How to Make a Gauge Swatch in Crochet (Free Worksheet + Step-by-Step Guide)
Let’s be real, friend — when inspiration strikes, the last thing you want to do is crochet a mini blanket of homework before diving into your new project. But if you’ve ever ended up with a crop top instead of a sweater, or a baby blanket that could double as a California King… you’ve already met the power of gauge.
A gauge swatch is your project’s reality check. It’s a small sample that shows how your yarn, hook, and tension work together — before you commit to the full piece. Even with the same yarn and hook, two people can get completely different results based on how tightly or loosely they crochet. I can tell you firsthand: if I’ve had too much coffee, my gauge changes faster than my yarn color changes in an ombré skein. ☕🧶
So before diving into your next blanket, hat, or cardigan, let’s take five minutes and learn how to make a crochet gauge swatch the easy way — the Marly way.

🪄 What You’ll Need
- The same yarn you’ll use for your project
- The hook size listed in your pattern (and one size up and down for testing)
- A ruler or gauge checker tool
- Stitch markers for Crocheting (optional, but helpful)
- A little patience and your BiCrafty Bestie cheering you on 💕
✨ Step-by-Step: How to Make a Crochet Gauge Swatch
Step 1: Chain and Work a Sample
- Chain a few extra stitches beyond what the pattern calls for (if your gauge is 4″, make a 6″ swatch; if it’s 6″, aim for 8″).
- Crochet in the same stitch pattern used for the project — for example, single crochet, half double crochet, or the shell stitch pattern.
- Work at least two full rows to stabilize the edge, then continue until your swatch is roughly square.
Step 2: Block (or at Least Flatten)
Lay your swatch flat and gently steam or spritz it. This relaxes the stitches and gives you a realistic measurement. 👉 Always measure after blocking, especially for garments and blankets.
Step 3: Measure Your Gauge
Place your ruler across the center of the swatch (avoid the edges — they lie to you!). Count how many stitches fit into 4 inches (10 cm) across and how many rows tall in that same section.
If the pattern says “14 dc and 10 rows = 4 in,” here’s how to read it:
- Stitches per 4”: Count horizontally across.
- Rows per 4”: Count vertically up.
🧮 Fill-in-the-Blank Gauge Tracker
| My Stitch Type | Pattern Says | My Measurement |
|---|---|---|
| Stitches per 4” | _____ | _____ |
| Rows per 4” | _____ | _____ |
If my stitch count is higher than the pattern → my stitches are smaller → I crochet tight → go up a hook size.
If my stitch count is lower than the pattern → my stitches are bigger → I crochet loose → go down a hook size.
⚡ Quick Adjustment Cheat Sheet
| My Swatch Shows… | What It Means | Try This |
|---|---|---|
| More stitches per inch | Too tight | Larger hook |
| Fewer stitches per inch | Too loose | Smaller hook |
| Same stitches & rows | Perfect match! | You’re ready to start 🎉 |
🧷 Planning Blanket Sizes (Optional)
Once you know your gauge, you can use it to customize the width of your blanket. Use this quick formula from the Shell I Make You a Blanket pattern:
- My repeat width = ____ inches
- Target width = ____ inches
- Repeats needed = target ÷ repeat = ____ ÷ ____ = ____
- Starting chain = (repeats × stitch multiple) + turning chains = ____
You can find standard measurements in the Crochet Blanket Size Chart.
