Many yarns come in balls and skeins that weigh 100 grams or about 3.5 ounces of yarn. You may be wondering how much yarn is in 100 grams for your particular yarn.
How many yards are in 100 grams of yarn will vary depending on the type of yarn. The weight of yarn, the thickness of the yarn, and the fiber content affect the yarn yardage.
The biggest factor is the weight of your yarn in the standard yarn weight system published by the Craft Yarn Council. 100 grams of a bulky yarn will contain less yardage than 100 grams of a finer yarn like a lace weight yarn.
There are several ways to figure out how many yards are in 100 grams of yarn:
- Use a table to help you estimate
- Find the information using the yarn label
- Look the information up on Ravelry
- Look the information up on YarnSub
- Find the information on the yarn company’s website or another website
How can I use this information?
Before we get into the details of the five different methods, you may be wondering how you can use this information.
Knowing how many yards are in 100 grams of yarn will help you out if you want to know if you have enough yarn for a project.
For example, you may have a partial skein of leftover yarn and you want to see if you have enough yarn for a pattern. No one wants to play yarn chicken and risk running out.
For example, you may have a crochet pattern or a knitting pattern that calls for 120 yards of yarn for a small project. Using one of the five methods below, you determine that there are 218 yards in 100 grams of your yarn.
So how many yards are in your partial skein? Here are the steps you would follow to figure it out:
- Weigh your partial skein in grams. You can use a digital kitchen scale for this purpose.
- Divide the weight of your partial skein by 100 grams.
- Take the result of Step 2 and multiply it by the number of yards in 100 grams. This will give you how many yards are in your partial skein.
And here are the steps for our example:
- Weigh your partial skein. Let’s say it comes out to 57 grams.
- Divide the weight of your partial skein by 100 grams. So we would divide 57 grams by 100 grams and get .57.
- Then we take the result of Step 2 and multiply it by the number of yards in 100 grams. So for the example, we would multiple .57 times 218 yards. The result would be approximately 124 yards.
Since our pattern calls for 120 yards, we will probably be okay. If you’d like a little more leeway than 4 extra yards, you could also look for another yarn.
Use This Table to Determine Approximately How Many Yards Are in 100 Grams of Yarn
Below is a handy table that gives you the approximate number of yards contained in 100 grams of yarn by its weight category.
Please note that this table gives estimates only and should only be used as a rough calculation of yardage. Often a particular yarn will be a little above or below the range shown on the table.
Still the table can give you a general rule of thumb to get you an approximate estimate or generic amount of yardage per 100 grams.
And if you are missing information about your yarn like it’s name or the ball band, the table can be a way to get you an approximate yardage per 100 grams.
Often a pattern will use a common name for a particular yarn weight. For example, a Super Fine Weight Yarn (#1) might be called Sock, Fingering, or Baby yarn.
Here’s the table with other common names for the yarn weights in case your pattern is using one of the other common names for the yarn weight.
|Yarn Weight||Other Name(s)||Approximate Yards per 100 grams|
|Lace #0||Light Fingering||850 – 950|
|Super Fine #1||Sock, Fingering, Baby||440 – 460|
|Fine #2||Sport, Baby||330 – 440|
|Light #3||DK yarn, Light Worsted||250 – 350|
|Medium #4||Worsted, Aran||170 – 220|
|Bulky #5||Chunky, Craft, Rug||110 – 140|
|Super Bulky #6||Super Bulky, Roving||60 – 110|
|Jumbo #7||Jumbo, Roving||10 – 30|
Find Out How Many Yards Are in 100 Grams Using the Yarn Label
You can use the yarn label to determine how many yards are in 100 grams for a particular ball of yarn. This is the most accurate method. It works especially well if you still have the yarn label and if the label lists the grams.
You may also hear the yarn label being called the ball band. These mean the same thing.
100g Yarn Skeins
The easiest situation is when you have the yarn label, and the ball or skein of yarn weighs 100 grams. Then, it’s just a simple matter of looking up how many yards or yarn are in one ball or skein.
For example, in the following photos, each of the yarns comes in 100g yarn skeins. So, you can easily see how many yards of yarn are in 100 grams.
Both of the yarns below are worsted weight. The have different fiber contents however. One of them is 100% cotton and the other is an acrylic blend. Their yardages differ slightly.
The Dishie yarn below has 190 yards in 100 grams of yarn.
The Brava Tweed yarn below has 218 yards in 100 grams of yarn.
50g Yarn Skeins
The second easiest situation is when you have the yarn label, and the yarn comes in 50g skeins. Then, it’s simply a matter of looking up how many yards are in one ball or skein and multiplying it by 2.
For example, the yarn in the photo below comes in balls that weigh 50 grams. Each ball contains 88 yards. So, then you multiple the 88 yards by 2, and you get 176 yards in 100 grams.
Yarn Skeins of Varying Weights
Finally, you can use a simple equation if your yarn comes in some other number of grams. You just need to do a little math.
For Step One of the Equation, divide 100 grams by the number of grams in your ball of yarn.
For Step Two of the Equation, multiply you answer from step one by the number of yards that are in your ball of yarn.
The resulting number will be the number of yards in 100 grams.
Here’s the equation written out.
And here are some examples for different balls of yarn.
In the photo below we have 227 grams and 129 yards.
So, step one, we divide 100 grams by 227 grams, and we get approximately 0.44.
Step two, we then multiply 0.44 times the 129 yards in the ball of yarn.
The result is approximately 57 yards in 100 grams of yarn.
This is a thick yarn so it makes sense that there are fewer yards in 100 grams.
Note this is a Super Bulky #6 yarn, and 57 yards puts us just a little below the range in the table. This illustrates how the table gives us estimates. The other methods like using the ball band are more accurate.
In the photo below we have 140 grams and 362 yards.
So, step one, we divide 100 grams by 140 grams, and we get approximately 0.71.
Step two, we then multiply 0.71 times the 362 yards in the ball of yarn.
The result is approximately 257 yards in 100 grams of yarn
In the photo below we have 85 grams and 197 yards.
So, step one, we divide 100 grams by 85 grams, and we get approximately 1.18.
Step two, we then multiply 1.18 times the 197 yards in the ball of yarn.
The result is approximately 232 yards in 100 grams of yarn.
Note this is a Worsted Weight #4 yarn, and 232 yards puts us just a little higher than the range in the table. This further illustrates how the table gives us estimates. The other methods like using the ball band are more accurate.
