Cross Stitch Skein Calculator
Work out how many skeins to buy before you shop. Enter the design size, the number of colors and the average share of the design each color covers to get skeins per color, total skeins and an estimated cost.

How the skein estimate works
Stitches per color = total stitches × coverage. Each full stitch uses about 0.5 inch of each strand, and an 8 m skein holds 1,890 inches of single strand, so one skein covers about 1,643 stitches with 2 strands after a 15% buffer. Skeins are rounded up for each color.
Coverage is an average. If a background fills 40% of the design and six detail colors share the rest, estimate the background on its own with 40% and one color, then the detail colors with about 10% each. The skein guide works through this example.
Using your pattern's color key
Many charts list the stitch count or skeins for each DMC number in the key. Use those figures where they exist; this calculator is for patterns that only give the overall size, or for designs you made yourself in the pattern creator.
Organizing skeins
Wind each skein onto a card or plastic bobbin and write the color number on it. Store bobbins in number order in a divided box, and keep the paper band until the number is written down.
Estimating coverage when the pattern does not say
Coverage is the share of the design one color fills, and it is the only figure here you have to judge rather than read. Charts rarely state it. Three ways to get close, in order of how much effort they take:
- Look at the printed chart from a distance. The dominant color is usually obvious, and estimating it at 30, 40 or 50 percent is accurate enough, because the result is rounded up to whole skeins anyway.
- Split the remainder evenly. If the background is 40% and eight colors share the rest, 7.5% each is a reasonable default. Outline and accent colors almost always come in under one skein.
- Count squares on the chart grid. For a color you are unsure about, count the symbols in a ten by ten block of the busiest area and scale up. Slow, but it settles the one color that would cost you a second trip to the shop.
Errors here matter less than they look. A color estimated at 10% instead of 15% still lands inside one skein at most project sizes, and the 15% waste buffer absorbs the difference. The estimate that is worth getting right is the background, because it is the only one likely to need three or four skeins of the same dye lot.
Which of the three thread tools you need
They start from different information. Pick the one that matches what your pattern actually tells you.
How much thread does this design use in total?
You know the stitch count and the strands, and you want a length and a formula you can check.
How many skeins of each color from my chart key?
You have a color key with a stitch count beside each shade and you are writing a shopping list.
How many skeins altogether, and what will they cost?
The pattern only gives a size and a number of colors, so you are estimating from coverage.
