Worldwide scaffold quantity calculator
Estimate scaffold tube, board and coupler quantities from an elevation - a to-scale front elevation shows every bay, lift and cross-brace at a glance, alongside a full bill of quantities.
The Elevation tab's to-scale front elevation, the Materials tab's full bill of quantities, and the Guide tab's component glossary.
Elevation tab - a to-scale front elevation
Materials tab - the full bill of quantities
Guide tab - a scaffold component glossary
Standards, ledgers and alternating cross-bracing drawn to scale from your elevation length, height, bay and lift spacing - see the whole structure at a glance, not just a number.
Standards, ledgers, transoms, base plates, boards, right-angle and swivel couplers, wall ties, guardrails and toe boards - every component quantified from your elevation.
Set your own bay length and lift height - the app recalculates bays, lifts and every downstream quantity instantly as you adjust the elevation.
Choose how many lifts are boarded out as a working platform and how many boards wide - board counts scale to match, not just the full structure.
A built-in glossary of standard scaffold components - standards, ledgers, transoms, couplers, ties and more - for anyone new to reading a scaffold quantity list.
Copy a plain-text summary or export it as a standalone HTML file. Light/dark theme remembers your choice, and rotating sample elevations let you explore the app.

Scaffolding Quantity Calculator is a Windows desktop app, free to try from the Microsoft Store.
Yes - Scaffolding Quantity Calculator uses the same shared Metre2 account as Vector, Forma and every other Keystone app. Sign in once and it works everywhere.
No - it's an approximate quantities guide based on standard bay/lift spacing assumptions, not a scaffold design or a substitute for a TG20/bespoke design check. Always have scaffolding designed, erected and inspected by a competent, qualified scaffolder.
An independent-style tube-and-fitting scaffold with two rows of standards, connected by transoms and ledgers at each lift - the most common configuration for general access and refurbishment work.
