The Master Arm Knitting Question!

How much yarn do I need for a specific sized chunky knit blanket?

… this post contains affiliate links for your convenience…

To make things SUPER easy for you I’ve put together a chart that should answer all your questions.  However I must stress that this is a general guideline. 

Everyone’s arms are different sizes and wool roving itself is different thicknesses which will result in slight differences from blanket to blanket. 

But all this being said here is the 

Let’s go!

Here are some pictures of a few of the sizes mentioned.

Want to know where I buy my wool? 

I get my wool roving directly from THIS woollen mill.

Here’s some great synthetic yarn alternatives to wool.

Red Hearts Irresistable Yarn is a great choice, and is an acrylic/nylon blend.  Super hand if you’re allergic to wool.  Click the picture to go there.

Michaels craft stores in North America carry Loops and Threads which also works great for arm knitted projects, just use 2 strands at a time and you’ll have a gorgeous blanket!

The Hobby Lobby (also in North America) carries this brand that many people have raved about, however some have complained that it sheds.

So how many skeins/balls of Chuncky yarn for a medium blanket? I don’t understand the whole lbs & cm.

    Stacy · January 10, 2018 at 5:08 am

    Hi Cindy, skeins and balls all have different lengths of yarn in them. You’ll need 120 meters of yarn or 131 yards of yarn. I hope that helped!

    Happy Arm Knitting,

Hi Stacy
How many stitches to cast on for a 72×96
Arm knitted blanket
Thanks Stacianne

    Stacy · February 1, 2018 at 8:45 am

    Hi Stacianne,
    You’ll probably need between 25 to 30, but it greatly depends on the size of your arms and you may need more. Start by chaining 25, then measure how long your chain, the length of your chain determines how wide your blanket will be, and obviously how many rows you knit will determine the length. I hope that was helpful!

    Happy Arm Knitting,

      Stacianne · February 1, 2018 at 4:37 pm

      Thank you Stacy yes this helps as I’ve never knitted anything in my life this will be an experience of a lifetime?

If making a 40X60 blanket and yarn comes in size 250 g, how many do I need to buy

    Stacy · February 14, 2018 at 8:26 am

    Hi Linda, Are you buying regular yarn or wool roving yarn? If it’s wool roving, Generally 250 grams is about 10 meters long so you can do the calculations from the above chart, but if you’re talking about 250 g of regular yarn usually wherever your buying it from should say the length. I hope that helped.

Susan Bisho · February 25, 2018 at 11:36 am

Hi Stacey I have four 250 g of hand knitting wool how much more will I need for a bed or large blanket

    Stacy · February 25, 2018 at 10:44 pm

    Is it wool roving or yarn that has been spun? This makes a big difference because usually spun yarn has to be knitted with several strands at a time for the bulk. If you already have 4 x 250g (1 kg) you’ll need about 3 kgs more for a large blanket (if you’re using wool roving), if you’re using super bulky yarn you’ll need to know how many meters in length it is and follow the chart from above. I hope that helped!

I wanted to try arm knitting a blanket, but I’m a beginner. I bought Chunky Boho Loop & Threads Yarn (31 yds, 220g) , its super bulky(6). Do you think I would be able to make a chunky blanket without too many holes? (I’m not even sure if I am making sense, I am really a novice and just wanted to try something new).

    Stacy · March 6, 2018 at 7:50 am

    Hi Mara, You’ll need to buy quite a few more skeins to make a blanket 31 yards won’t be enough, and if it’s super bulky 6 you should knit with 2 or 3 strands at a time so the holes will be smaller. If you have big arms you can lay your work out on the floor and pull the loops through instead of keeping them on your arms, this way you have more control over the size of the stitches and can make the holes smaller.

    I hope that was helpful!
    Happy Arm Knitting,

Stephanie · March 7, 2018 at 10:02 am

Hey there I am a bit confused how many kg or meters I should use. I would like to make a large blanket 70”x80” and I am looking on eBay the description says 250g a ball and 45m chunky wool yarn so how many of those would I need as it seems I need more if I go by the kg than by the metres what do you think. Thanks for your help.

Carlyn Carter · March 24, 2018 at 4:39 pm

Hello! I am glad to have found this page butni also have a question about how. Iarge a blanket i can make with the yarn i have. I have 27 hanks of Bernat Sophia Knit or Knot which, at 7.5 yards/hank comes put to around 200 yards total, measuring length. While the label says its a size 6, with 200 yards i should have enough to make a decent sized blanket according to your chart.

Somehow, it just soesnt add up in my head and wanted to verify my calculations (lol) before I knot and hand knit all this discontinued irreplaceable yarn! ?

Thank you for any help

    Grow Facebook! · March 24, 2018 at 8:15 pm

    Hi Carlyn, YES! You should definitely have enough for a decent sized blanket. And I’d love to see the results when your finished. I’m not farmilar with Bernat Sophia Knit yarn. You’re welcome to share it in my group on facebook called “Arm Knitting and Crocheting.”

    Happy Arm Knitting,

      Carlyn Carter · April 1, 2018 at 5:21 pm

      Heya, Stacy!!

