iKnit Needle Sizer takes the place of a standard needle gauge to find the size of a knitting needle or crochet hook. 

iKnit Needle Sizer can size knitting needles from 1.75mm (US size 00) up to 25mm (US size 50) and Crochet hooks from 2.25mm (US B/1) up to 19mm (US size S) with a precision of + or - .078mm (.003 inches) limited only by the resolution of the screen.

No other single needle gauge can accommodate the range of needles and hooks that iKnit Needle Sizer can. 

All you need to use it is your iPhone/iPod Touch (IPad app ready soon!) and the needle or hook you want to size.

Customer Reviews

I love this app

I have so many needles that don't have the size printed somewhere on the needle, and others that had the size printed on it, but the printing has gotten rubbed off. I do have the "old" needle sizers, but who in the world can keep up with those things... they are never where you need them, when you need them, so you either guess or spend time searching for the gauges. NO LONGER... I always know where my Touch... click on the Needle Sizer app, and check the needle. Quick and easy! This is one great app... Five stars from me! <><

The needle gauge you can't lose!

This works great on my iPhone. It sizes all the tiny (sock) metric sizes, which not all physical needle gauges will do. It's part of my phone, so always with me (so I can't lose it, unlike all those other little gauges I have).
It seems like someone should be able to make a passive one - where you'd put the needle on the phone and it would sense the size ... maybe some future iteration of the app.
In the meantime, I love it.

Useful but takes some getting used to

I have the knit picks interchangeable needles and the knit picks sock needle kit. None of them have any sizes printed on them, and my metal gauge does not include 2mm, 2.25mm, 2.5mm, 2.75mm, 3mm, or 3.25mm (it's lost, anyway), but this app does! It saved my life when I spilled all the sock needles on the floor and they got all mixed up. It took some getting used to with the smaller sizes (is it covering the red line or not?) but I got the hang of it and now all my needles are in order, thank goodness. Love this app! Great idea!
