I needed to be able to scale this pattern up and down, so I have been working on an excel spreadsheet all summer. My two favourite ways of machine knitting socks are a sayg sock, and the other one is a one-seam sock. When someone asks me to make a sock, I don’t always have a tape measure handy, so I ask for their shoe size. I found this chart with standard shoe sizes that list the corresponding foot length in inches, and applied the math.
Calculate the sock:
1. Circumference x stitch gauge = how many you cast on.
2. Rib desired length. I usually do 2″ here.
3. Knit desired length. I have found less than 4″ really doesn’t cover the ankle, so that’s my minimum.
4. Begin the short row heel: 1/4 or 1/3 of cast on stitches are put in the hold position. 1/3 of cast on stitches will create a deeper heel than 1/4, but both work just fine!
5. Knit the length of the foot x row gauge, MINUS the short rowed heel length.
6. Begin the short row toe the same as the heel.
7. Scrap off and sew up.
