A Guide to Measuring Circular Knitting Needles for Your Projects

circular knitting needles

Circular knitting needles are versatile tools for crafting a wide variety of projects, from hats and sweaters to blankets and shawls. To ensure the success of your knitting projects, it's crucial to choose the right needle size. Measuring circular knitting needles is a straightforward process, but it's essential to get it right to achieve the desired results. In this guide, I'll walk you through the steps for measuring your circular knitting needles accurately.

Step 1: Identify the Needle Size

Most circular knitting needles are labeled with their size, but the labels can sometimes be hard to read or may wear off over time. To confirm the size of your needle, look for the label on the needle itself. The size is typically marked in both metric (mm) and US sizing (e.g., 4.0 mm or US 6). If it is only marked with one sizing standard and you need the conversion, refer to this "Knitting Needle Size Converter Calculator".

If your circular needles lack labels or the markings have faded, you may need to measure the needle size manually.

Step 2: Measuring the Diameter

If you are unable to determine your needle size from a label, an alternative approach is to utilize a knitting gauge or needle sizer. To obtain an accurate measurement of the diameter, you must measure the width of the needle shaft while excluding the tip.

  • Select the appropriate hole on the gauge that matches the needle size.

  • Insert the needle, ensuring only the shaft (excluding the tip) goes through the hole.

  • Note the size indicated near the hole, either in metric (mm) or US sizing.

  • Record the measurement for future reference.

Step 3: Measuring the Length

Measuring the length of circular knitting needles is relatively simple:

  1. Lay the needle flat on a table or another flat surface.

  2. Straighten the cable out as much as possible without stretching it.

  3. Measure the length from the tip of one needle to the tip of the other.

This measurement tells you the length of the circular knitting needle, which is important when choosing a needle for your project. Different project types may require longer or shorter circular needles.
