Pattern Requirements

Crochet patterns usually include the suggested hook size to achieve the correct stitch gauge and final project dimensions. Following these recommendations ensures your work matches the pattern’s intended design, saving time on adjustments or corrections.

Your Crochet Style

If you are crocheting closely, you may wish to change to a larger hook head to increase the size of your stitches. In case you learn that you are using big stitches, you may wish to consider changing to a finer hook for increased tension. Adding, changing, or subtracting stitches allows for control of personal style while preserving the appearance and quality of the stitches used.

Check the Yarn Label

Test Your Gauge

Change to a smaller or larger hook if your stitches are too tight or too loose.

How to Measure a Crochet Hook?

First, you need a crochet gauge ruler. The tool has holes of different diameters to fit the diameters of various crochet hooks. Using the gauge ruler will help you determine precisely what Size your hook is and ensure you use the right hook for your project.

Check the Hook

Before measuring, check your crochet hook to see if it has size markings. Some hooks have stamped or printed sizes. If there is no clear indication of its size, then it is the perfect time to measure it using a gauge ruler, knowing that you need the exact size for your project.

Insert the Hook

Place your crochet hook’s shaft through the holes in your gauge ruler from the biggest to the smallest. This way, you get a measurement where one hole closely matches your hook’s diameter, so you would not go for anything smaller. 

Finding Your Best Fit

Keep testing the hook by inserting it into every hole until you find one whose hole fits snugly, neither tight nor loose. The correct fit will be the hole matching the hook diameter closely and comfortably.

Note the Size

Once the hook fits perfectly into a hole, check the Size written next to that hole on the gauge ruler. This number represents the crochet hook size. Note this site for future reference and use it for your crocheting projects.
