Perfect Crochet Sweater Sizing is something we all want - there's nothing worse than finishing a beautiful crochet top and realizing it doesn't fit!
Lindsey Stephens is an expert on crochet tech editing, sizing, and grading, and makes many of us designers look good. So I'm excited to have her share her knowledge on sweater sizing here on Moogly!

Getting Started
After working on scarves and shawls and maybe even hats, everyone decides to make a crocheted garment.
When you crochet a garment, like a vest or a sweater, you have to decide what size to make. The quickest way to do that is to look for the bust or chest measurement.
What is the bust or chest measurement?
The bust measurement is the circumference of the garment at the bust. If the front measures 20 inches wide at the bust and the back also measures 20 inches at the bust, the garment’s bust measurement is 40 inches.
Many patterns will state the bust measurement upfront. For kids and men, they tend to call this chest measurement. So a kid’s sweater pattern might say something like:
Chest: 23 (25, 27) inches
That means the smallest garment is 23 inches around at the chest. The next size is 25 inches around, and the last size is 27 inches around.
If the pattern states the width of the chest, then you just have to multiply by 2 to get the garment’s chest measurement. So, if the pattern says “19 inches wide at chest” then the total measurement around the chest, also called the circumference, is 38 inches. That’s 19 x 2.
(The stickler in me has to point out that the measurements in a garment pattern are useless if you don’t match the stated gauge.)
Picking a Size
Using a tape measure, you can measure around your own chest, to find your chest circumference. Keep in mind that is your body’s measurement. You probably don’t want the sweater to be the same size. You want some room to move and, if you’re like me, maybe hide a love handle or two.
Wait. There’s More!
So once you know what bust size to choose you’re done, right? Not quite. When designers make garments they need to use a lot of body measurements. Sometimes as many as 5 or 6 different measurements can factor into designing one garment. Where do they get all those numbers? Designers refer to standards charts, like this one from the Craft Yarn Council.
These charts provide the body measurements that designers turn into garment measurements. It’s a complex process. That’s why I wrote the ebook Body Basics: A Primer on More than a Dozen Body Measurements for Knit and Crochet Garment Design. I wanted to simply the process by making it clear which measurements matter.
The Craft Yarn Council chart says a woman with a bust of 36-38 inches, will have an upper arm that is 11 inches around. However, each person is unique. So if your bust is 38 inches around, you might find that your arms are only 10 inches around. That can influence what size you make or if you make adjustments to the pattern as you go.

Hi I'm new to crochet and I have seen a tutorial for a pullover I'd like to make. I am large busted and wondering if the front panel should be bigger than the panel, or should they be the same?
Thank you
Tamara Kelly
It could be! Usually the back panel, if anything, is a little wider. But of course, we're all built a bit differently! My best advice is to try it on as you go - and never weave in your ends until you're *sure*! 🙂
