How long is a standard skein of embroidery floss?

A standard DMC or Anchor embroidery floss skein is 8 metres (8.7 yards). Each skein has 6 strands that can be separated. Most cross stitch uses 2 strands at a time.

How many strands should I use?

On 14-count Aida, use 2 strands for cross stitch and 1 strand for backstitch. On 11-count, use 3 strands. On 18-count, use 1-2 strands. More strands give fuller coverage but use more thread.

How do I estimate coverage percentage?

Full coverage designs (no fabric showing) are 90-100%. Samplers and motif designs with open areas are 40-60%. Simple borders and lettering are 10-30%. Check your pattern chart to estimate the stitched area.

Should I buy extra skeins?

Always buy 1-2 extra skeins of each colour, especially for larger projects. Dye lots can vary, so buying all skeins at once ensures colour consistency. Extra thread is useful for repairs or matching projects.

How We Calculate This

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 × Strands × 2 (top and bottom)

Skeins per colour = ceil(Total thread ÷ Colours ÷ 8m)
