# How do I know how much yarn I need for my project?

Finally! The yarns you have carefully selected online or on site have arrived at your home - now you can get started with your latest project. Perhaps you have decided to knit a pretty poncho, a scarf or a headband? But wait a minute - how do I know **how much** **yarn** I'll eventually need?

Otherwise, the amount of yarn you are already using may not be enough to knit or crochet your piece and you will have to start all over again. Of course nobody wants to get into such a mess, because it takes time and, above all, nerves.

There are many reasons to use a different yarn here and there. You want to use a certain color or quality or you have found your personal dream yarn.

In the following article we will show you step by step how to calculate the right amount of yarn for your projects.

Let's first come to the different terms.

## The run length

The yardage describes how long the yarn you bought is. In general, yarns made from finer materials are longer because they have less weight per metre.

Therefore, **rule of thumb** applies: The finer and lighter the yarn, the greater the running length!

## The stitch test

A swatch is a small **sample piece** of a certain size. The instructions that come with your yarn will usually tell you how many stitches and rows it takes to knit a square of a certain size. Since the size can differ depending on the project, it is smarter to do a gauge test beforehand.

## How do I calculate yarn consumption based on yardage?

Well, the formula for this is:

Result: you get the **needed number of wool**

To illustrate the whole thing, here is the following example:

In the instructions for a pullover, the original wool **yarn A** has a **yardage** of ** 100 meters** to **50** **grams**. For the sweater you will need **550** **grams of yarn**.

This results in a total run length of:

**11**(550 divided by 50)

**x 100 meters = 1100 meters**

Now you have the problem, for example, that your **alternative yarn B** is a bit thicker and only **90 meters****50 grams of yarn**.

Proceed as follows: the total run length of **1100 meters** is divided by **90 meters**.

The result is thus **12.2 bobbles**. Instead of 11 you would have to buy 13 bobbles.

With a result like 12.2, it makes more sense to simply buy one more ball to avoid nasty surprises.

**Note**: You can only use the formula if your alternative yarn is knitted or crocheted with the same needle size and the sewing tests match.

Alternatively, you can of course also use online calculator or look at our consumption table and save yourself the calculation

It is also interesting to know that you basically knit **one kilogram of yarn**approximately **half a square meter**.

Now that we've got the theory covered, let's hopefully get to the practice! We hope we were able to help you with our contribution and wish you every success with your latest projects!
