Embroidery Floss Calculator

On 14-count each stitch sits in a 0.18 cm square, and one cross is two diagonals of it — 0.51 cm. Travelling on the back and securing the starts and ends eats roughly as much again, so budget about 1.03 cm per stitch per strand. Two strands over 1,000 stitches comes to 20.5 m.

Formula

Floss length = Stitch count × Strands × 4 × √2 × 2.54 ÷ Fabric count ÷ 100

A DMC skein is six strands of 8 m, or 48 m of single strand, which covers about 2,300 stitches at two strands. Long jumps on the back and frequent colour changes burn through it much faster, so allow extra for a colour scattered across the whole chart.

Frequently asked questions

Q. How is Embroidery Floss Calculator calculated?

Floss length = Stitch count × Strands × 4 × √2 × 2.54 ÷ Fabric count ÷ 100 — On 14-count each stitch sits in a 0.18 cm square, and one cross is two diagonals of it — 0.51 cm. Travelling on the back and securing the starts and ends eats roughly as much again, so budget about 1.03 cm per stitch per strand. Two strands over 1,000 stitches comes to 20.5 m.

Q. Can you walk through an example?

With Stitch count 1,000sts, Strands 2, Fabric count 14, the answer is Floss length 20.5m.

Q. What do I need to enter?

Enter Stitch count, Strands, Fabric count. The result recalculates as you type, and an empty box counts as zero.

Q. How much does the answer move if I change a number?

Changing only Stitch count (sts) moves the answer to Stitch count (sts) 500 → Floss length (m) 10.3 and Stitch count (sts) 2,000 → Floss length (m) 41.1. The table below lays out five steps.

Q. How are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

Q. Anything to watch out for?

A DMC skein is six strands of 8 m, or 48 m of single strand, which covers about 2,300 stitches at two strands. Long jumps on the back and frequent colour changes burn through it much faster, so allow extra for a colour scattered across the whole chart.
