Calculating Gauge

 

The gauge that is mentioned on patterns represents the number of stitches and rows that result from the specified yarn, hook and main stitch of the pattern.  This is usually represented as the number of stitches / number of rows in a 4 inch by 4 inch (10 cm x 10 cm) piece of work.  

Since everyone crochets a little bit differently (some tight and some loose, and a lot in between), the measurements of individual work can vary greatly, even when using the same hook size and yarn that the pattern specifies.

To save some time, I calculate gauge the following way:

1. Chain 10 + 1, turn

2. Make 10 rows in specified stitch

3. Measure Length in Inches (represents stitches) - Represented by x.

4. Measure Height in Inches (represents rows) - Represented by y.

Once you have those two numbers you can use the Excel Sheet linked here:

Or if you prefer to calculate yourself (calculator recommended to save a headache):

10 divided by x = length of each stitch; Multiply that number by 4 = number of stitches in 4 inches

10 divided by y = height of each row; Multiply that number by 4 = number of rows in 4 inches

*I would recommend rounding up to the nearest whole number

Don't cut off the yarn in the sample you made, you can simply frog it and use it for your project.

Adjustment to Match Gauge:

If you find that your gauge is not matching the author of the pattern's written gauge, your project may not come out to the correct size.  This may not matter as much in some projects (like dishcloths), but with clothing gauge is really important to follow.

If you have TOO MANY stitches = INCREASE Hook Size

If you have TOO FEW stitches = DECREASE Hook Size

You can adjust your tension as well if the adjustment needed is not huge, but I recommend crocheting with your normal/what is comfortable for you and adjusting the hook sizes.

Keep in mind not all brands have the same dimensions - they may both say 5.00mm, but there may be slight differences between brands.  That being said, make sure you keep the same hook throughout the project, because if you change brands half way through it is possible it will be a noticeable change in the final project.
