What to enter
| Input | Meaning and units |
|---|---|
| Net fabric mass (kg) | Enter net fabric mass in kg; use the same basis as the other measurements. |
| Usable width (m) | Enter usable width in m; use the same basis as the other measurements. |
| Measured grammage (g/m²) | Enter measured grammage in g/m²; use the same basis as the other measurements. |
Understanding your result
Length is inferred from net mass, not measured directly.
Common mistakes
- Gross roll mass overstates length.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.

What fabric length corresponds to net roll mass and grammage?
Calculate fabric roll length from net mass from the stated quantities. Length is inferred from net mass, not measured directly.
Common uses
- What fabric length corresponds to net roll mass and grammage
How it works
area=1000*mass/gsm; length=area/width
Worked example
Enter Net fabric mass: 30 kg; Usable width: 1.5 m; Measured grammage: 200 g/m². Results: Estimated length: 100 m; Estimated area: 150 m².
