Fine Weight Key Facts

Fine Weight Facts

What Weight Number Is Fine Weight Yarn?

It’s weight number 2 on the yarn weight chart.(1)

What Are Fine Weight Yarns Made From?

It’s usually made from natural fibers like wool yarn, merino wool, cotton yarn, and linen or dyed yarn, or synthetic fibers like acrylic.

Why Use This Yarn Weight?

Fine weight yarn is perfect for projects where you want more texture and drape than with worsted weight yarn. But you don’t want to go as thin as a lace-weight yarn. It’s also perfect for summer garments because it won’t be too hot to wear.

What If It’s Held Double?

If you hold two strands of fine weight yarn together, it knits up as a DK weight yarn.

Uses For This Yarn

It’s most often used for baby items, summer tops, and other garments where a lighter weight yarn is desired. Here are other projects to try using this fiber: thick socks, accessories, knit sweaters, scarves, shawls, lightweight afghans, clothing, warmer items for fall, or hats. I don’t recommended making blankets.

What Knitting Needles To Use

  • US Needle Size -3 – 5
  • For those of you in Canada, the UK, Australia and New Zealand – 3.25 – 3.75 mm

Note: The above are guidelines only. Always do a gauge swatch before starting a project using a fine yarn weight.


If you’ve run out of fine weight yarns or can’t find it, here’s what to use instead. For a finer gauge, use super fine weight yarn or fingering weight yarn.

For a thicker gauge that’s slightly heavier, use:

  • Light worsted weight yarn
  • DK weight yarn

My previous article is sock weight yarn and next up in the series is what is sport weight yarn.

I don’t recommend it for a blanket, as it’ll be very thin. You could try holding two strands together to make a DK weight yarn, but that uses twice as much yarn.
