Quilt calculators
The two questions every quilter asks at the cutting table: "how much backing?" and "how many fat quarters?" Answered in seconds, with honest math and conservative 40" usable width. Estimates — always buy a touch extra for directional prints.
Backing & binding calculator
Assumes 40" usable width of fabric, 4" backing overhang per side, 2.5" binding strips.
Backing
4.25 yd
2 vertical panels of 74" each, seamed side by side.
Binding
0.5 yd
7 strips × 2.5" WOF (perimeter ≈ 250" incl. corners and joins).
Fat quarter math
How many 18" × 22" fat quarters for a simple square-block top. Cut size = finished block + ½" seam allowance.
Fat quarters needed
17
99 blocks total (9 × 11) cut at 6.5" · each fat quarter yields 6 blocks.
Tip: add 1–2 extra FQs for fussy cutting, mistakes, and the scrap bin — future you says thanks.
