How Much Yarn Do You Need For A Baby Blanket?

Welcoming a new baby into the world is such an exciting time. As you prepare the nursery and shop for tiny clothes, you’ll also want to start thinking about handmaking a special baby blanket as a keepsake gift for the new arrival.

If you’re short on time, here’s a quick answer to your question: For a medium-sized baby blanket made with worsted weight yarn, you’ll need around 800-1200 yards of yarn. The exact amount depends on the size of the blanket and thickness of the yarn.

In this comprehensive guide, we’ll cover everything you need to know about how to calculate the yardage for your dream baby blanket. You’ll learn about different yarn weights, typical baby blanket sizes, and how to estimate yardage based on your selected pattern and stitches.

How Big Should a Baby Blanket Be?

When it comes to knitting or crocheting a baby blanket, one of the first questions that comes to mind is: How big should it be? Baby blankets come in various sizes, depending on their purpose and how they will be used. Here are some common sizes for different types of baby blankets:

Crib/Stroller Blanket Size

A crib or stroller blanket is typically larger than other types of baby blankets. It should be large enough to cover the entire crib mattress or fit comfortably over a stroller. The average size for a crib or stroller blanket is around 30 inches by 40 inches.

This size allows for ample coverage and room for the baby to grow.

Carriage/Pram Blanket Size

A carriage or pram blanket is designed to keep the baby warm and cozy while out for a walk in a carriage or pram. These blankets are usually smaller than crib blankets, measuring around 24 inches by 30 inches.

This size is perfect for wrapping the baby snugly without overwhelming them with excess fabric.

Swaddle Blanket Size

Swaddle blankets are used to tightly wrap newborns, providing them with a sense of security and warmth. These blankets are typically square-shaped and measure around 40 inches by 40 inches. The generous size allows for easy swaddling and creates a snug environment for the baby.

Car Seat Blanket Size

A car seat blanket is designed to fit over a baby’s car seat or infant carrier. These blankets are often slightly smaller than crib blankets to ensure a secure fit and prevent any interference with the car seat’s safety features.

The average size for a car seat blanket is around 22 inches by 30 inches.

Stuffed Animal Blanket Size

Stuffed animal blankets, also known as loveys, are small blankets that are attached to stuffed animals. These blankets provide comfort and familiarity to babies and toddlers when they sleep or play. The size of a stuffed animal blanket can vary, but they are typically around 12 inches by 12 inches, making them easy for little ones to hold and carry around.

Remember, these sizes are just guidelines, and you can always adjust them to suit your preferences or the specific needs of the baby. It’s important to keep in mind that babies grow quickly, so it may be beneficial to make the blanket slightly larger to accommodate their growth.

Additionally, different yarn weights and stitch patterns can also affect the final size of the blanket.

For more information on baby blanket sizes and knitting or crocheting patterns, you can visit websites such as AllFreeCrochet or Ravelry. These websites offer a wide range of resources and patterns for all skill levels.

Choosing a Yarn Weight

When it comes to choosing the right yarn for your baby blanket, one of the first decisions you’ll need to make is selecting the appropriate yarn weight. Yarn weight is determined by the thickness and heaviness of the yarn, and it plays a crucial role in determining the final look and feel of your project.

Bulky and Super Bulky Yarns

If you’re looking to create a cozy and warm baby blanket, bulky and super bulky yarns are excellent options. These yarns are thick and heavy, resulting in a blanket that is soft, plush, and perfect for colder climates.

However, keep in mind that due to their thickness, these yarns may take up more space and can result in a heavier blanket.

Worsted Weight Yarns

Worsted weight yarns are a popular choice for baby blankets due to their versatility. They are neither too thick nor too thin, making them suitable for a wide range of blanket designs. Worsted weight yarns are easy to work with and provide a good balance between warmth and breathability.

They are also readily available in a wide variety of colors and fibers, allowing you to create a blanket that matches your style and preferences.

Sport and DK Weight Yarns

Sport and DK weight yarns are lighter and thinner than worsted weight yarns, making them perfect for creating lightweight and breathable baby blankets. These yarns are often used for delicate and intricate designs, such as lace patterns or detailed stitch work.

While they may not provide as much warmth as bulkier yarns, they are ideal for use in moderate climates or during the warmer months.

Laceweight and Fingering Yarns

Laceweight and fingering yarns are the lightest and thinnest yarn weights available. They create delicate and airy baby blankets that are perfect for warmer climates or as lightweight coverings during the summer.

Blankets made with laceweight and fingering yarns have a delicate drape and can showcase intricate stitch patterns beautifully. These yarns require more time and patience to work with due to their thinness, but the end result is often worth the effort.

Remember, the yarn weight you choose will not only impact the look and feel of your baby blanket but also the amount of yarn you’ll need to complete your project. It’s always a good idea to consult the yarn label or a trusted yarn calculator to determine the approximate amount of yarn required for your specific pattern and desired dimensions.

Estimating Yardage for Common Blanket Sizes and Yarn Weights

Worsted Weight Blankets

When it comes to making a baby blanket using worsted weight yarn, it’s important to consider the size of the blanket you want to create. A typical baby blanket measures around 30×40 inches, but you can adjust the size based on your preference.

On average, you will need approximately 1,200 to 1,500 yards of worsted weight yarn to complete a baby blanket of this size.

