Stair Landing Calculator
Calculate the proper dimensions for stair landings based on building codes and safety standards. Determine landing size, placement, and compliance requirements for your staircase design.
Step 1: Stair Dimensions
Building Code Guidelines
Most building codes require a landing when stairs have more than 12 risers. The landing should be at least as wide as the stairway and at least 36 inches deep in the direction of travel.
Step 2: Landing Requirements
Safety Requirements
Landings provide a safe resting point and allow for direction changes in stairs. Proper landing dimensions prevent accidents and ensure accessibility for all users, including those with mobility aids.

Landing Calculation Formula
Minimum Landing Depth = Stair Width (or 36″, whichever is greater)
To calculate minimum landing depth: Use the stair width or 36 inches, whichever is larger. The landing width must equal or exceed the stair width. Total rise = Number of steps × Rise per step.
