A king-size blanket is typically 108-120 inches wide and 90-100 inches long, which equals 3.0-3.3 yards in width and 2.5-2.8 yards in length.

A standard king-size blanket measures about 108x90 inches to 120x100 inches. Converting inches to yards (1 yard = 36 inches), the width spans 3.0-3.3 yards, while the length covers 2.5-2.8 yards. Exact dimensions vary by manufacturer, but most fall within this range.

King-Size Blanket Dimensions in Yards

  • Width: 108-120 inches = 3.0-3.3 yards
  • Length: 90-100 inches = 2.5-2.8 yards
  • Total fabric (approx.): 7.5-9.0 square yards (width × length)

Comparison: Blanket Sizes in Yards

Blanket Size Width (Yards) Length (Yards) Total Fabric (Sq. Yards)
Twin 1.5-2.0 2.5-3.0 3.8-6.0
Queen 2.5-2.8 2.8-3.0 7.0-8.4
King 3.0-3.3 2.5-2.8 7.5-9.0

Factors Affecting Yardage

  • Material type: Knit fabrics may require more yardage due to stretch.
  • Blanket style: Oversized or weighted blankets often exceed standard dimensions.
  • Seam allowance: Adding 0.1-0.3 yards for hems or borders.
  • Custom sizing: Non-standard lengths/widths alter total yardage needs.

How to Calculate Yardage for DIY Blankets

  1. Measure desired width and length in inches.
  2. Divide each by 36 to convert to yards.
  3. Multiply results for total square yards needed.
  4. Add 10-15% extra for shrinkage or pattern matching.

Common King-Size Blanket Materials & Yardage Needs

  • Cotton: 3.0-3.3 yards (width) × 2.5-2.8 yards (length); minimal stretch.
  • Fleece: 2.8-3.0 yards (width) due to wider fabric bolts (often 60" wide).
  • Wool: 3.3-3.5 yards (width) to account for fulling/shrinkage.
  • Minky: 3.0-3.3 yards (width), but may require lining (double yardage).
