Crochet a baby blanket as a gift or for your little one with this simple pattern. One of the first things a beginner, or even a long-time crocheter, can get hung up on when creating a crochet baby blanket is How much yarn you need to crochet a baby blanket.
Knowing this will help keep you from getting too little yarn (and prevent you from getting too much). In this guide, we’ll cover everything you need to know, from blanket sizes to yarn weight and stitch patterns. Let’s get started!

Understanding How much yarn for a crochet blanket
Before you begin your crochet project, you must understand the different factors that will influence how much yarn you’ll need. These include the blanket size, the weight of the yarn, and the type of stitch you plan to use.
Common Baby Blanket Sizes
Baby blankets can vary greatly in size depending on their intended use. Here are some common sizes:
- Lovey: A small, comforting blanket, typically around 12″ x 12″. It’s perfect for newborns or as a security blanket.
- Receiving Blanket: Usually around 30″ x 36″. This size is perfect for swaddling a baby.
- Crib Blanket: This blanket usually measures 36″ x 52″. It’s large enough to cover a crib and is great for toddlers.
- Toddler Blanket: About 40″ x 60″. This is often used once a child has outgrown their crib.
Yarn Weight and Yardage
The weight of the yarn you select will be a significant factor in this amount. Lighter yarn weights (sport, sock) require more yardage to cover the same area than heavier-weight yarn (bulky, worsted). Here are some standard yarn weights and how much (in yards) you’ll want to use for a typical baby blanket size:
- Fingering/Sport Weight: Around 1,200–1,500 yards for a standard baby blanket (30” x 36”).
- DK/Light Worsted: Around 1,000–1,125 yards.
- Worsted Weight: Around 800–1,000 yards.
- Bulky Weight: Around 600–800 yards.
It’s always a good idea to verify the yardage on your yarn packaging for specific yardage recommendations, but these should give you a general idea.
Stitch patterns and yarn used
The stitch pattern you choose will also influence how much yarn you will need. Tight stitches such as single crochet or half double crochet also use up more yarn, simply because you are packing the space more tightly, but they can also make the piece more dense and, therefore, warmer by keeping out the wind. By contrast, more open patterns such as shells or lace use less yarn. For example:
- Tight Stitches (such as single/treble crochet): You should only need the recommended hook size as specified for your yarn but you may need the next size up, with very tight/grippy tension tight hooks work best and require more yarn, often more than the specified amount for a weight.
- Lacy or Open Patterns (for example, fan stitch, shell stitch): Lacy Crochet uses less yarn since the stitches are more spaced out.
Knowing your pattern will help you plan more accurately.
What Are the Sizes of Crochet Baby Blankets?
Baby blankets come in a variety of sizes depending on their purpose. Here are some of the most common:
- Lovey Blanket (10” x 10”): A small security blanket for babies to snuggle with.
- Stroller Blanket (30” x 36”): Perfect for covering a baby in a stroller while keeping it portable.
- Receiving Blanket (40” x 40”): Slightly larger, often used for swaddling or laying on the floor.
- Crib Blanket (45” x 60”): A larger blanket made to keep the baby warm in the crib.
How Much Yarn Do You Need for a Baby Blanket?

Once you understand the key factors (size, yarn weight, and stitch), it’s time to estimate how much yarn you’ll need. Here’s a simple chart that outlines typical yarn requirements based on common baby blanket sizes:
Blanket Type | Size | Yarn Needed (Worsted Weight) |
Lovey Blanket | 10” x 10” | Around 200 yards |
Stroller Blanket | 30” x 36” | 750–1,000 yards |
Receiving Blanket | 40” x 40” | 1,200–1,500 yards |
Crib Blanket | 45” x 60” | 1,500–2,000 yards |
If you use a lighter yarn, make sure you buy extra to account for the increased yardage.
Selecting the Right Yarn
Selecting the perfect yarn for a baby blanket is essential; you will want something that is soft and sturdy but also that is low maintenance. Here are the most popular yarns:
Recommended Yarn Types
Acrylic Yarn: It is one of the most popular baby blanket yarns. It’s soft, inexpensive, machine washable — in other words, all but required for babies.
Cotton Yarn: Cotton is a breathable yarn that is soft on baby skin but still not as soft as acrylic. It’s good if you live somewhere hot.
Bamboo Blends: This is a natural fabric which is hypoallergenic and green friendly. Blends are a great option that often yield a soft, smooth fabric, which is ideal for a baby’s sensitive skin.
Yarn Weight Guide
Here’s a quick reference guide to help you choose the right yarn weight for your project:
Weight | Category | Recommended Use |
1 | Fingering | Delicate items like shawls |
2 | Sport | Lightweight garments |
3 | DK | Baby blankets, lightweight throws |
4 | Worsted | Afghans, throws, and blankets |
5 | Bulky | Quick projects, winter blankets |
If you’re unsure about which weight to use, DK (double knit) or Worsted weight yarn is often the most versatile and popular for baby blankets.
How to Make Your Yarn Go Further
Your skeins will need stretching to use the yardage to its fullest. Here are some valuable tips on how to make your yarn last longer during the whole project:
- Choose simpler stitches: A plain double crochet stitch takes up less yarn than complex textures or patterns.
- Strategically plan your pattern: Seek out patterns that maximize coverage without requiring more yardage —this typically means they’re either mesh or lace designs.
- Be consistent with tension: Maintaining a constant crochet tension from start to finish will help prevent wasted yarn on misshapen stitches.
Saving Money on Crochet Yarn
Yarn costs can certainly add up, especially if you are working on something larger. Here are some strategies for keeping costs down:
- Buy in Bulk: Lots of craft stores and online stores offer a discount when you buy several skeins or full bundles of yarn.
- Keep an Eye Out for Sales: Pay attention to end-of-season or seasonal sales to build up your stash of fancy yarns for less.
- Another use Yarn: Use yarn from previous projects, or even yarn from a thrift store find, it in your cropped baby blanket.
Avoid Running Out of Yarn (or Having Too Much)
Either having a bunch of yarn leftover or running out when you’re halfway through a project is no fun. To avoid this:
- Always look over the pattern requirements: If you’re working off a certain pattern, it will typically inform you of how much yarn to work with. It does not hurt to order 10-15% more as a precaution.
- Use a yarn calculator: If you’re creating a project with no pattern, use an online yarn calculator, which can estimate yardage based on project size, stitch type, and yarn weight.
