You've decided to make a baby quilt because, duh, new parents love receiving them and quilters love making them! But how big should you make yours?
Honestly, there isn't one size that you must adhere to. Your baby quilt can be as big or small as you like! That said, these are the common sizes many quilters refer to when pulling together their own projects.
30" x 30"
This size is perfect for newborns. Although it won't wrap around baby forever (sounds like a good excuse to make another quilt!), it can have a second life as a play mat or just-in-case blankie that goes on road trips and picnics. Oh, and since you only need one yard of fabric for the backing, 30" x 30" quilts are a seriously cost-effective creation.
30" x 40"
If rectangles are more your style than squares, this longer quilt gives baby plenty of room to grow. Plus, you can still easily use yardage for the backing without having to piece it .
36" x 52"
It's become a standard size thanks to its ability to fit well over a crib mattress (those typically measure around 28" x 52"), but remember, the American Association of Pediatrics recommends a bare crib without quilts or blankets for infant safety. So while you may see them labeled as crib quilts, they're actually better for supervised tummy-time and other wide-awake activities.
If these sizes don't feel quite right to you, don't sweat it! Anything larger than 36" also makes a great floor covering for babies on the move — and larger quilts are sure to be used as the child grows and begins sleeping with covers.
