What’s A Knit Needle Gauge?
Knitting needle gauges are flat with holes in varying sizes. The holes are marked with the size of needles. Most knitting needle gauges have US and Metric sizing to use the holes to measure the size of a knitting needle. They’re an inexpensive tool and handy. Needle gauges are combined with a knitting gauge ruler.

How To Use A Knitting Gauge Ruler
Grab your unmarked needle and poke it through the holes. Have a small needle? It might fit the US size 1 hole. If the needle doesn’t slide through the hole, size up. The knitting needle needs to slide through without extra space.
Here’s an example. A needle might be US 4. When I slide it through the size 4 hole, it goes through with space to spare. I go down one size. When I put it through the size US 3 hole, it slides through the hole, but there’s no room between the needle and the hole.It’s a size US 3 needle.
When I tried the size US 2 hole, I couldn’t get the needle to go in past the needle tip, so US 3 was correct. However, knitting needle companies have differences.

How To Tell Knitting Needle Size
Knitting needles are measured by their diameter – the line segment through the center of a circle. To measure some of your knitting needles, you need a ruler with the metric system and my needle conversion chart.
Measure the diameter of your needle, place it between the # marks on your ruler, and count how many lines it falls between. One centimeter is ten millimeters. This method is difficult, but it’ll do.
Here’s my helpful size chart.
How To Measure Circular Knitting Needle Size Without Gauge
The needle tips between the cord of your circular needles are measured by diameter. Use the tips I discussed for straight needles earlier in the post for circular knitting needles too.
Clever Ideas For Labeling Your Needles
Use a small piece of tape with the size marked in pen. Get beautiful washi tape to add interest to your needles. This is best with single pointed or straight needles and the tape on the knob.
If labeling Double Pointed Needles, fixed circulars, or interchangeable tips in your needle set, use nail polish colors. Dash polish on an index card and note what size it is.
Have multiple needles of the same size? Bundle them with a rubber band and label. A fabric needle holder is excellent when you label the slots.
