Concrete Step Calculator

Pouring a porch step, entryway steps, or a short flight from a patio to a yard? Enter the rise and run of each step, how many steps there are, and the width — the calculator adds them up as a stack of solid steps and gives you volume, weight, and bag counts.

FAQ

How is stair volume estimated?
As a stack of solid rectangular steps, which forms a triangular profile in total. This is a solid-fill estimate — it doesn't subtract space if the stairs are built over an existing slope or fill.
What's a typical rise and run?
Most residential exterior steps use a 7 in. rise and 11 in. run, but check local code — comfortable, safe stairs usually keep 2×rise + run close to 24–25 in.

Concrete steps FAQ

What's a comfortable rise and run for steps?
Most exterior residential steps use a 7 inch rise and 11 inch run. A common comfort rule keeps 2 × rise + run close to 24–25 inches — check your local building code for exact requirements.
Does this account for the space under the steps?
This calculates a solid stack of steps. If your stairs will be built over compacted fill, gravel, or an existing slope rather than poured solid, your actual concrete volume will be lower.
