Product information

This needle sizer is the perfect tool if you want to check the size of your hooks or knitting needles. Measures both metric and US needle and hook sizes from US size 0 (2.0 mm) up to US size 15 (10 mm).

The needle sizer is oblong and has a 5 inch ruler down one side and 14 cm down the other side, which is handy for measuring your stitch count or row count.


This is very useful. I have multiple of them as I usually can't find the one I'm looking for. They give great indication what size your knitting needles are - particularly if you have older models where it's not written on the needles.

I always keep a needle sizer in with my supplies when crocheting or knitting as some of my needles don’t show a size on them...with a handy sizer you will always be assured you are using the correct needle or hook size for you project.


The gauge is handy, but it's the fact that I can easily grab this and measure what I'm making seals the deal for me.
This is my companion for when I make headbands (for measuring the width).


It seems strange, but this needle sizer is something you will need if you are an avid knitter!
My needles have lost their printed number, so this needle sizer is so helpful for me!


Was given a bunch of old meddle a while ago and didn’t know what size they were. I got these in one of my orders and know I was able to know what size the needles were.
