Cross Stitch Floss Calculator

Estimate how many skeins of embroidery floss your project needs from the stitch count, fabric and strands you use — so you can buy enough in one dye lot without overspending.

How much floss does a cross stitch project need?

Floss use comes down to three things: how many stitches you make, how big each stitch is (the fabric count), and how many strands you pull. A standard skein of stranded cotton is about 8 metres of 6-strand thread. Split it into the 2 strands most people stitch with, and a single skein covers on the order of 1,700 full cross stitches on 14-count Aida. Move to a higher count and each stitch is smaller, so the same skein goes further; use more strands and it runs out sooner. This calculator starts from that 14-count baseline and scales it to the fabric and strand count you choose.

Because floss is sold one colour at a time, the practical answer is always rounded up. You can't buy two-thirds of a skein of a colour, and you can't mix dye lots without a visible shift, so entering your number of colours sets a sensible floor of one skein each. For a colour that covers most of the design — a big sky or background — buy an extra skein up front; it's cheap insurance against running short halfway through. Treat the number above as a confident starting point, not a guarantee, and you'll rarely be caught out.

Frequently asked questions

How many stitches does one skein of floss cover?
It depends on the fabric count and how many strands you use. A standard 8-metre (6-strand) skein worked with 2 strands covers roughly 1,700 full cross stitches on 14 count — more on higher counts because the stitches are smaller. This calculator scales that estimate to your fabric and strands.
How many strands of floss do I use for cross stitch?
Two strands is the most common for full coverage on 14–16 count. Use 3 strands on 11 count for a fuller look, and 1–2 strands on 18–22 count. Backstitch outlines usually use 1 strand.
Why does the calculator round up per colour?
Floss is sold by the skein, one colour at a time, so you can never buy a fraction of a skein of a colour. If you enter the number of colours, the estimate never drops below one skein per colour — and it’s always wise to buy a little extra in the same dye lot.
Is this estimate exact?
No estimate can be exact — thread use varies with your tension, how often you start and stop, railroading, and fractional stitches. Treat the result as a solid planning figure and round up, especially for a colour used across the whole design.
