Choosing a blanket size

Start with who or what the blanket is for. Baby blankets are sized for a crib, stroller or car seat, throws for a person on a sofa, and bed blankets for a mattress. For beds, a fixed chart is less useful than the mattress itself, which is why the calculator builds the size from the mattress plus the drop you want over the sides.

A drop of 8–12 inches suits a blanket that sits on top of a duvet. For a bedspread that reaches the floor, measure from the top of the mattress to the floor and use that as the drop.

From size to stitches

Gauge is everything on a blanket: half a stitch per 4 inches more or less changes a 50 inch throw by nearly 3 inches. Wash and dry your swatch the way you will treat the blanket, then measure. If you plan a border, subtract its width from each edge before you calculate, and see roughly how much yarn you need with the yarn calculator. Charting a picture blanket? Plan it on C2C graph paper or turn a photo into a graph with the photo to pattern maker.

How to use it

Pick a blanket from the list, choose Fit a bed to size one from a mattress, or enter your own size.
Choose knitting, crochet or C2C.
Enter your gauge from a washed swatch: stitches and rows over 4 inches or 10 cm, or C2C tiles over 4 inches.
If your stitch pattern repeats, enter the multiple so the cast-on fits it exactly.

Questions

What size is a baby blanket?

There is no single standard. A receiving or swaddle blanket is usually about 36 × 36 inches, a stroller or car seat blanket about 30 × 35 inches, and a crib blanket about 45 × 60 inches. Blankets for babies in the NICU are often much smaller, around 24 inches square, so check with the hospital or charity first.

What size is a throw blanket?

Around 50 × 60 inches is the most common throw size and covers one adult on a sofa. A lapghan, for someone sitting in a chair, is smaller, about 36 × 48 inches.

How big should a queen size blanket be?

A queen mattress is 60 × 80 inches. With a 12 inch drop on both sides and the foot, a queen blanket is about 84 × 92 inches. Use Fit a bed to choose your own drop and add a pillow tuck.

How many stitches do I cast on for a blanket?

Multiply the width by your stitches per inch. At 18 stitches per 4 inches (4.5 per inch), a 50 inch throw needs about 225 stitches. The calculator also rounds to your stitch pattern’s multiple.

How many C2C tiles do I need for a blanket?

Multiply the width and length by your tiles per inch. A typical worsted C2C tile is about 4 tiles per 4 inches, so a 50 × 60 inch throw is about 50 × 60 tiles.
