When making a crochet baby blanket, using granny squares is a fast, flexible and attractive choice. You can either make one large square or use many smaller squares joined together with a border all round.
Here you’ll find all the info you need to choose the right size blanket to make, plus five bright and happy designs with free patterns that babies and parents are bound to love.
Sizing for granny square baby blankets
If you try researching the perfect baby blanket size, you’ll be overwhelmed with loads of different opinions about types and sizes. Baby blankets are not as simple as you thought!
But don’t be put off. The important thing to remember is that there is no wrong size, and your handmade gift will be cherished by both the new parents and the baby!
This is not a complete list by any means, but it includes the various names of different types of baby blanket and the approximate sizes, from largest to smallest.
Babies don’t stay small very long! For a blanket to get a good amount of use, choose a granny square baby blanket 45″ x 60″. This is a bit big for swaddling, but it can be used on a crib and then as a cover up for a child during naps and cuddle times. This size of blanket is also perfect as a lap-ghan or a wheelchair blanket for adult use.
Cribs and cots do not have a standard size, so if you know what size crib you are making for, go with those measurements. Otherwise, a blanket 30″ – 36″ x 50″– 54″ will work well.
Traditionally the blanket used to wrap a baby in when first born, this is a multi-use blanket for cribs, in the stroller, during naps as well as for swaddling and comfort as the baby grows. A receiving blanket is 34″– 36″ square.
A slightly smaller baby blanket used to wrap a baby gently by simulating the close cuddle in the womb. A good starting size is 30″ square, but a 34″ square would double as both a receiving and a swaddling blanket.
Used when out and about, this needs to be 24″ – 26″ x 30″. A granny square baby blanket made from small, individual motifs joined together is ideal.
Bassinet or cradle blanket
This one is for covering a new baby when it first comes home. A stroller blanket can double as a bassinet blanket, or you could go slightly smaller: 16″ x 30″. A very fast granny square blanket to whip up for a last-minute gift!
Used for premature babies, these super-small blankets can range from 15″ square to 24″ square (or a rectangle within that range). If you want to make blankets for a special care baby unit, check with the parents or the hospital first. A granny square baby blanket may not be suitable because of the holes, which can trap breathing and feeding tubes, fingers and even arms and legs.
A tiny comfort blanket used for snuggling and security — picture a baby who won’t go anywhere without it! This is the smallest blanket at around 18″ square.

A pastel granny square baby blanket
This one-square design from Lauren Brown of Daisy Cottage Designs uses soft sea green, white and neutral stone shades to make an 18″ square lovey blanket. But this blanket could easily be made larger with more rounds before the simple border, and you could switch out the colors. I love this design because it’s striking, useful and because you are using larger bands of color — not too many pesky ends to weave in! Get free pattern here.

Stephanie made this when she was pregnant and spent some quiet time thinking about the baby that was wriggling away as she worked the 36 rounds. What a great way to make something beautiful and useful while preparing to welcome a new baby into the family!

Mitered Granny Square
This is an unusual take on the traditional granny square, but it’s no more difficult to do. Made by Sue Rivers of Crochet Again, it combines just five bright colors in offset mitered squares all joined in white for maximum impact. Sue made her blanket with six squares on each side (36 in total), but you could make this style into any size granny square baby blanket. Follow the pattern here.
