Crochet Blanket Size Chart & Yarn Requirements
Planning a new crochet blanket project is an exciting creative endeavor. You pick out the perfect yarn blend, the ideal color palette, and a gorgeous stitch pattern. However, before you make your first slip knot, you must determine two critical parameters: the target dimensions of the blanket and how much yarn you need to purchase. Blanket sizes are not standardized, and stitch selection can double the required yardage. In this comprehensive guide, we provide a complete crochet blanket size chart and show you how to estimate yarn yardage per stitch.

1. Standard Crochet Blanket Dimensions
Refer to this chart for standard dimensions of various blanket styles, from small baby blankets to large bed spreads:
| Blanket Type | Dimensions (Inches) | Dimensions (Centimeters) | Primary Purpose |
|---|---|---|---|
| Lovey | 12" × 12" | 30 × 30 cm | Small security blanket for infants. |
| Baby Blanket (Receiving) | 40" × 40" | 100 × 100 cm | Standard swaddling and stroller cover size. |
| Lapghan / Wheelchair | 36" × 48" | 90 × 120 cm | Comfortable lap cover for sitting. |
| Throw Blanket | 50" × 60" | 127 × 152 cm | Standard couch throw blanket size. |
| Queen Size Bed | 90" × 90" | 228 × 228 cm | Full coverage for a queen size bed. |
| King Size Bed | 108" × 90" | 274 × 228 cm | Full coverage for a king size bed. |
2. How Stitch Selection Impacts Yarn Consumption
Two blankets with the exact same dimensions can require vastly different amounts of yarn depending on the **stitch type**:
- Single Crochet (SC): Produces a dense, solid fabric. Moderately low yarn consumption.
- Double Crochet (DC) / Treble (TR): Produces a looser, taller stitch. Very efficient yardage consumption.
- Puff / Bubble / Waffle Stitches (Yarn Hogs): These texture-rich stitches require wrapping yarn multiple times in a single stitch. They can consume **2 to 3 times more yarn** than a simple double crochet stitch.
3. Estimating Yardage Based on Size
Here is a baseline estimate of yardage requirements for a **standard Worsted (Weight 4) yarn** using a double crochet (DC) stitch:
- Baby Blanket (30" × 36"): 700 - 900 Yards.
- Lapghan (36" × 48"): 1,100 - 1,400 Yards.
- Throw (50" × 60"): 1,900 - 2,200 Yards.
- Queen Bed (90" × 90"): 4,200 - 4,800 Yards.
4. Accounting for Blanket Borders
Don't forget the **border**! Adding a border is a great way to clean up raw edges, but it can consume significant yardage.
As a rule of thumb, add a **10% safety margin** to your yarn calculations to cover a standard 2-row border, and a **15% to 20% margin** if you plan to add a wide, textured border or tassels.