      Phew! Well, as it turned out, i had 22 hanks of 7.5 yards each, so I decided to start with 20 stitches since the yarn was so huge.
      Btw: while the yarn is technically labelled a #6, the core is only complete when woven with the plied of the yarn, and unravels like crazy given the slightest chance. The Bernat Sophia Knit or Knot yarn is actually about the same size as Hobby Lobby’s Eternal Bliss, but the yarn is simply shorter by a half inch, or so.
      Anyway, with what I had, I turned out a fabulously lush, fluffy giant stitch blanket about 48″x 70″ which is a perfect size for snoozing on the couch with mom and dad, or to top my granddaughters new “big girl bed.”
      Turns out, if you keep the stitches CONSISTENT, and even, there is no need to use 2 strands. Also, I found i had to take care to tidy the stitches as i went and not leave any “loopiness” on the backside (uses up yarn, too).
      I solved the knotting issue with super bulky henille yarns, as well – this blanket has ZERO knots to ruin a snuggle, and i even washed and dried the finished blanket several times to test the joins. (The yarn label says cold water hand wash, lay flat to dry, but you KNOW that if it’s a baby’s blankie there isnt gonna be time for all that impractical mess, lol!)
      After all, the blanket is for a 2 year old. ♡
      Next comes about 10 boxes of random Himalaya hanks, for which the yarn is a actually a woven mesh. I would be happy to trade super bulky chenille yarn tips for just ONE good solve on how to connect this crazy discontinued stuff!!! I have enough for 3 blankets (Go, Stacy’s Chart!) So im 1/4 of the way done with xmas with those!!!
      Thanks again, Stacy! I would never have got this project done without your chart!!!


      PS. I have pics, but have no idea how to add them to a message board post like this (since i dont have them stashed online, I guess?)

        Stacy · April 2, 2018 at 7:09 am

        Hi Carlyn,
        What an adventure you’ve had! Don’t worry about the pics. Hard copies are difficult to get online unless you have a scanner or digital camera to take pictures with. If you ever do get them online you can just send them to my facebook page. I’d love to share them with other arm knitters to encourage them using different types of yarn.

        Sounds like your well on your way to finishing Christmas gifts! I’m glad my chart helped. I haven’t any other tips to give since I’ve never used this type of yarn, but it sounds like your managing quite well.

        Happy Arm Knitting,

Celina. Kg make no sence to me. I need oz

Julie · November 12, 2018 at 7:04 pm

I’ve never done anything like this before. I had been looking at the chunky Loops and Threads at Michaels previously but I see that you said I need two strands at a time. If I do that, won’t I need 348y for a large blanket given that I’m using twice as many strands? At $35 a pop, this would put the blanket at over $200 with a discount. They are 54 yds a piece so that means I’d need 7 of them. I’m just trying to determine the right amount so I don’t over/under buy.

    Stacy · November 13, 2018 at 9:06 am

    Hi Julie,
    It sounds like you have the calculations right. Keep in mind that because everyone’s arms are different sizes, you might still need more or less to make the blanket the size you want. But for a general calculation you have it right.

KR · November 15, 2018 at 7:54 pm

Hello, I have purchased the same ‘loops and threads’ yarn (54 yards/ 2.2 lbs) from Micheals. I am attempting to make a baby blanket. That should suffice the amount for a baby blanket yes? But I am trying to figure out how many rows of loops I will need? Thank you!

KR · November 15, 2018 at 7:59 pm

I assume for 30” it would be 10 loops?

    Stacy · November 19, 2018 at 7:02 am

    Hi KR sorry for the late reply, You’ll need to cast on a chain until you have 30″ of chain and then put the loops in the dashes on the back of that chain. 10 loops might be perfect but it all depends on the size of your arm.

CHANDRASEKARAN. Akila · November 19, 2018 at 2:00 am

I am going to make Lego pattern in crochet for a medium blanket, how much woollen yarn is required

    Stacy · November 19, 2018 at 7:04 am

    Generally speaking a crochet blanket uses almost double the amount of yarn a knitted one would, so whatever size you see above on the chart you’ll need to add almost double that.

Julia · December 5, 2018 at 12:59 am

Hi, I bought Loops and Threads bulky yarn from micheals (54 yards to a bundle/ ball). I was just wondering what size blanket I could make from that and how many loops to a row? Or if I should buy another one?

    Stacy · December 5, 2018 at 11:51 am

    Hi Julia 54 yards will be roughly enough to make a 30″ x 30″ baby blanket (it might end up bigger, it just depends on how big or small you make your loops), for a blanket that size I usually cast on about 10, but again it varies greatly with how big or small you make your loops.

Richard Lemro jr · December 19, 2018 at 4:32 am

Hello we are cery new to knitting and hoping to get started with arm knitting. We currently have 162 yards at jumo 7 yarn by loops and threads free spirit.

Can someone give me an approximate size of a blanket this will give me with that yarn length? Im wondering if we need to get another skein of 54 yards at 35 ounces.

All help is greatly appreciated! Thanks somuch

    Stacy · December 21, 2018 at 10:15 pm

    Hi Richard,
    It’s always safer to have more yarn than less so you can make your stitches tighter if you wish. 162 yards will give you roughly a 50″ x 70″ blanket, but this size varies greatly depending on how tight or loose you knit your stitches. Hope that helps! Stacy

Annie · December 27, 2018 at 1:17 am

I am going to arm knit a queen size blanket aprox. 80×90 with Red Heart Irresistible Yarn. Each skein is 29 yards. How many skeins do you think I will need and how many stitches will I need to cast on?

    Stacy · December 27, 2018 at 9:35 am

    Hi Annie, you’ll need roughly 400 yards of yarn, so that would be about 14 skeins if you’re going to make it with a single strand of yarn. If you want it to be a thicker blanket you’ll need to double the yarn as you need with it and in that case you’d need double what I’ve just written. Keep in mind everyone’s stitches are a different size so you might need more or less 400 yards depending on the size of your stitches. I hope that helps!

      Annie · December 29, 2018 at 12:09 am

      Thank you so much Stacy
