Length of circular needles?

Hello, I am trying to find information on the needle lengths for the Birkin sweater pattern. The pattern only seems to specify the needle sizes. Thanks for any suggestions!

Hi there.

Which Birkin sweater are u making? There are 3 patterns called Birkin on Ravelry.com.


It depends on the type of sweater. A raglan will be knit all around unless it buttons in the front. A regular sweater will be knit front, back, and sleeves then sewn together. I’m thinking a 40 inch? Circulars can be expensive buying one at a time. This might be the time to get that interchangeable set you’ve been looking at. Some of my fixed circulars ran $18-25 apiece. The set was like $60. They have a connector piece that you can connect as many cords as you want to make it any length. Two 24s, two 32s, etc. Some sets come with a 40 inch. You will have to read product description carefully.

Thanks for your suggestions- I will check them out

Welcome to KH!
Here a chart that may help with estimating the number of sts that will work on a given circular needle. The chart is about halfway down the page.

I have that sweater on my list of favorites. Looking forward to hearing how it goes and to seeing a photo when you finish.

Hi - what a great chart! Thanks a lot for sharing. Yes I hopefully will be posting the finished sweater in the future, as so far I have never tried something so complicated…
