Start with measured net dimensions, then enter supplier coverage, spacing and waste allowances. A material estimate does not determine load capacity, safe construction details or compliance with local building requirements.
Limitations and common mistakes
- Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
