Stair landing layout calculator

Riser height is total floor-to-floor rise divided by the entered total riser count. Each flight has one fewer individual tread than risers because its landing or upper floor provides the final surface. For 2800 mm rise and two flights of eight risers, risers are 175 mm, each flight has seven 250 mm goings and the intermediate landing is 1400 mm above the lower floor.

The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.

• Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
• Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
• When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Plan geometry only. Landing dimensions are entered, not selected from a building code. A return layout requires room for two flight widths; any remaining width is the central gap. Floor openings, headroom, nosings, finish thickness, guardrails, structural members and local accessibility requirements are not checked. PDF/SVG output is a schematic, not a full-size cutting template.
