YARN & FABRIC CALCULATORS
Turn your swatch into a gauge diagnosis – see whether you run tight or loose, how to fix it, and exactly how your gauge changes the finished size.
How to measure your gauge
Work a swatch at least 6 in square in your real stitch pattern, block it, then measure in the calm center – never across the edges.
Typical gauge by yarn weight
Worsted on a 5 mm hook or needle usually lands near 20 stitches and 28 rows over 4 in – the most common starting point for sweaters and blankets.
DK runs finer, often around 22 stitches over 4 in, giving a smoother fabric for tops and baby garments.
Fingering is finer still at roughly 28 stitches over 4 in. The drape is lovely, but every stitch counts, so accuracy matters most here.
Bulky works up fast at about 14 stitches over 4 in. Small gauge slips show quickly because each stitch covers more space.
Gauge questions, answered
How do I measure gauge correctly?
Work a swatch at least 6 in square in your real stitch pattern, block it, lay it flat, and count stitches and rows across 4 in in the center – skip the curling edge stitches.
Why does gauge matter so much?
A small per-stitch difference multiplies across hundreds of stitches, so being slightly off can shift a finished garment by several inches.
My gauge is off – how do I fix it?
Too many stitches per inch (tight): go up a hook or needle size. Too few (loose): go down a size. Then swatch again.
Before or after blocking?
After blocking, because washing and blocking change the fabric. Measure the way you will treat the finished piece.
Is knit gauge the same as crochet gauge?
No – crochet stitches are usually taller and bulkier, so always swatch in the craft and stitch you will actually use.
