How much chunky yarn do I need for a throw?

Categories: Chunky Blankets and Scarfs, Chunky Crochet, Chunky Yarn, Popular

A question I get asked a lot is “how much chunky yarn do I need for a throw?”. There are lots of different factors involved, so I’ve put together my expert knowledge and recommendations for you.


What influences how much yarn you’ll need

There are lots of different factors involved in working out how much yarn you’ll need:

  • whether you’re crocheting or knitting,
  • the size of the yarn,
  • the needle/hook size,
  • your unique tension,
  • the stitch, and
  • whether you’re feeling anxious or relaxed.


A quick guide:

I allow 6 x 300g skeins of Homelea Bliss for a 1m x 1m crocheted throw rug (knitting will use less than this), and 4 x 1kg balls of Homelea Hug for an arm crocheted 1m x 1m throw rug. Sometimes I use this as a guide, allow some extra, and just go with the flow and see what size throw I end up with.

A more accurate way to work this out: make a test piece with 1 skein or ball to work out what you’d like to make and how much yarn you’ll need – I’ve included instructions down below on how to do this below. You can always turn it into a cowl or a scarf once you’ve made your blanket.


Why not join Blanket School instead? One of the perks of your membership is that we’ll work out how much yarn you’ll need for you (and teach you how to easily work it out too).

The most accurate way to work out how much yarn you’ll need

The way I work out how much yarn I’ll need for a chunky throw is to do a gauge square with 1 skein or ball of yarn and then use some simple maths.

This is what to do:

1 – Make a square

Crochet/knit a square that’s at least 30cm (0.3m) x 30cm (0.3m). For the most accurate answer make sure you use the stitch and hook/needle size you want your throw to be made with.

2 – Weigh and measure

Weigh the square in kilograms (kg)  and measure it in metres (m).

3 – Square area

Calculate the area of the square by multiplying the length and width (both from 2 above).  For example – 0.3m x 0.3m = 0.09m2.

4 – Square weight / area

Calculate the weight per area of your square by dividing the weight (from 2 above) by the area (from 3 above). For example – 0.3kg / 0.09m2 = 3.3kg/m2.

5 – Throw size

Work out how big you want your throw to be – I allow 0.7m x 0.7m for a baby blanket, 1m x 1m for a throw and for my queen sized bed I allow 1.7m x 1.7m.

6 – Throw area

Calculate the area of my throw by multiplying the size lengths (from 5 above). For example for a throw = 1m x 1m = 1m2.

7 – How much yarn

Calculate the amount of yarn by multiplying the square weight/area (from 4 above) by the throw area (from 6 above). For example –  3.3kg/m2 x 1m2 = 3.3kg.

8 – Allow some extra

I always allow extra yarn because there’s nothing worse than being a little bit short and not being able to get more yarn in the same dye lot! I allow at least an extra 10% and I do this by multiplying the amount of yarn by 1.1 – for example 3.3kg x 1.1 = 3.6kg.

If you need to get this weight back to grams to use with Homelea Bliss simply multiply it by 1000. For example – 3.6kg x 1000 = 3600g.

There are 300g in each skein of Homelea Bliss, so to work out how many skeins divide your weight in g by 300. For example – 3600g / 300 = 12 skeins.

    Hi Lynda I have bought the wool and have been trying to find a pattern which has become difficult- as I have basic skills and just wondering if you could tell me the number of chains I’ll need to make a 1mx1m throw – I have 6 of your 300g Homelea Bliss wool and have noticed I can’t get a copy of your blanket pattern kind regards Maria

    Hi Maria,

    It’s lovely to hear from you ?

    The number of stitches for a 1m x 1m throw will depend on the stitch, the size of your crochet hook and your crocheting tension. To find the exact number of stitches I recommend following the step by step instructions in this blog post. Otherwise, try 30 stitches and adjust from there.

    My chunky blanket crochet patterns are available through Blanket School and we will be taking more enrolments later during the year.

    With love, Lynda.

    Hi I used to knit a long time ago and all I want to really do is a patch work blanket/throw with Maybe just 2 or 3 colours in chunky or super chunky wool .. I don’t know what size to do my squares or how much wool ..

  5. Lynda Rennick says:

    Hi Michelle ? You can do your squares whatever size you like. Why don’t you get a ball of yarn in the size and type that you like and experiment with what kind of squares you’d like to make. You can then use the weight of one square to work out how much yarn you’ll need to make your blanket.

    The amount of yarn you’ll need will depend on whether you’re knitting or crocheting, what size yarn you’re using, what fibre your yarn is made from, what size hook or needles you’re using, what pattern you’re making and what your unique tension is. First start by working out what squares you’re going to make, and then work out how much yarn you’ll need from that.

    I hope this helps.

    With love, Lynda.
