Instant gauge math for knitters!

Three easy-to-use options:

Adjust a Pattern — Converts stitch and row counts from the pattern's gauge to your new gauge. Takes repeating patterns into account if you wish.

How Much Difference Will It Make? — Tells you exactly how much bigger or smaller the project will be if you just knit it as written, but in a different gauge.

Work from Measurements — Effortless calculations of stitch and row counts from finished measurements. Takes repeating patterns into account if you wish.

Knittrick works in inches or centimeters and happily handles repeating patterns which require whole repeats of any stitch or row count. The ultimate knitting notion.

I am an avid knitter myself and have designed this app from the ground up to be as useful as possible. Please email me with any questions!

Took a while to figure out

I like this app although it took me awhile to figure out how to use it. Still don't understand the "repeats" part of it. Might make more sense once I'm more familiar with knitting.

Love this app

I love this app. Easy to use and accurately adjusts a pattern when using a different weight yarn or from just using gauge and measurements. I have used it with many projects and do not know what I would do without it! Highly recommend it, so worth the $5!

Never Not Knitting ,


This app is well written and though pricer than we knitters are used to paying for our apps it is worth every penny. It does not try to do it all but it does one thing well. It calculates the number of stitches to cast on if you use a pattern and want to change the size to match your own gauge to use a different size yarn, to change the size of the pattern in inches, or for whatever reason. And it does it instantly. Great help within the app itself and outstanding customer service.
