One of the most useful tools a knitter has is the knitting needle gauge, which is a tool for measuring the size of a knitting needle. There are various styles of gauges available for sale, and in this post we're going to have a look at some of them.
The Knitter's Rule handcrafted bamboo gauge above is probably one of the cutest I've seen, but sadly for those of us who might want one, the Etsy seller who made the Knitter's Rule gauges has retired from Etsy.
This is the utilitarian and widely available Susan Bates needle gauge. It's the one I have, and though it may be unexciting aesthetically, it could hardly be bettered in terms of its utility. The built-in rulers and gauge measure are very handy, and besides providing both metric and U.S. knitting needle sizes, it also measures crochet hook sizes, and as it's made of metal it's extremely durable. My one quibble is that it doesn't have U.K. needle sizes on it, but then no gauge that I've seen has all three.
These owl and Dr. Who-themed gauges are made by the Etsy vendor Tangerine Designs, who also makes gauges in sheep and hedgehog shapes. They aren't quite as useful as the Susan Bates gauge because they only have either metric or U.S. needle sizes and have little measuring capacity, but they are undeniably adorable.
This laser cut plastic Swift needle gauge was made by Etsy vendor Hipstrings. There are a lot of handmade and vintage gauges for sale on Etsy, so it's worth a browse through their listings if you'd like a gauge that is styled like your spirit animal or favourite theme.
Malojos.com offers those of us who feel married to our knitting this sterling silver needle gauge ring, which measures knitting needle U.S. sizes from 0-8.
Of course, if knitting needle gauges are too old school for you, there is an app for that.
