How much yarn do I need?

It’s a question every crocheter asks… how much yarn do I need? And what if I change the thickness of yarn?

Today, I’ll show you how to calculate how much yarn your project will need… no more guessing!

Discover your yarn + hook combo

The only way to know for sure is to calculate how much yarn each stitch (using your yarn and hook) takes. Using some yarn and hooks I had on hand, I did few examples:

How much yarn do I need crochet

As you see, the thicker the yarn (and the bigger the hook), the more yarn you’ll need.

Your calculations may be different depending on your exact yarn and gauge… but this should give you an idea!

How to calculate the total for the pattern

To find out the total amount of yarn you’ll use for your project, multiply the number of stitches in your pattern by the number of inches each stitch uses.

Let’s take Jay the Bird as an example. The pattern contains the stitch count at the end of each line.

Adding those up gives me a total of 1656 stitches.

How much yarn do I need if I want to crochet him in a fingering weight yarn?

46 yards! That’s less than the 85 called for in the pattern because fingering weight yarn is smaller, and the project needs less!

Calculate away!

Using this method, you can calculate how much yarn a project will require with any weight yarn and hook! No more guessing!

    What a great strategy! Thank you so much for putting this together, Stacey! I love the colorful visuals.

    I crochet very tight. When a pattern calls for a set hook size to make gage I must use a larger hook, even when using the same thread. Help!

    Awesome! Thanks for figuring all that out! :)

    When I first read the title in my head I was thinking, lots and lots, (inventory) Yikes! I hope there’s someone else that thinks like me. Thanks for the practical information. I struggle with that all the time, especially with small stash buster projects.
    Cheers!

    Thank you so much for this. I have many times when I use a different yarn than is called for in the pattern. I have always used guesstimates, but this gives me a strategy so I don’t run short or have so much extra all of the time.

    This is fantastic, I have to book mark it. I also really love the visual with the colors and clean look of your blog.

    As I live in Australia, this comes in handy as I have a mountain of wool and cottons to use up and until now have been finding it difficult to work out the ply etc to do your patterns. Thank you for this page.

    Have to bookmark this one! Your instructions are so gorgeous – so easy to read and understand.

  11. Maria says:

    Great idea!
    And a perfect reason to dig up (and modify) the program I’ve written to calculate the number of stitches in a pattern.

    I love to read your blog. You have lots of wonderful ideas and very helpful. I am very new to crochet. Can you please tell me what it means by “inches per stitch”? What is the stitch? Sorry if I sound ignorant but if I don’t ask I will never know!! Thanks for your help. Connie (Perth Australia)

    Is this calculation for sc (British dc) only? Meaning that adjustments need to be made for hdc, dc and tblc?

    • Stacey says:

      Actually, this calculation is only for *my crocheting of an sc*. You will need to do your own calculations not only for the other stitches, but for your own gauge! This is just an example :)

  14. Michelle says:

    Does this go for any pattern? I’ve got one that doesn’t tell you stitch number at the end of each row or the number of rows you will end on. Just measurements in inches.

    • Michelle says:

      It also isn’t solely sc either.

      • Stacey says:

        These measurements are only representing my single crochet stitches… for an accurate measurement, you would want to calculate these measurements for your particular gauge, as everyone crochets differently. You would need to do the same thing for each type of stitch you want to use.

    • Stacey says:

      If your pattern doesn’t tell you the number of stitches at the end of each row, then that is something you need to calculate to use this technique.

    Hi! There’s a typo in the post – under the “how to calculate” section you have “multiply the number of stitches in your pattern by the number of stitches each stitch uses.” instead of “the number of inches each stitch uses.”

    Im trying to figure out how much crochet thread I will need for a filet crochet project. The only instructions on the graph is 85 X 61. This is blocks. I am using size 10 crochet thread. Do you know approximately how much thread I will need? Thank you for your help
