Compare Calculators

Whether you are comparing options or just need a quick check, the Pixel Calculator delivers an accurate result instantly, with every input editable so you can model your own scenario.

Engineering calculations — loads, stresses, concrete mixes and material quantities — underpin every safe structure. This Pixel Calculator performs one of these engineering computations using the standard formulas and factors used in Pakistani practice.

The calculation follows accepted engineering methodology for the specific problem, with the safety factors and material properties that civil and structural engineers in Pakistan apply in design.

While this tool gives reliable numbers for budgeting and preliminary design, final structural design must always be verified by a qualified engineer — the safety of a building depends on design work that no calculator replaces.

Use it for the day-to-day numbers: steel weights, concrete volumes, load estimates and material quantities that let you check a design or a quote quickly.

Come back to the Pixel Calculator whenever your numbers change; because everything runs live in your browser, you can re-run it as many times as you need at no cost.

If you have ever wanted a fast, reliable Roof Pitch Calculator that works on your phone without sign-ups or ads getting in the way, this is it — the figures update the moment you type.
