Blanket sizes are not standardised the way mattresses are — every designer rounds differently. These are the dimensions most published crochet patterns use, in both inches and centimeters, with a yardage estimate for each one so you know what you are committing to before you buy the yarn. Pick a size below to get your own numbers and print them.

Crochet blanket size chart
Yardage is the amount to buy in double crochet, including a 10 % allowance for tails, joining and a modest border. Single crochet needs about 21 % more; half double about 7 % more. Squares column assumes 6 inch squares.

How the yardage is worked out
Yarn consumption for a flat blanket is an area problem, not a length problem. Every LTK tool uses the same model, so the blanket calculator, the yarn calculator and this chart always agree:
yards to buy = area in square inches × yards per square inch × weight multiplier × 1.10
The yards-per-square-inch figures come from measuring worsted swatches and unravelling them: 0.832 for single crochet, 0.731 for half double, 0.686 for double crochet, and 0.65 for joined granny squares. Taller stitches cover more area per yard, which is why a double crochet blanket is roughly a fifth cheaper in yarn than the same blanket in single crochet.
The weight multiplier scales that worsted figure to other yarns, using the Craft Yarn Council gauge midpoints: super fine 2.12, fine 1.44, DK 1.16, worsted 1.00, bulky 0.76, super bulky 0.64. The final ×1.10 is the buy allowance — tails, joining, a modest border and the ball you would otherwise run out of two rows from the end.
Two assumptions are baked in and worth stating plainly. First, this assumes you crochet at roughly the standard gauge for your yarn; if you work tightly you will use more. Second, it does not include a deep decorative border — add 5 to 10 % for anything beyond a single round of single crochet.
Worked example: how much yarn for a 50 × 60 blanket?
A throw at 50 by 60 inches is the most-made blanket size there is, so here it is start to finish.
- Area: 50 × 60 = 3,000 square inches
- Double crochet, worsted: 3,000 × 0.686 × 1.00 × 1.10 = 2,264 yards to buy
- At roughly 200 yards per 100 g worsted ball, that is 12 balls
- Same blanket in single crochet: 3,000 × 0.832 × 1.10 = 2,746 yards, about 14 balls
- Same blanket in bulky: 3,000 × 0.686 × 0.76 × 1.10 = 1,721 yards — but bulky balls hold far less, around 120 yards, so that is 15 balls
That last line surprises people. Bulky yarn needs fewer yards but usually more balls, and it almost always costs more per finished blanket. It is faster, not cheaper.
In 6-inch granny squares, the same throw is 9 squares across by 10 down — 90 squares, about 2,317 yards once joining and a border are counted.
Questions people ask
How many yards of yarn to crochet a 50x60 blanket?
About 2,264 yards in double crochet with worsted yarn, including the 10 % buy allowance. In single crochet it is about 2,746 yards, and in bulky about 1,721 yards.
What is the standard crochet blanket size?
There is no single standard, but the sizes most patterns use are lovey 12 × 12, preemie 18 × 24, baby 30 × 36, receiving 36 × 36, lapghan 36 × 48, toddler 42 × 52, crib 45 × 60, throw 50 × 60, twin 66 × 90, full 80 × 90, queen 90 × 108 and king 108 × 108 inches. A 50 × 60 throw is the most common size sold and given as a gift.
What size should a baby blanket be?
30 × 36 inches for a stroller or car seat, 36 × 36 for swaddling, 45 × 60 for a crib. Loose crochet blankets should not be left in a sleeping baby's crib — make them for tummy time, prams and laps.
How do I convert blanket sizes from inches to cm?
Multiply inches by 2.54. A 50 × 60 inch throw is 127 × 152 cm. The chart above lists both for every size, so you can print it and stop converting.
How much bigger should a blanket be than the bed?
A blanket made to the mattress dimensions sits on top with no drape. For a bedspread look, add 10 to 12 inches on each side you want to hang — which is why a twin blanket at 66 inches is 27 inches wider than a 39 inch twin mattress. For a throw over the foot of the bed, mattress width is fine.
