Stairs & Ramps

Rise and run, stringers, angles, baluster spacing and ramp gradients.

• Baluster Spacing Calculator How many balusters a railing run needs and the exact centre spacing, so the gap never exceeds the limit and the end gaps match.
• Ramp Slope Calculator Ramp length for a rise at a target gradient, the slope as a ratio, percentage and angle, and the landings an accessible ramp needs.
• Stair Calculator — Rise, Run and Stringer Number of steps, riser height, going, stair angle and stringer length from the total rise, checked against the riser and going limits you enter.
