Making my own needles

Can anyone tell me what size dowel makes a size 19 knitting needle?

size 19 is 15mm.

15mm is is about .59 inches.

a good knitting needle chart is at it will tell you sizes in mm.

Welcome to KH!
Yes, 0.59 inches and that’s the diameter of the dowel you’ll need.

Thank you for the reply, I will look at those links. If I were to put a dime, nickle, or quarter on the end of the dowel, which would be the closest do ya think?

A dime is about 17.9mm so that’s just a little bigger than the diameter you need. Smoothing down with sandpaper might just do it.

Fantastic! Thank you. It would be wise of me I suppose to learn more about measurements…the humor of a new knitter.

I think a 5/8" dowel will give you what you want once you sand it down. A 9/16 would be just a hair too small, I think. Ah, here…

15 mm is 19/32", 5/8"=20/32", so by the time you get your dowel sanded smooth and waxed it should be just right.
