Scaffolding Quantity Calculator

Work out scaffolding quantity instantly with clear inputs, formula shown and shareable results.

About Scaffolding Quantity Calculator

Scaffolding is hired by face area, perimeter times height, which is how quotations are compared. The physical component count follows from the grid: bays across the elevation, lifts up it, and two rows of standards, inner and outer, with one more standard than there are bays in each row.

Formulas

Face area

m² = perimeter x height

Grid

Bays = ceil(perimeter / bay length); lifts = ceil(height / lift height); standards = 2 x (bays + 1)

Worked example

With the default values below, Scaffolding Quantity Calculator returns Scaffold face area of 720.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Preliminary estimate only. Scaffold design, tie arrangement and loading class must be specified by a competent scaffold designer to the applicable standard.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Scaffolding Quantity figure worked out?

m² = perimeter x height. Scaffolding is hired by face area, perimeter times height, which is how quotations are compared.

Why is lift height typically 2 m?

It gives working headroom under the next platform while keeping the guardrail at the right height, and it matches standard ledger and brace lengths.

What values do I need to enter?

This calculator takes 4 inputs: Building perimeter, Scaffold height, Lift height, Bay length. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
