➖ Strip Footing Calculator for Concrete & Masonry
Estimate concrete for continuous footings.
This free tool helps you turn project measurements into a practical planning estimate. Enter values in Vaelden’s interactive calculator, review the result, and confirm important assumptions against supplier data, measurements, codes or qualified advice before committing materials or money.

How to calculate strip footing
Method: Footing volume = total length × width × depth × contingency
- Measure continuous footing runs consistently.
- Use the designed trench width and depth, not a nominal shovel width.
- Account separately for pads, steps, piers and over-excavation.
Worked example
Using these planning inputs:
- Total footing length: 18
- Footing width: 0.45
- Footing depth: 0.3
- Waste: 10 %
Concrete required: 2673.00 L
Reality check: Footing size and founding depth are structural decisions affected by soil, loads, drainage and local requirements.
Before you calculate
Use consistent units and the best measured inputs available. Real materials, equipment, site conditions and tolerances can change the result. Vaelden shows planning estimates; regulated, structural, electrical, plumbing, pressure and other safety-critical work still requires appropriate local compliance and professional advice.
