Curtain Panels from Chosen Fullness Calculator
Curtain Panels from Chosen Fullness Calculator — change the supplied values to calculate curtain panels from chosen fullness.
Custom fullness and usable width supplied; no sewing, mounting or safety recommendation. Count tolerance at exact boundaries follows existing ceil_count.
Accepted inputs: Track width: 0.01 to 100 m; Chosen fabric fullness ratio: 1 to 4 number; Panel width: 0.01 to 100 m.
How the calculation works
n=ceil(track width×fullness/panel width)
Required flat fabric width divided by usable panel width gives fractional demand; round up to whole panels.
Worked example
With track width 2 m, chosen fabric fullness ratio 2 number, panel width 1.4 m, curtain panels from chosen fullness is 3 panels.
Assumptions and limits
Custom fullness and usable width supplied; no sewing, mounting or safety recommendation. Count tolerance at exact boundaries follows existing ceil_count.
