you are down to five stitches: S1, K1, PSSO, K1, K2Tog then cut your working yarn and thread it through the remaining three stitches and pull tight/tie off.
  10. Finish as desired.
Once you get going it become quite easy to tell where to do the decreases, but for an example of the math I use worsted weight yarn with size 8 needles: Cast on 37 stitches, knit the first row, knit 17 stitches, K3tog, knit to end, knit the next row, knit 16 stitches, K3tog, knit to end…you get the idea. This gives me a 4 inch square.
