Embroidery Floss Calculator — Skeins Needed

Thread consumption is estimated from the design area, stitch density (from fabric count), coverage percentage, and number of strands used.

The formula

Stitches = Design area × Coverage% × Stitches per cm²

Thread per stitch = Cross size × 7.7 × Strands (single-strand length, anchored to ~0.55 in / 1.4 cm of 2-strand working thread per cross on 14-count Aida — covering both diagonals, back-of-fabric travel and per-pass waste)

Skeins per colour = ceil(Thread per colour × 1.15 waste ÷ (Skein length × 6))

Thread per stitch is measured in single-strand length, so it is divided by the single-strand capacity of a skein. A standard 8 m skein holds 8 m of 6-strand floss = 48 m of single-strand length (24 m of usable 2-strand working thread). On 14-count Aida with 2 strands this works out to roughly 1,500 stitches per skein. A 15% buffer covers starts, ends and frogging, and each colour rounds up to a whole skein.
