400 ends × 3.5 yd (3 yd + loom waste) = 1,400 yd warp. Weft: 18 in finished width × 20 PPI × 108 in length = ~360 yd.

150 ends × 3 yd (2.5 + loom waste) = 450 yd warp. Weft: 9 in width × 15 PPI × ~80 in woven length = ~113 yd.
Use this page to calculate warp yardage, weft yardage, warp ends, loom waste, take-up, draw-in, and total yarn once your sett and picks-per-inch are already chosen.
Use a separate sett-planning tool when you still need to choose ends per inch, a reed starting point, or a sleying suggestion from WPI and weave structure. This page is the next step after that choice is already made.
| Feature | Weaving Calculator | Sett Calculator |
|---|---|---|
| Input | Sett (EPI), width, length | Yarn WPI, weave structure |
| Output | Warp/weft yardage | EPI, reed, sleying plan |
| Stage | Project planning | Yarn/structure selection |
They change how much yarn you need and how large the finished cloth will be. If you skip them, you will usually underestimate warp length and overestimate finished size.
| Factor | Plain Weave | Twill | Lace/Open |
|---|---|---|---|
| Take-up | 10–15% | 8–12% | 5–8% |
| Draw-in | 8–10% | 5–8% | 5–7% |
| Loom waste | 24–36 in | 24–36 in | 24–36 in |
Measure WPI (wraps per inch) of your handspun yarn to determine sett, then add 15–20% extra yardage because handspun varies in thickness and you may need more for consistent beat.
