Flat Sock Blueprint Calculator

Put in your measurements and your blocked gauge. You get back every stitch count, every row count, and the exact rows to shape on.

Your numbers

Measure the foot that will wear the sock. Do not pull the tape tight. The calculator takes off the negative ease for you.

Foot measurements

Your gauge

From your blocked swatch, in the fabric you plan to knit for the leg and foot.

Design choices

Not eased. These are however tall you want them.

Fit

A sock is knit a little smaller than the foot so it stretches to fit. 10% is the usual starting point. Slippers can use less.

Fill in every field above and your blueprint appears here.

Finished measurements

Your measurements with 10% negative ease applied.

Your blueprint

Stitch counts at every point where the shape changes.

Schematic, not to scale. The piece folds at the toe tip and the heel center. A and B close the toe, C and D the sides of the foot, E and F the heel. G joins the top of the heel to the two bound-off edges at the leg, and H closes the back of the leg.

Your knitting plan

Row numbers count from the start of each section. Shaping always lands on a right side row, so every wrong side row is a plain purl row. Each shaping row changes one stitch at each side and moves the count by two.
