A twin-size blanket is typically 3-4 yards of fabric (90-120 inches long).

A standard twin blanket measures 66x90 inches (1.7x2.3 meters). For sewing, you'll need 3-4 yards of 45"-60" wide fabric, depending on desired drop length. Pre-made twin blankets vary slightly by brand but average 1.5-2 yards in total fabric area.

Key Measurements for Twin Blankets

  • Finished size: 66" (width) x 90" (length)
  • Fabric width: 45"-60" (common bolt widths)
  • Fabric needed (with 10" drop):
    • 45" fabric: 4 yards (seamed)
    • 60" fabric: 3 yards (no seams)
  • Pre-made blanket area: ~1.5-2 square yards

Fabric Yardage Comparison by Blanket Type

Blanket Size Finished Dimensions Fabric Width Yards Needed (No Seams) Yards Needed (Seamed)
Twin 66" x 90" 60" 3 N/A
Twin 66" x 90" 45" N/A 4
Full/Double 80" x 90" 60" 4 N/A
Queen 90" x 95" 60" 5 6 (seamed width)

Factors Affecting Yardage

  • Fabric width: Wider fabric (60") reduces seams and waste.
  • Drop length: Extra 10"-20" for overhang adds 0.5-1 yard.
  • Pattern matching: Directional prints may require 10-20% extra fabric.
  • Binding/hem: Add 0.5 yard for self-fabric borders.
  • Pre-made blankets: Yards vary by material thickness (e.g., fleece vs. cotton).

How to Calculate Yardage for a Twin Blanket

  1. Determine finished length: Standard is 90", but add drop (e.g., +10" = 100" total).
  2. Convert to yards: 100" ÷ 36 = 2.78 yards (round up to 3).
  3. Check fabric width:
    • If fabric is 60" wide, 3 yards covers the 66" twin width.
    • If fabric is 45" wide, buy 4 yards (seam two lengths).
  4. Add 10% for shrinkage/errors: 3 yards → 3.3 yards.

Common Fabric Types & Yardage Adjustments

  • Cotton/Quilting: Stable; no extra needed.
  • Fleece: Stretchy; add 0.5 yard for stability.
  • Flannel: Shrinks 5-10%; pre-wash or add 0.5 yard.
  • Minky: Slippery; add 1 yard for cutting errors.
