Weaving sett and reed planner
Compare target warp ends with a fixed reed denting arrangement.
A clear answer. Here’s how.
Warp ends = ceiling(target width × target ends per inch) plus supplied edge ends. Occupied dents round ends divided by ends-per-dent up, and reed width divides dents by dents-per-inch. Effective sett assumes uniform denting; a partial final dent and extra edges can change local density. Does not infer a suitable sett from yarn type.

Worked example
A fixed demonstration, separate from the values you enter above.
- Target warp width (in)
- 12
- Target ends per inch
- 20
- Extra edge ends
- 4
- Reed dents per inch
- 10
- Ends per dent
- 2
Example result
- Warp ends including extras
- 244
- Reed dents occupied
- 122
- Reed width occupied (in)
- 12.2
- Effective ends per inch
- 20
Ends = ceiling(width × target ends/inch) + extra ends. Dents use the supplied fixed ends-per-dent; partial final dents can alter edge sett.
