How Many Yards Of Yarn Are In 100 Grams? The Complete Guide

If you’re short on time, here’s a quick answer to your question: 100 grams of yarn is equivalent to approximately 218 yards. However, the exact yardage can vary slightly depending on the thickness, fiber type, and ply of the yarn.

For crafters and knitters, knowing how to convert grams of yarn into yards is an essential skill for ensuring you purchase the right amount of yarn for your projects. In this comprehensive guide, we’ll explain everything you need to know about the relationship between yarn weight and yardage so you can expertly calculate how many yards are in 100 grams, no matter what type of yarn you are working with.

What Factors Impact the Yardage of Yarn

When it comes to determining the yardage of yarn, there are several factors that can influence the amount of yarn you get in a specific weight. Understanding these factors is essential for any knitter or crocheter who wants to plan their projects accurately and avoid running out of yarn.

Yarn Weight

One of the primary factors that impact the yardage of yarn is its weight. Yarn weight refers to the thickness of the yarn, which can vary from very fine to super bulky. Generally, the thinner the yarn, the more yardage you’ll get from a specific weight.

For example, a 100-gram skein of fingering weight yarn may contain several hundred yards, while the same weight of bulky yarn may only have a fraction of that yardage.

It’s important to note that yarn weight is not standardized across all brands and manufacturers. However, most yarn labels provide information about the weight category, which can help you estimate the yardage.

You can also check the Craft Yarn Council’s website for a detailed breakdown of yarn weights and their corresponding yardage ranges.

Yarn Fiber

The type of fiber used in the yarn can also impact the yardage. Different fibers have different densities and structures, which can affect how much yarn is needed to achieve a specific weight. For example, yarn made from natural fibers like cotton or silk may weigh more than synthetic yarns like acrylic or nylon.

As a result, you may get fewer yards of yarn in a specific weight if you’re using a denser fiber.

Additionally, the texture of the yarn can also influence the yardage. Yarns with a looser twist or a more airy structure may take up more space and therefore have less yardage compared to tightly spun yarns.

Keep these factors in mind when selecting yarn for your projects, especially if you’re working with a specific yardage requirement.


The number of plies in the yarn can also impact the yardage. Ply refers to the number of individual strands that are twisted together to form the yarn. Yarn can be single-ply, meaning it consists of a single strand, or multi-ply, meaning it has multiple strands twisted together.

In general, single-ply yarns tend to have more yardage than multi-ply yarns of the same weight. This is because the individual strands in multi-ply yarns take up more space, resulting in less total yardage.

However, it’s important to note that the ply is not the only factor that determines yardage, and there can be variations within each ply category.

To accurately determine the yardage of a specific yarn, it’s best to refer to the label or contact the manufacturer for the most accurate information. Remember, these factors can vary from yarn to yarn, so it’s always a good idea to check the specific details for the yarn you’re using.

Average Yardage for Common Yarn Weights

Lace Weight Yarn

Lace weight yarn is the thinnest yarn weight category available. It is often used to create delicate shawls, doilies, and intricate lace patterns. On average, lace weight yarn contains around 400-600 yards per 100 grams.

However, it’s important to note that yardage can vary between different brands and fibers. If you’re unsure about the yardage of a specific lace weight yarn, be sure to check the label or the manufacturer’s website for more information.

Super Fine / Sock Weight Yarn

Super fine or sock weight yarn is slightly thicker than lace weight yarn but is still considered very lightweight. This type of yarn is commonly used for making socks, as well as lightweight garments and accessories.

On average, super fine or sock weight yarn contains approximately 350-450 yards per 100 grams. Again, it’s always a good idea to double-check the label or manufacturer’s website for accurate yardage information.

Fine / Baby Weight Yarn

Fine or baby weight yarn is a popular choice for baby clothes, blankets, and delicate garments. It is slightly thicker than super fine yarn but still falls into the lightweight category. On average, fine weight yarn contains around 250-350 yards per 100 grams.

Remember to verify the yardage specifics for the particular brand and fiber you are using.

Light / DK Weight Yarn

DK weight yarn, also known as light weight yarn, is a versatile option that can be used for a wide range of projects. It is a bit thicker than fine weight yarn and is often chosen for sweaters, hats, and scarves. On average, DK weight yarn contains approximately 200-250 yards per 100 grams.

As always, be sure to check the label or manufacturer’s website for accurate yardage information.

