Gauge and tension

Gauge tells you how many stitches and rows fit in an inch (or 4 inches). You measure it in a swatch. In the UK, crocheters call this “tension.”

Gauge matters because it controls the size and fit of your finished project. Taking a few minutes to make a swatch, check it, and adjust your hook can save you time, yarn, and frustration.

• Stitch gauge = number of stitches across a set width (usually 4 inches / 10 cm)
• Row gauge = number of rows down a set length (usually 4 inches / 10 cm)

Why is gauge important?

Gauge ensures your finished item matches the pattern dimensions. Getting it right is critical for garments, amigurumi, and any fitted item.

• Ensures your finished item matches the pattern dimensions.
• Avoids projects that are too small or too big.
• Helps with consistency when using different yarns or hooks.
• Critical for garments, toys (amigurumi), and fitted items.

How to check your gauge

Crochet a 4”x4” (10x10 cm) swatch using your pattern yarn and hook. Measure stitches and rows within that square, then adjust your hook if needed.

1. Use the yarn and hook recommended in the pattern.
2. Crochet a sample swatch, usually about 4”x4” (10x10 cm).
3. Lay your swatch flat (don’t stretch).
4. Measure stitches and rows within the 4” square.
5. Adjust hook size if your gauge is off:
   • Too many stitches = use larger hook.
   • Too few stitches = use smaller hook.

Tips for consistent tension

Hold your yarn comfortably and practice even stitches. Using the same hook type and size throughout helps maintain consistency.

• Hold your yarn comfortably, not too tight or loose.
• Practice stitches evenly.
• Use the same hook type and size throughout.
• Avoid changing tension mid-project.
• Wash and block your swatch to see true size.

Example swatch chart

Gauge	Stitches (per 4”)	Rows (per 4”)	Hook Size (mm)	Yarn Weight
Pattern gauge	16	20	5.0	DK (Light)
Your swatch	18	22	5.0	DK (Light)
Result	Too tight	Too many sts	Try larger hook

Problem	Solution
Too many stitches	Use bigger hook
Too few stitches	Use smaller hook
Rows too tall or short	Adjust tension or hook size
Inconsistent tension	Practice and relax hands
