Converting guage from 4st/inch to 4.5st/inch

I’m knitting a nursing sweater from Natural Knits for Babies and Moms.

It calls for a yarn that is about 4 stitches per inch on size 8 needles (16 sts and 22 rows = 4").
The yarn that I have is about 4.5 stitches per inch on size 8 needles (16 sts and 22 rows = 3.5") - Here is my yarn and the swatch I made.

I don’t want to increase my needle guage - I think it will make the fabric too holey. I was thinking I could knit the large instead of the medium and get the measurements I need?

So… I tried to do some math to figure this out – If you can go over this and confirm that I’m going to knit the right size – that’d be MUCH appreciated.

I have a 38" bust. But I’m 4 months pregnant… my guess is I’ll be bigger once I deliver and start nursing (and, this being a nursing sweater, that’s when I’ll be wearing it). The bust size for a large, using my newly calculated guage would fit 38-40" bust. The finished size will be 44" – which seems kinda big… but I guess you want a loose-ish sweater?

What do you think?

I’ll leave the double check of the table to others more experienced but you may be surprised just how many inches you can increase on the bust while nursing! And then consider sometimes if you may need to use nursing pads etc also and that will ask for a little extra sizing. I would go for the 44 as long as you are sure it will be 44 and no larger as such. That’s allowing six inches and I think that a good size increase for the situation. I bet we’ll get someone telling us they needed 10" more! :roflhard:

Hi Jessica!

Amy O’Neil Houck has a fabulous template for gauging sweaters to fit. Maybe it will help you with your calculations.