Medium / Worsted Weight Yarn

Worsted weight yarn is one of the most commonly used yarn weights. It is a great all-purpose yarn that is suitable for a wide variety of projects, from garments to home decor. On average, worsted weight yarn contains around 150-200 yards per 100 grams.

This yardage can vary slightly depending on the brand and fiber content of the yarn.

Bulky Weight Yarn

Bulky weight yarn is a thicker option that is often chosen for warm and cozy projects like blankets, scarves, and hats. It works up quickly due to its larger size. On average, bulky weight yarn contains approximately 100-150 yards per 100 grams.

However, it’s always a good idea to check the label or manufacturer’s website for accurate yardage information before starting your project.

Super Bulky Weight Yarn

Super bulky weight yarn is the thickest yarn category available. It is perfect for creating chunky and warm projects like blankets, cowls, and oversized sweaters. On average, super bulky weight yarn contains around 50-100 yards per 100 grams.

This yarn weight is known for its quick results and instant gratification. As with other yarn weights, double-check the label or manufacturer’s website for accurate yardage information.

How to Calculate Yards from Grams

When working with yarn, it’s important to know how many yards are in a given weight of yarn. This information is useful for planning projects and estimating the amount of yarn needed. Here are three methods to calculate the number of yards from grams:

1. Use Yarn Weight Recommendations

One of the easiest ways to determine the yardage of a specific weight of yarn is to consult the yarn weight recommendations. Yarn manufacturers often provide guidelines that indicate the average yardage for a specific weight of yarn.

For example, a typical recommendation for worsted weight yarn is around 200 yards per 100 grams. By following these recommendations, you can quickly estimate the yardage based on the weight of the yarn you have.

2. Weigh a Yarn Sample

If you don’t have access to yarn weight recommendations or want to double-check the yardage, you can weigh a yarn sample and calculate the yardage yourself. Start by weighing a small amount of yarn, such as 10 grams, using a digital kitchen scale.

Next, measure the length of the sample in yards using a tape measure. Divide the length by the weight to get the approximate yardage per gram. Multiply this number by the total weight of your yarn to find the total yardage.

3. Check the Ball Band

Another valuable source of information is the ball band that comes with the yarn. The ball band usually includes important details about the yarn, such as the weight, yardage, and fiber content. Look for the yardage per weight listed on the ball band.

This information is typically presented as the yardage per 100 grams, so you can calculate the yardage for your specific weight by dividing the listed yardage by 100 and then multiplying it by the weight of your yarn.

Remember, these methods provide approximate yardage calculations. The actual yardage may vary slightly due to variations in yarn thickness and density. It’s always a good idea to have a little extra yarn on hand, just in case.

Tips for Buying the Right Amount of Yarn

Factor in Loss from Swatches and Mistakes

When purchasing yarn for a project, it’s essential to consider the potential loss from swatches and mistakes. Knitters and crocheters often create small swatches to test their gauge before starting a project.

These swatches require some yarn, which should be taken into account when estimating the amount needed. Additionally, mistakes happen, and unraveling and reworking sections of a project can result in the loss of yarn. It’s a good idea to buy a little extra to account for these potential losses.

Purchase Extra for Large Projects

For larger projects such as blankets, sweaters, or shawls, it’s advisable to purchase extra yarn. Calculating the exact amount needed for these projects can be challenging, and running out of yarn midway can be frustrating.

It’s better to have a surplus than to risk not having enough to complete the project. The amount of extra yarn may vary depending on the complexity and size of the project. It’s always better to err on the side of caution and buy a little more than you think you’ll need.

Buy All Yarn at Once

If you’re working on a multi-colored or multi-skein project, it’s crucial to buy all the yarn you need at once. Yarn dye lots can vary, even within the same colorway, and buying yarn at different times may result in variations in color or texture.

To ensure consistency throughout your project, it’s best to purchase all the yarn you need in one go. This way, you can be confident that all the skeins will match perfectly.

Remember, it’s always better to have a little extra yarn than not enough. Having some leftover yarn can be useful for making small accessories or repairing any future damage to your project. By following these tips, you can ensure that you have the right amount of yarn for your next knitting or crochet project.


Now that you understand the relationship between yarn weight, fiber, ply, and yardage, you can confidently purchase the right amount of yarn for your next knitting or crochet project. With some simple calculations, you’ll know exactly how many yards are in 100 grams of yarn.

The specifics may vary slightly between brands, but you now have the knowledge to make informed estimates. Knowing how to convert grams to yards ensures you’ll end up with the perfect amount of yarn for any pattern.
