Knitting Calculator
Gauge, Increases & Decreases
Free
Free gauge, increase, decrease and shoulder short-row tools, plus 12 crochet stitches and techniques with US/UK terms and offline steps. No account or in-app purchases.
Knitting Calculator is a free tool for knitting and crochet. Calculations work offline, with no account or in-app purchases.
Gauge calculator
Enter a measured sample length and stitch or row count, then enter your target length. See the gauge, exact count, and a nearest-whole-stitch recommendation. The result also reminds you to account for pattern repeats and edge stitches.
Even increases and decreases
Plan evenly spaced increases or decreases for one row, or across several rows. Start with a concise result, then open neutral knitting or crochet steps when you need them. Copy or share a calculation as text.
Shoulder short rows
Plan shoulder shaping with wrap-and-turn short rows. Full shoulder instructions are available in English, Traditional Chinese and Italian; in other app languages, instructions use English.
Your current drafts and unit preference stay on your device. Calculations work without an internet connection.
