Curtain fabric
Estimate drops and fabric length with fullness and pattern matching.
How this works
Round up widths for fullness; round each drop plus hems to a full vertical repeat.
Example
Using the example inputs, total fabric length is 7.5 m.
- Rod width
- 200 cm
- Fullness multiplier
- 2 ×
- Usable fabric width
- 140 cm
- Finished drop
- 220 cm
- Total top/bottom allowance
- 30 cm
- Vertical pattern repeat (0 for none)
- 0 cm
- Total fabric length
- 7.5 m
Scope and assumptions
Excludes lateral pattern matching and separate lining; use usable width after selvages.
