How much yarn do you need for a Mitered Square

If you have ever contemplated the size of your leftover yarn bag and thought of making a mitered square blanket, then this is a post to bookmark and come back to for reference.

Ever obsessed with using up my leftover yarn - which mysteriously keeps replenishing itself when my back is turned, I took it upon myself to do a little investigation and work our how much yarn I needed for mitered squares of varying sizes in both DK and sock weight yarn.

The results I present below for your knitting pleasure because as we all know, the only thing more frustrating than running out of yarn with just a few rows to go, is ending up with lots of slightly smaller balls of yarn (that are too small for the square size you’ve chosen).

I have to add the caveat here that YMMV - your mileage may vary.

I weighed these squares on my digital scales which only go down to 1g increments so there may be some rounding up/down. Also your gauge and specific yarn weights might give different results, but hopefully the amounts below will serve as a guide.

Yarn amounts for sock weight yarn:

Using a 3mm needle and at a gauge of 28sts per 4”. In the list below 10x10 is shorthand for 10 sts by 10 sts.

10x10 1.5" less than 1g
15x15 2" 2g
20x20 3" 4g
25x25 3.75"6g
30x30 4.25" 8g
35x35 5.25" 11g

Yarn amounts for DK weight yarn:

Using a 4mm needle and at a gauge of 21sts per 4”

10x10 2" 2g
15x15 3" 4g
20x20 3.75" 8g
25x25 4.5" 14g
30x30 5.5" 18g
