Blanket Drape Secret: Blankets made with double crochet (dc) or moss stitch have much softer drape and fold nicely over arms or beds compared to single crochet (sc), which creates a stiff, cardboard-like fabric unless worked with a hook 2-3 sizes larger than recommended.
How to use the blanket size calculator
- Row 1Tap a blanket size (baby, crib, throw, twin, queen and more) or enter custom dimensions.
- Row 2Choose your yarn weight: DK, worsted or bulky.
- Row 3Choose your stitch: double, half double, single or treble crochet.
- Row 4Read the starting stitches, rows, estimated yardage and skeins, plus how many 6-inch granny squares would cover the same area.
Standard blanket sizes
There's no single official standard for crochet blankets, so sizes vary a little between sources. These presets are common sizes; the bed sizes cover a standard US mattress with a generous drop on each side:
| Blanket | Size | Covers |
|---|---|---|
| Lovey | 12 × 12 in | A small comfort square |
| Baby / stroller | 30 × 35 in | Strollers and car seats |
| Lapghan | 36 × 48 in | A lap, without dragging on the floor |
| Crib | 36 × 54 in | A standard crib mattress |
| Toddler | 42 × 52 in | Toddler beds and play mats |
| Throw | 50 × 60 in | A sofa; the most popular size |
| Twin | 66 × 90 in | 38 × 75 in mattress, about 14 in drop each side |
| Full | 80 × 90 in | 54 × 75 in mattress, about 13 in drop |
| Queen | 90 × 96 in | 60 × 80 in mattress, about 15 in drop |
| King | 108 × 96 in | 76 × 80 in mattress, about 16 in drop |
Worked example
A throw (50 × 60 in) in worsted and double crochet:
- The calculator uses a typical worsted gauge of 3.5 stitches and 2.2 rows per inch, so about 175 stitches across and 132 rows.
- Yardage: 3,000 square inches × 0.75 = about 2,250 yards.
- Skeins: at a typical 200 yards per 100 g ball, 12 skeins.
- Granny square equivalent: 3,000 ÷ 36 = about 83 six-inch squares.
The stitch and row counts use a typical gauge for the yarn weight, so treat them as a guide. For exact numbers, measure your swatch and use the gauge calculator. Our blanket yardage guide has the full yarn chart for every size.
The formula
Stitches = width × typical stitches per inch for the yarn weight. Rows = length × typical rows per inch. Yardage = width × length × yards per sq in (DK 0.87, worsted 0.75, bulky 0.57) × stitch factor (sc 1.22, hdc 1.08, dc 1.0, tr 0.88). Skeins = yardage ÷ typical yards per 100 g ball.
Tips
- For a bed blanket, measure the mattress and add the drop you want on each side and at the foot.
- Add 10–15% to the yardage for the border and a safety margin.
- Big blankets take a lot of yarn. Check the cost before you start, and buy one dye lot.
- Want a smaller version of a pattern? Choose a smaller preset and recalculate the stitch counts.
