Knitting Gauge Calculator
Use your swatch and target size to calculate stitches and rows, or convert pattern counts to your gauge. Adjust the stitch count to a repeat. Every feature is free.
Your gauge
Knit a swatch and count the stitches and rows across the length you measured, usually 4 in in the middle.
One stitch is 4.6 mm wide × 3.4 mm tall
Stitches are not square, so width and height are worked out separately.
Use this when ribbing or a stitch pattern repeats. Example: 2×2 rib plus 2 edge stitches → multiple of 4 + 2.
- Cast on
- 110 sts
- Actual width 20.0 in
- Rows to knit
- 180 rows
- Actual length 24.0 in
Three quick steps
Measure a swatch
Knit a swatch with your yarn and needles, then count stitches and rows and record the measured lengths, commonly 4 inches or 10 cm.
Pick a calculation
Get stitch counts from a size, a size from stitch counts, or convert a pattern to your gauge.
Note it down
Write the cast-on and row counts on your pattern and start knitting.
Frequently asked questions
Common questions from knitters working out gauge for the first time.
What is gauge and why does it matter?
Gauge is how many stitches and rows fit in a measured length, commonly 4 inches or 10 cm. The same yarn and needles knit up differently for different people, so you need your own gauge to work out the stitch and row counts for the size you want.
How do I knit and measure a gauge swatch?
Knit a square at least 6 inches (15 cm) wide with the yarn and needles you will use. Wash or block it, lay it flat, and count the stitches and rows across the middle 4 inches. Leave out the edge stitches, which stretch or pull in. If you measured a different length, just enter that length.
What if my gauge does not match the pattern?
Changing needle size to match the pattern gauge is best. If you cannot match it, use "Convert a pattern" to turn the pattern stitch and row counts into numbers for your gauge. For patterned pieces, adjust the result to fit the stitch repeat.
Why enter a stitch repeat?
Ribbing and stitch patterns need a stitch count that is a multiple of the repeat, or they break at the edge. For 2×2 rib with 2 edge stitches, enter "multiple of 4 + 2". You get the closest count to your size plus the next option.
Does it work for crochet?
Yes. Enter your crochet stitches (for example single crochet) and rows per 4 inches the same way. When you start with a chain, add any turning chains your pattern needs to the stitch count.
Can I use centimeters?
Both cm and inch are supported. Switching units converts measured lengths while preserving your gauge and results. 10 cm is about 3.937 inches; 4 inches is 10.16 cm. Pattern counts are also converted when changing their standard 10 cm / 4 inch reference.
