Crochet Gauge Calculator — Stitches & Rows Per 10cm

Make a swatch at least 15cm x 15cm. Crochet fabric can curl or distort at the edges, so a larger swatch lets you measure the central 10cm accurately. Use the same stitch, hook, and yarn you plan to use for your project.

Yes, significantly. Double crochet (UK) / single crochet (US) produces shorter, denser rows. Treble crochet (UK) / double crochet (US) produces taller, more open rows. Each stitch type will give different row gauge even with the same hook and yarn.

Crochet gauge varies more between individuals because the single hook technique allows more variation in yarn wrapping tension, loop height, and insertion point. Always swatch and adjust hook size until you match the pattern gauge.

Yes. Wash and block your swatch the same way you will care for the finished item. Crochet fabric often relaxes or changes shape after washing, especially with natural fibres. Cotton tends to grow; wool may felt if agitated.

For stitches, count the V-shapes along the top of a row. For rows, count the horizontal ridges or chain spaces up the side. Place markers at the start and end of your counting area to ensure accuracy. A ruler or gauge tool helps maintain consistent measurement.
