Why Gauge Matters

If you’ve ever ended up with a sweater two sizes too big, or a hat that fits a doll, you know the consequence of skipping gauge.

 

Gauge may sound technical or boring, but it’s actually your best friend. It’s the factor that determines whether your knitting will have the fit you dream of.

 

 

What is gauge?

 

Gauge simply means how many stitches and rows fit into 10 cm of your knitting.

 

A pattern might say, for example: 21 stitches x 28 rows = 10 x 10 cm on 4 mm needles.

 

If your yarn or knitting tension is looser or tighter than that, the entire project changes.

Why does it matter?

 

• Size changes: One extra stitch or one less per 10 cm can mean several centimeters difference across a sweater.
  
  

• Fit is off: A cardigan meant to be oversized could end up tight - or the other way around.

• Yarn amount won’t match: Looser knitting uses more yarn; tighter knitting might leave you with leftover yarn or too little.

How to test your gauge

 

1. Cast on more stitches than the pattern calls for (e.g., 30 instead of 21).

2. Knit a swatch at least 12 x 12 cm.

3. Wash and lay flat to dry - fibers change after washing.

4. Measure a 10 x 10 cm square in the middle and count stitches and rows.

5. Adjust needle size up or down until you match the pattern’s numbers.

What if your gauge doesn’t match?

 

• Too many stitches: Switch to larger needles.

• Too few stitches: Switch to smaller needles.

• Exact match: Perfect - start knitting!

 

It may take one or two tries, but it’s worth it.

 

 

Real-life examples

 

• A sweater written for 21 sts/10 cm: if you get 23 sts instead, it will be ~8 - 10 cm narrower in circumference.

• A hat written for 22 sts/10 cm: if you only knit 20 sts, it will be too loose and won’t fit properly.

 

Small differences on paper = big differences in your wardrobe.

 

 

FAQ about gauge

Does this apply to shawls or blankets?
Yes, especially if you want the correct size and yarn usage.

 

Should I always wash my swatch?
Yes. Fibers change after washing and drying - especially wool and cotton.

 

Can I use a different yarn if the gauge matches?
Often yes. Also check yardage and fiber type to ensure the drape and appearance are similar. Cotton vs. Wool – Which Yarn Should You Choose?

 

Is gauge more important than the yarn brand?
Yes! Gauge ensures fit; the brand is secondary.
