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.

A single elevation of an independent-style scaffold, sized from standard bay and lift spacing into a rough bill of quantities for the supplier conversation.
The counts assume two rows of standards and standard spacings, so they are a materials guide rather than a design - the page says so plainly, and TG20 or a bespoke design check is still the scaffolder's job. Lengthen the elevation to 24 m and the bay count, standards and couplers all step up together. Open the browser edition to try it with your own figures.
Read the guide: How to work out scaffold quantities from an elevation - bays, lifts, tubes, boards, couplers and ties, worked through.
No - use it straight from your browser, on a phone, tablet or PC, with no sign-up. It works offline once it has loaded, and you can add it to your home screen or desktop like an app. There is also a Windows desktop version in the Microsoft Store if you prefer an installed app.
No sign-in and no account. Scaffolding Quantity Calculator keeps what you enter on your PC and works from the moment it's installed. You can register your copy for update notices if you want to.
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.
