Crochet Blanket Sizes: Size Chart, Guide and C2C Blocks

Crochet blanket sizes from lovey to king, and what each one means in single crochet stitches, C2C blocks, filet squares and yarn. Every number in the tables is calculated by the same engine as the crochet pattern maker.

Crochet blanket size chart

Blanket sizes are conventions, not rules, and pattern designers vary them by a few inches. This crochet blanket size chart uses the Sleep Foundation's blanket size guide for the bed sizes; lovey, baby and throw are the sizes most crochet patterns use. Centimeters are rounded to the nearest whole number.

Sources: Sleep Foundation, "Blanket Sizes 101" (twin, full, queen, king); lovey, baby and throw from common crochet pattern sizes.

Crochet blanket size guide: choosing a size

A bed blanket is usually the mattress plus a drop on three sides. A twin mattress is 38 × 75 in, so a 65 × 90 in twin blanket drops about 13 in on each side; if you want it to tuck in, add more length rather than width. Throws are for sofas and laps and do not need to match a bed at all. As a crochet blanket size guide for gifts: a lovey fits in a diaper bag, a baby blanket covers a crib mattress (28 × 52 in) across its width, and a throw covers one adult on a sofa from shoulders to feet.

C2C blanket size chart: blocks for every size

For corner-to-corner blankets the useful number is blocks across and blocks down, which is also the chart size you enter in the C2C graph maker. Blocks = size ÷ block size. Worsted dc blocks are usually close to 1 in (2.5 cm); measure four blocks of your swatch and pick the nearest size here. The table below works as a C2C blanket size calculator: it recalculates when you change the block size.

Diagonal rows = blocks across + blocks down − 1. Yards scale with block size (bigger blocks use more yarn each, fewer blocks overall). Estimates — buy about 10% extra.

Two checks before you chart: the maker handles up to 300 blocks in each direction, enough for a king at 0.75 in blocks; and a C2C graph from a photo needs about 50 blocks across before faces become recognizable, so lovey-size C2C works best for simple shapes and letters.

One picture at two blanket sizes

Size changes more than yardage: it decides how much detail a picture keeps. Below, the maker's engine charts the same heart at the C2C width of a baby blanket (30 blocks) and of a throw (50 blocks), both with 1 in blocks and 3 colors. The baby version has 900 blocks in 59 diagonal rows; the throw version has 2,500 blocks in 99 diagonal rows and a visibly smoother curve and outline.

The heart is square and both blankets are taller than wide, so the rest of the length is plain border rows. Charting the border into the picture (or cropping the photo to the blanket's proportions before you load it) keeps the motif centered.

Single crochet stitches and rows for each size

Single crochet graphgans show the most detail but need many more stitches. At a firm worsted gauge of 16 stitches × 18 rows per 4 in:

The chart maker stops at 300 × 300, so twin and larger single crochet blankets are made in panels or charted at a coarser gauge.

Compare a throw: 200 × 270 = 54,000 single crochet stitches against 50 × 60 = 3,000 C2C blocks. Single crochet also uses more yarn per square inch, which is why most photo throws are C2C and most detailed portraits stay at pillow or wall-hanging size.

Filet squares for each size

Filet blankets and bedspreads are lighter and lacier. In worsted yarn a filet square is about 2 cm, or 5 squares per 10 cm; in size 10 cotton thread the same blanket would need about three times as many squares each way. The foundation chain is 3 × squares + 3.

How the yarn numbers are estimated

Yardage comes from the crochet yarn calculator model: stitches or blocks from the size and gauge, times the yarn one stitch uses, scaled from reference rates in worsted (about 1.1 yd per square inch for single crochet, 0.8 for double crochet and 0.98 for C2C blocks). Skeins assume 364 yd per skein and include 10% extra. Your tension can move the real number by 10 to 15% either way, so weigh a swatch if the budget is tight.

From a size to a chart

Pick the size, then decide the stitch: C2C for a fast blanket, single crochet or tapestry for detail. In the maker, switch Set width by to Finished width, enter the blanket width and your gauge, and the chart is sized for you; the rows follow your picture's proportions. If the picture is square and the blanket is a rectangle, crop the picture first or add a border of plain rows.