However, keep in mind that this is just an estimate and the actual yardage can vary depending on your stitch pattern, tension, and the desired drape of the blanket. It’s always a good idea to buy a little extra yarn to ensure you have enough to complete your project.

DK Weight Blankets

If you prefer to use DK weight yarn for your baby blanket, the yardage required will be slightly different. DK weight yarn is lighter than worsted weight, so you will need more yardage to achieve the same size blanket.

For a 30×40 inch baby blanket using DK weight yarn, you will need approximately 1,800 to 2,200 yards.

Again, this is just an estimate and the actual yardage can vary depending on factors such as stitch pattern, tension, and desired drape. It’s always a good idea to check the yarn label for recommended yardage and adjust accordingly.

Bulky Weight Blankets

If you want to create a baby blanket using bulky weight yarn, you will need even less yardage compared to worsted or DK weight yarns. Bulky weight yarns are thicker and work up quickly, so you can make a cozy blanket in no time.

For a 30×40 inch baby blanket using bulky weight yarn, you will need approximately 800 to 1,000 yards.

As with the other yarn weights, it’s important to consider factors such as stitch pattern, tension, and desired drape when estimating yardage. Additionally, always check the yarn label for recommended yardage and adjust accordingly.

Remember, these yardage estimates are just a starting point and can vary based on individual factors. It’s always best to have a little extra yarn on hand to ensure you have enough to complete your baby blanket. Happy knitting or crocheting!

Tips for Accurately Calculating Yardage

Factor in Repeat Rows and Stitches

When calculating the amount of yarn needed for a baby blanket, it’s important to consider the pattern’s repeat rows and stitches. Some patterns may have a repeating pattern that requires more yarn than a simple, straightforward design.

Take note of the number of rows and stitches that are repeated and factor that into your calculations. This will ensure that you have enough yarn to complete the entire project without running out.

Account for Bind Off and Fringe

Don’t forget to account for the yarn needed for the bind off and any fringe you may want to add to the baby blanket. The bind off requires a small amount of yarn to secure the stitches and finish the edge of the blanket.

Additionally, if you plan on adding fringe, make sure to include the yardage needed for that as well. It’s better to have a little extra yarn than to run out right at the end.

Get Sample Measurements

If you’re using a pattern for your baby blanket, check if the pattern provides sample measurements. These measurements can give you a good idea of the average size of the blanket and help you estimate the amount of yarn needed.

If the pattern doesn’t provide measurements, you can measure a similar-sized blanket to get an estimate. Remember, it’s always better to err on the side of caution and purchase a little extra yarn to be safe.

Purchase Extra Yarn

It’s always a good idea to purchase a little extra yarn when calculating yardage for a baby blanket. This extra yarn will come in handy if you make any mistakes or need to make adjustments to the pattern.

Plus, if you have leftovers, you can use them for other small projects or to make matching accessories for the blanket, such as booties or a hat. Having extra yarn ensures that you have enough to complete the project and allows for more flexibility in your knitting or crocheting process.

Yarn Care Tips for Baby Blankets

Choose a Superwash Yarn

When selecting yarn for a baby blanket, it is important to consider the care and durability of the yarn. One excellent option is to choose a superwash yarn. Superwash yarns are specially treated to make them machine washable, which is a great convenience for busy parents.

These yarns are designed to withstand repeated washing without shrinking or losing their softness. With a superwash yarn, parents can easily clean their baby’s blanket without any worries.

Go with a Sturdy Natural Fiber

Another important factor to consider when choosing yarn for a baby blanket is the fiber content. Opting for a sturdy natural fiber, such as cotton or bamboo, can be a great choice. These fibers are soft, breathable, and hypoallergenic, making them perfect for a baby’s delicate skin.

Additionally, they are durable and can withstand frequent washing without losing their shape or softness. Choosing a natural fiber yarn ensures that the baby blanket will be both comfortable and long-lasting.

Wash Blanket Before Gifting

Prior to gifting a baby blanket, it is essential to wash it thoroughly. This step helps to remove any dirt, allergens, or chemicals that may be present on the yarn or fabric. Washing the blanket also ensures that it is fresh and clean for the baby’s use.

It is recommended to follow the care instructions provided by the yarn manufacturer to maintain the integrity of the blanket while washing it. By washing the blanket before gifting, you can give the parents peace of mind knowing that their baby will be wrapped in a clean and safe blanket.

Recommend Gentle Care Instructions

When giving a baby blanket as a gift, it is helpful to provide the parents with gentle care instructions. This can include recommendations to wash the blanket on a delicate or gentle cycle, using mild detergent.

It is also advisable to suggest air drying or using a low heat setting in the dryer to prevent any damage to the yarn. By offering these care instructions, you can ensure that the blanket remains in excellent condition for the baby to enjoy for years to come.


Handmaking a blanket is one of the most thoughtful baby gifts you can give. With this yardage guide, you’ll have the knowledge you need to determine how much yarn is required for any baby blanket pattern and size. Just be sure to purchase a little extra yarn to be safe. Happy knitting or crocheting!

The arrival of a newborn is such a cherished occasion. May your lovingly crafted blanket become a treasured heirloom that the parents will pass down to baby someday. Sweet dreams and congratulations to the whole family!
