Best Blanket Size for a Pram, Moses Basket or Cot? A Simple UK Guide
If you’ve ever stood staring at baby blankets wondering why some look tiny and others could practically cover a sofa… you’re not alone.
One of the most confusing things about shopping for baby blankets is that there isn’t one “standard” size that works for everything.
A blanket that’s perfect for a pram might feel bulky in a Moses basket. And a blanket that works beautifully for a newborn may suddenly seem far too small once your baby turns into a blanket-stealing toddler.
In this guide we’ll break down the best blanket sizes for:
- prams
- Moses baskets
- cots
- toddler beds
- everyday travel
So you can choose a blanket that’s actually practical for real life — not just one that looks cute folded in a nursery basket.

Why Blanket Size Actually Matters
When it comes to baby blankets, size makes a surprisingly big difference.
The right blanket should feel:
- cosy without being bulky
- easy to tuck around baby
- lightweight enough for layering
- practical for everyday use
A blanket that’s too large can bunch up awkwardly in smaller spaces like prams and Moses baskets, while one that’s too small may not provide enough coverage as your child grows.
That’s why many parents end up using different blanket sizes for different stages and situations.
What Size Blanket Is Best for a Pram?
For prams and pushchairs, smaller blankets are usually the most practical option.
A baby blanket around 55 × 70 cm works beautifully because it can:
- tuck neatly around baby
- stay secure while moving
- avoid dragging over the sides
- fold easily into changing bags and buggy baskets
This size is ideal for:
- pram walks
- car journeys
- naps on the go
- everyday outings
Many parents find their smaller pram blanket quickly becomes the “take everywhere” blanket because it’s lightweight, portable and easy to manage.
At SnugaBug, our hand-knitted chenille baby blankets are designed in approximately 55 × 70 cm, making them ideal for prams, newborn snuggles and everyday use.
What Size Blanket Is Best for a Moses Basket?
Moses baskets usually work best with compact, lightweight blankets rather than oversized ones.
Blankets around 50–70 cm wide are often ideal because they provide warmth without too much excess fabric.
A smaller blanket helps:
- keep baby comfortable
- make layering easier
- avoid bunching inside the basket
- fit neatly around smaller sleeping spaces
Because newborns spend so much time sleeping in Moses baskets during the early months, many parents prefer having a dedicated smaller blanket specifically for bedside naps and overnight use.
Soft chenille blankets are especially popular for Moses baskets because they feel cosy and comforting while still being lightweight enough for everyday layering.
What Size Blanket Is Best for a Cot?
As babies grow and move into cots or cot beds, slightly larger blankets often become more practical.
Blankets around 70 × 90 cm work well for:
- older babies
- toddlers
- nap times
- cot beds
- sofa cuddles
The extra size gives growing children more coverage while still feeling manageable and lightweight. You can browse my collection of chenille toddler sized blankets here
Larger blankets can also last much longer through toddlerhood, which is why many parents transition to toddler-sized blankets once their baby outgrows the newborn stage.

When Should You Move From a Cot Blanket to a Toddler Blanket?
What Size Blanket Is Best for a Toddler Bed?
Toddlers often prefer blankets that feel soft, familiar and easy to carry around themselves.
A toddler blanket around 70 × 90 cm is usually a great in-between size because it works for:
- toddler beds
- naps
- buggy rides
- travel
- quiet time on the sofa
Many toddlers also become emotionally attached to their favourite blanket, especially if it’s part of their bedtime routine.
That’s why softness and texture become just as important as size during this stage.
Chenille toddler blankets are particularly popular because they’re:
- ultra-soft
- comforting to touch
- cosy without feeling heavy
- easy to fold and carry
And realistically? Once a toddler decides a blanket is their blanket, it’s probably coming everywhere with you.
Do Babies Need Different Blankets for Home and Travel?
Many parents eventually discover that having one blanket for everything isn’t always practical.
A smaller blanket is often easier for:
- prams
- car seats
- nappy bags
- travel
- nursery drop-offs
While slightly larger blankets may work better for:
- cots
- toddler beds
- sofa snuggles
- nap time at home
This is one reason many families end up with:
- a favourite pram blanket
- a bedtime blanket
- a comforter for soothing and cuddles
And honestly, once one inevitably ends up covered in snacks or mysteriously missing under the sofa, having a backup suddenly feels like a very sensible life decision.
What About Baby Comforters?
Comforters are much smaller than blankets and are designed primarily for emotional comfort rather than warmth.
You may also hear them called:
- loveys
- snuggle squares
- security blankets
Typical comforter sizes include:
- 30 × 30 cm standard comforters
- 40 × 40 cm large comforters
Because comforters are lightweight and easy for little hands to hold, many babies become strongly attached to them as part of their sleep routine.
They’re often the item that travels absolutely everywhere — usually with slightly dramatic consequences if accidentally left behind. Have a little look at our handmade baby comforters.

Yes. Toddler blankets are usually larger to provide more coverage for growing children. A common toddler blanket size is around 70 × 90 cm.
What size blanket is safest for a newborn?

What’s the difference between a blanket and a comforter?
Blankets are designed mainly for warmth, while comforters are smaller soothing items designed for cuddling and emotional comfort.
The Best Blanket Is Usually the One That Goes Everywhere
While sizing guides are helpful, most parents quickly discover that babies tend to choose favourites based on softness, familiarity and comfort rather than measurements.
It’s the blanket that lives in the buggy basket.
The one that gets dragged into the living room every evening.
The one that somehow becomes part of every nap, cuddle and car journey.
And honestly, those are usually the blankets that end up most loved.
