Frequently Asked Questions
What is the standard riser height for concrete stairs?
The standard riser height is between 7 and 7.75 inches. Building codes typically require risers to be no more than 7.75 inches and all risers in a flight must be uniform within 3/8 inch.
How do you calculate concrete for stairs?
Calculate the volume of each step as a cumulative block (each step sits on the full height of all steps below it), then sum all step volumes. Add platform volume if applicable, and include 10% for waste.
