How it works
Fabric Roll Calculator
Find the number of rolls to order, the weight of each roll and the surplus you will receive.
Rolls come in whole numbers, so the requirement is divided by the average roll length and rounded up.
Formula
The formula, in full
- Rolls
- ⌈ Fabric required ÷ Roll length ⌉
- Roll weight
- Roll length × Width (m) × GSM ÷ 1000
Example
17,500 m in 100 m rolls
- 0117,500 ÷ 100 = 175 rolls
- 02Roll weight = 100 × 1.473 × 140 ÷ 1000 = 20.6 kg
