Needlepoint wool calculator
Enter your stitch count and canvas mesh — get thread length, skeins, and hanks for Appleton crewel and tapestry wool or DMC stranded cotton, with basketweave and strand-count adjustments built in.
Wool Calculator
Stitches in this color (not the whole design) — your chart's legend lists per-color counts.
Crewel: 2 strands on 13 mesh, 1 on 18, 3 on 10 — test a square on your canvas margin.
Basketweave's woven back uses ~10% more thread.
Appleton put-ups
Crewel (2-ply): 25 m skeins, 180 m hanks. Tapestry (4-ply): 10 m skeins, 55 m hanks. Buy hanks for backgrounds — per meter they're roughly a third cheaper. All 430 shades are in the Appleton color chart; coverage pairings per mesh are in the thread guide.
Results
10,000 tent stitches on 13 mesh ≈ 0.77 cm of thread path each (+10% for basketweave) × 2 strands = 169.2 m. With 20% margin, that's 8.12 × 25 m skeins. Estimates only — fiber, tension, and mesh vary, so stitch a test square before buying a background's worth.
| Mesh | Per sq. inch | Strands | Sq. in / skein |
|---|---|---|---|
| 10 mesh | 1.0 m | 3 | ~8 |
| 12 mesh | 1.2 m | 2 | ~10 |
| 13 mesh | 1.3 m | 2 | ~9 |
| 14 mesh | 1.4 m | 2 | ~8 |
| 18 mesh | 1.8 m | 1 | ~13 |
Continental tent stitch, typical strand counts for Appleton crewel (2-ply), 25 m skeins. One square inch on 13 mesh ≈ 1.3 m of thread path.
The estimate behind the calculator: one tent stitch uses about 10 ÷ mesh centimeters of thread — front pass plus its share of the back — so a square inch of 13 mesh (169 stitches) consumes roughly 1.3 meters of thread path. Thread two strands of crewel together and the strand-length doubles. Add 20% for anchoring, waste, and tension variation, divide by the skein length, and that's your shopping list.
Worked example
A 10,000-stitch background on 13 mesh in Appleton crewel at 2 strands, basketweave:
- Thread path: 10,000 × 0.77 cm × 1.1 (basketweave) ≈ 85 m
- Strand length: 85 m × 2 strands = 169 m
- With 20% margin: ≈ 203 m
- To buy: 203 ÷ 25 m = 8.1 → 9 crewel skeins, or a 180 m hank plus one skein
The hank option is the one shops will suggest for backgrounds — Appleton sells crewel in 25 m skeins and 180 m hanks, tapestry wool in 10 m skeins and 55 m hanks, and hanks are the better per-meter buy.
Which thread for which mesh
Tapestry wool (single strand) suits 10–13 mesh. Crewel wool scales across everything — 3 strands on 10 mesh, 2 on 13, 1 on 18. DMC stranded cotton only covers 18 mesh and finer, at 3–4 strands. The thread guide has the full pairing table including silks and perle cottons; whatever you pick, the one-inch test square on your canvas margin is the step that catches coverage problems before you've bought a background's worth.
Reading stitch counts off a chart
Charts made in the needlepoint pattern maker export a legend with per-color stitch counts — paste each color's count into the calculator for a full shopping list. For painted canvases, estimate each color's share of the design area in square inches and use the reference table's per-square-inch figures instead.
