Crochet swatching

Swatching is an important step in crochet that helps ensure your finished project will have the right size and fabric feel.

What is a swatch?

A swatch is a small sample of crochet fabric made using the yarn, hook, and pattern stitches you plan to use for your project. It allows you to:

• Check your gauge (stitch and row count per inch/cm).
• Test your tension and hook size.
• See how the yarn and stitch pattern work together.
• Decide if you need to adjust hook size or yarn choice.

Why swatch?

• To make sure your finished item matches the pattern dimensions.
• To avoid surprises with size — no one wants a sweater that’s too small or too big!
• To get familiar with the stitch pattern.
• To check how the fabric drapes and feels.

How to make a crochet swatch

1. Choose your yarn and hook as recommended in the pattern or your preference.
2. Chain enough stitches to make a square at least 4 inches (10 cm) wide, preferably more (5 inches or 12 cm is even better).
3. Work the stitch pattern for at least 4 inches (10 cm) in height.
4. Aim for a swatch larger than 4x4 inches if possible—this gives more accurate measurements.

Measuring gauge

• Use a ruler or gauge tool to count how many stitches and rows fit into a 4-inch (10 cm) square.
• Count the stitches across the width (horizontal).
• Count the rows down the length (vertical).

Adjusting your gauge

• If you have too many stitches per inch (swatch is too small/tight):
  • Try a larger hook for looser stitches.
• If you have too few stitches per inch (swatch is too large/loose):
  • Try a smaller hook for tighter stitches.

Tips for swatching

• Use the same yarn and hook you plan for your project.
• Work your swatch in the same stitch pattern as your project.
• Relax your hands while crocheting for consistent tension.
• Wash and block your swatch if your project will be washed or blocked.
• Keep your swatch until your project is complete—it’s a handy reference!

What if you don’t swatch?

• Your project size may be off.
• Garments might not fit well.
• Patterns may look different than expected.
