Embarrassing Math Question

Hi everyone! I need some math help here. I am knitting a scarf in 1x1 ribbing for my husband out of some really gorgeous, really tiny yarn (Rowan Felted Tweed), and, despite being 30" into it, I have just now realized that it is WAY too narrow. I’m going to have to frog it, and this will make the second time (first time was because this was only my second knitting project, so I had some mistakes that were too far down to fix w/o frogging), so I’m about to cry, but it must be done!

Here’s my problem. I only have 3 skeins of this yarn (I got it in London last summer, which explains why I can’t get more of it in the same dye lot). The scarf needs to be about 60". So I need each skein to last for about 20". Right now the scarf is 6" wide (I know, WAY too narrow for a guy) and the first skein lasted for 27".

So my question is, how wide can I make it for each skein to end up around 20", or how do I figure that out? I can figure out stitches to the inch after that, but this has me stumped. I’m sorry for the silly question, but I’m a liberal arts major for a reason! Thanks in advance for any help!

What I do is figure out how many inches another 4 sts would make (probably 1 in this case) and multiply by the length, then divide by the new width and subtract that from the current length. So for example… 1x27 is 27 sq inches, divided by 7 (the new width) is 3.85 inches, call it 4, so that would leave your new length at 23". So you could add another 2 sts - 6 altogether (hypothetically 1½") and it would still be about 22". You could also go up 1 needle size or 2, add 4 sts and it would be both wider and still give you enough yarn for the length you want.

Thank you!!! That really helps and it’s surprisingly simple! =) So if I add 2 inches to the width (and you’re spot-on about the gauge), that will take off 6.75" in length, leaving each skein at 20.25" in length. Perfect! So I just add 8 stitches in width!

I had thought about going up another needle size, too, but it’s already pretty loose. I think if I go up any more I’ll have lace! =) Thanks so much for your help!

yay! It may be only an estimate, not spot on, but I think it should be close enough. It’s sort of translating the measurements into square inches.
