🧦 Sock & Bootie Size Grader

Step 1 · Add your pattern

Text-based PDFs work best; for scanned PDFs paste the text instead. Everything runs in your browser.

Tips: start each part with a heading line (e.g. SOLE, TOE, FOOT, HEEL, SIDES, LEG, CUFF, STRAP). Tag a stitch multiple on its own line like [multiple of 4 + 1]; it applies until [multiple off] or the next tag. Write decreases as stitch counts (e.g. sc2tog over next 12 sts) if you want them graded too.

Step 2 · Choose the size you made and the sizes you want

Select your base size (the size you crocheted) and tick every size you want written out. These are typical bare foot measurements and are fully editable. If you know the actual foot, measure it: foot around is taken at the widest part of the ball of the foot, foot length is heel to longest toe, and leg height is how tall you want the cuff or leg from the floor/heel. Teens usually fit the women's or men's rows.

The scaling comes from the size chart (same yarn, same gauge). Gauge and ease are only used for the stitch-count cross-check in the results. Snug socks usually use about −10% ease (smaller than the foot); booties and slippers usually use 0% to +10%.

Step 3 · Options & section adjustments

Each section chooses which measurement drives its stitches and rows. By default SOLE uses foot length for stitches and foot width for rounds. For booties, the sides, toe and instep are worked around the sole, so they follow foot length too. For socks, TOE and HEEL use foot around, and FOOT uses foot around and foot length. In both, LEG, CUFF and ANKLE use ankle and leg height; CALF and KNEE use calf; STRAP uses ankle and isn't lengthened. Change any of them below.
