Quilt Finishing Calculator — Batting, Backing, Binding & Thread

~1 minute

Enter your finished quilt width and length, batting type, backing fabric width, binding cut width, and a quilting method. The calculator returns a single shopping list: batting size (with a common pre-cut recommendation), backing yardage, binding yardage, and a thread estimate. Batting, backing, binding, and thread use the same verified formulas as the dedicated calculators.

What this calculator determines

It calculates a single shopping list of batting, backing, binding, and thread to finish a quilt, using the same formulas as the dedicated calculators.

Examples

50″ × 65″ quilt, packaged batting, straight-line thread

50″ × 65″, packaged batting, 4″ overage, 42″ backing, 2.5″ binding, straight-line 1″ spacing

Calculation

  1. Batting: 58″ × 73″ → Twin (72×90) pre-cut
  2. Backing: crosswise 2 panels × 58″ = 116″ → 3.25 yd
  3. Binding: perimeter 230 + 10 = 240″ → 6 strips → 0.5 yd
  4. Thread: 50 lines × 65″ = 3250″ → 90.3 yd → 1 spool (500 yd)

Batting 58×73 (Twin), backing 3.25 yd, binding 0.5 yd, thread 90.3 yd (1 spool)

60″ × 72″ quilt, roll batting 96″, cross-hatch thread

60″ × 72″, 96″ roll batting, 4″ overage, 42″ backing, 2.5″ binding, cross-hatch 1″ spacing

Calculation

  1. Batting: 68″ × 80″ → off 96″ roll, 80″ linear → 2.25 yd
  2. Backing: crosswise 2 panels × 68″ = 136″ → 3.875 yd
  3. Binding: perimeter 264 + 10 = 274″ → 7 strips → 0.625 yd
  4. Thread: 60×72 + 72×60 = 8640″ → 240 yd → 1 spool

Batting 68×80 (2.25 yd roll), backing 3.875 yd, binding 0.625 yd, thread 240 yd

Assumptions & Conventions

Overage
Batting and backing use a 4″ per-side overage (default) for quilting take-up and longarm loading.
Matching formulas
Batting, backing, binding, and thread use the same verified formulas as their dedicated calculators; no new formulas are introduced.
Purchase rounding
All yardage is rounded up to the next 1/8 yard.
