Choosing the right crochet blanket sizes can feel surprisingly confusing — especially when every pattern uses different measurements.
Too small? It won’t be practical. Too big? You’ll run out of yarn halfway through (we’ve all been there!).
This guide will show you exactly what size your crochet blanket should be — whether you’re making a baby blanket, throw, or bed blanket.
If you’d rather follow a pattern that already works, you can start with my Angelece Baby Blanket free pattern or this Granny Square Blanket pattern — both are beginner-friendly and easy to adjust in size.
What Size Should a Crochet Blanket Be?
Standard crochet blanket sizes:
- Baby blanket: 30–36 inches
- Toddler blanket: 36–48 inches
- Throw blanket: 50–60 inches
- Twin bed: 60 x 90 inches
- Queen bed: 90 x 100 inches
Use the chart below for full sizing details.

HOW TO CHOOSE THE RIGHT CROCHET BLANKET SIZE
1. Think About Who It’s For
Baby gift → stick to 30–36 inches
Toddler → slightly longer for growth
Adults → throw or bed size
Baby and throw blankets are the most popular (and quickest to make).
2. Consider the Use (This Matters More Than You Think)
Decorative throw → smaller, lighter
Snuggle blanket → bigger and drapey
Pram blanket → compact and practical
A common mistake is making a blanket that looks nice but isn’t usable.
3. Match Your Yarn + Time Commitment
Chunky yarn = faster = bigger blankets
DK / cotton = slower = better for baby sizes
If you’re short on time → go for baby or lap size.
HOW TO RESIZE ANY CROCHET BLANKET
Option 1: Adjust Starting Chain
Most blanket patterns (like my Angelece blanket) use a repeat.
Example:
Multiple of 12 + 1
Add repeats → make it wider
Reduce repeats → make it smaller
For best results: Make your blanket approx. 4cm (1.5 inches) shorter in both width and length if you plan on adding a border.
Option 2: Add More Rows
More rows = longer blanket
Fewer rows = shorter blanket
Simple but effective.
Option 3: Use a Border to Adjust Size
Adds 1–3 inches easily
Makes blankets look more polished
Fixes slightly “off” sizing

COMMON CROCHET BLANKET SIZE MISTAKES
❌ Guessing the size
Always check a chart (like above)
❌ Not checking gauge
Even a small difference adds inches across a blanket
❌ Making it “just a bit bigger”
This turns into:
→ More yarn
→ More time
→ More frustration
