Knitting needle sizes

Knitting needle sizes refer to the diameter of the needles, affecting the size of the stitches and the finished fabric. They are measured in different systems: US sizes (e.g., US 8), metric millimeters (e.g., 5mm), and UK sizes. Larger diameters (e.g., 10mm) create looser, more open stitches, ideal for chunky projects, while smaller diameters (e.g., 3mm) produce tighter, more detailed fabric. Choosing the right size depends on your yarn thickness and the desired fabric texture. Always match the needle size to the yarn’s recommended gauge for the best results.
