Frequently Asked Questions
How do I calculate concrete needed for steps?
Measure the width, depth (tread), and height (rise) of each step. The calculator accounts for the cumulative volume of all steps in the staircase structure.
How accurate is this calculator?
This calculator uses industry-standard formulas and is accurate within 5%. Always order 5-10% extra concrete to account for waste and spillage.
What is the standard step size?
Standard outdoor steps are typically 36-48 inches wide, 11-14 inches deep (tread), and 6-8 inches high (rise).
Should I use bags or ready-mix concrete?
For small projects (less than 1 cubic yard), bagged concrete is convenient. For larger projects, ready-mix concrete delivered by truck is more cost-effective.
