40I want to calculate my gauge

Convert between stitch counts, measurements, and pattern gauges

What is gauge? Gauge (also called tension) is the number of stitches and rows in a standard measurement — typically 10 cm (4″). Every knitter and crocheter works at a slightly different tension, so your gauge determines the final size of your project. A pattern that says “20 sts = 10cm on 4mm needles” is telling you the fabric density it was designed for.

Why does it matter? Even one stitch per 10cm off can add several centimetres to a sweater. If your gauge is tighter than the pattern, the piece comes out smaller; if it's looser, it comes out larger. The gauge calculator helps you measure, compare, and adjust before you commit to a full project.

Measure Your Swatch

Gauge Calculator showing swatch measurements and adjusted stitch and row counts

Navigate to Tools → Gauge Calculator. Enter how many stitches and rows you counted, and the width and height you measured over.

Tip: Knit a swatch larger than 10 cm × 10 cm, then measure a section in the middle — edge stitches are often distorted. Block your swatch first for the most accurate result.

Read Your Results

The calculator converts your raw count into a standardised gauge. For example:

You counted: 24 stitches over 12 cm
Your gauge: 20 sts / 10 cm

It does the same for rows, so you get both stitch gauge and row gauge in one step.

The result updates live as you type. No need to press a button — change any number and the gauge recalculates instantly.

Compare to Pattern Gauge

Enter the pattern's recommended gauge to see how yours compares. The calculator shows the difference and suggests needle size adjustments: go up a size if your gauge is too tight (too many stitches), or down if it's too loose (too few stitches).

Tip: Changing needle size by one step usually shifts your gauge by 1–2 stitches per 10 cm. If you're far off, try a jump of two sizes and swatch again.

What the Difference Means

Matching gauge exactly? You're good to go — cast on with confidence.

Off by half a stitch? Usually acceptable for most garments. Consider swatching once more to confirm.

Off by 1+ stitches? The finished piece will be noticeably different in size. Change your needle size and swatch again before starting the project.

Row gauge off but stitch gauge correct? This is common. Most patterns give length instructions in centimetres rather than row counts, so stitch gauge is usually more critical. Adjust row counts if the pattern relies on them.

Convert Between Units

Switch between metric (stitches per 10 cm) and imperial (stitches per 4″) with a single tap. The calculator handles the conversion automatically, so you can work in whichever system your pattern uses.

Note: 10 cm and 4 inches are close but not identical (4″ = 10.16 cm), so gauge numbers differ slightly between systems. The calculator accounts for this.

Quick Reference: Standard Gauges

Not sure if your gauge is in the right ballpark? Here are typical stitch gauges per 10 cm for common yarn weights:

Lace: 32–40 sts
Fingering: 28–32 sts
Sport: 24–28 sts
DK: 20–24 sts
Worsted: 16–20 sts
Bulky: 12–16 sts
Super Bulky: 8–12 sts

These are guidelines — every yarn, needle, and knitter combination is unique. Always swatch.
