About Construction Maths

Construction Maths was built on a simple premise: complex spatial engineering and material estimation shouldn't slow down your time on the job site.

We provide a comprehensive suite of digital calculation engines tailored specifically for contractors, structural engineers, architects, and dedicated DIY builders who demand exactness.

Uncompromising Accuracy

Every calculator is strictly coded according to universal building codes and structural engineering formulas to guarantee precise real-world outputs.

Built for the Job Site

Our interfaces are deliberately designed to be clean, fast, and highly responsive so you can crunch numbers easily from a smartphone while wearing gloves.

100% Free & Open

We strongly believe that access to critical planning mathematics shouldn't be hidden behind expensive paywalls or frustrating subscriptions.

From Spreadsheets to Software

What started years ago as a private collection of convoluted Excel spreadsheets used to estimate concrete pours, stair stringers, and roof pitches has evolved into Construction Maths.

We realized that tradespeople were wasting hours re-calculating the same geometry and volume formulas over and over. Furthermore, minor mathematical errors were leading to major material shortages or expensive over-ordering.

Today, our platform digitizes those complex formulas into intuitive tools. Whether you are framing a complex hip roof, calculating the exact yardage for a curved retaining wall, or determining load-bearing spans, our goal is to give you the exact numbers you need in seconds.
