How Much Yarn do I Need?

Planning to execute a project but not sure how much yarns to buy? This yarn calculation will help you decide.

The label on the yarns usually says the weight and the length in each ball. But what if you are using some left over yarns or yarn stashes and had no idea of the length of them while your project says you need a certain length to complete?

Well here is the easiest and quickest way to find out. All you need is a tiny amount of yarns cut from the ball you wish to calculate and a digital pocket scale which is available at Amazon.com from under USD10. If you have no access to Amazon, check for it at shops which sells jewelry supplies. This tiny scale usually can measure the weight up to 100grams. The reason why we use the pocket scale is because it is used to measure the weight of jewelries and the accuracy is very close to the actual weight, and secondly we don’t have to cut such a long thread to measure.

Now let check the weight of our stash… It says 19 grams. It means the length of the yarn is
19 x 114.3 cm = 2,171.7 cm = 21.8 M  or 23.75 yards.
Now let’s try with different thickness of yarns. The previous yarn was a Light Worsted yarn. This one now is a thicker yarns, also came without label. All I know is the ball when it was new was 100 grams.

The scale says 1.26 grams…

and it measures 55.2 inches
photo 2 (1)
This ball  is 49.25 grams
Now let’s do the math: 1.26 grams = 55.2 inches
1 gram = 55.2 : 1.26 = 43.8 inches
49.25 grams = 49.25 x 43.8 = 2,157 inches
—> round it off to the nearest 10 inches=2160 inches
2160 : 36 inches (1 yard) = 60 yards.
Easy peasy right?
yarn thickness comparison sm

Above picture shows thickness comparison in different type of yarns. Lily Sugar and Cream is a 4 ply size 4 or Medium Worsted yarn, Indonesian Soft Cotton Big Ply  is a 14 ply yarn, and the Balinese Soft Cotton is an 8 ply yarn.

The number of ply is not  corresponding to the thickness of the yarn. It is simply denote the  number of  threads twisted together to form a yarn. To get a close possible to the pattern requirements you could check your tension or gauge and make adjustment in the size of the hook or substitute the yarn  accordingly. In many cases I double the yarn to achieve the gauge required. Depending on your location on planet earth in some cases it is not easy to get the exact brand. As long as you can get the same content of the yarn you can do the above trick to achieve the nearest result in fabric.

Calculation for Indonesian Yarn

100 gr ball of Katun Bali Halus (Balinese Cotton Yarn) = 169 m

100 gr ball of Katun Besar Soft  (Soft Cotton Big Ply) = 169 m

Calculation Example for Crochet Blanket Using Katun Bali Halus

Baby blanket  = 1500 yard = 1365 m : 169 m = 8 ball

Adult = 3450yard = 3105 m : 169 m = 18.4 ( 19 balls)

Using Katun Besar Soft

Baby blanket = 1300 x 0.91 = 1183 : 169 = 7 balls

Adult  3450 m = 3450 x 0.91 = 3139 : 169 = 18.5 balls (19 balls)

 

This chart estimates how much yarn you will need for specific crafts using yarn produced in Indonesia. For other brands check the label of the yarn.
Indonesia use metric system so don’t forget the conversion 1 Yard = 0.91 m
