Scaffolding Calculator
Calculate scaffolding frames, planks, and braces needed for your project.
Enter building height and length to get a complete materials list.
Scaffolding Materials Needed
Scaffolding estimation is based on the building height and length, using standard scaffold frame dimensions.
Imperial (standard frame 5 ft wide x 6.5 ft tall):
Levels = ceiling(Building Height / 6.5 ft)
Bays = ceiling(Building Length / 7 ft)
Frames = (Bays + 1) x Levels x 2
Planks = Bays x Levels
Cross Braces = Bays x Levels x 2
Metric (standard frame 1.5 m wide x 2 m tall):
Levels = ceiling(Building Height / 2 m)
Bays = ceiling(Building Length / 2.1 m)
Frames = (Bays + 1) x Levels x 2
Planks = Bays x Levels
Cross Braces = Bays x Levels x 2
Key components:
- Frames — Vertical end frames at each bay connection
- Planks — Walking/working platform boards per bay per level
- Cross braces — Diagonal braces for stability (2 per bay per level)
- Base plates — One per frame leg at ground level
Safety notes:
- Always follow OSHA scaffold standards (29 CFR 1926.451)
- Maximum platform height without engineering: 125 ft (38 m)
- Guardrails required above 10 ft (3 m)
