Landing Size Calculator
Calculate the minimum landing length, width, and area for straight, L-shaped, and U-shaped stair landings.
How to Use the Landing Size Calculator
- Enter the stair width in millimetres.
- Select the landing type (straight, L-shaped, or U-shaped).
- Click Calculate to see minimum landing dimensions and area.
使用例
- •Designing code-compliant stair landings.
- •Planning space requirements for stairwell landings.
- •Calculating material quantities for landing construction.
- •Accessibility and evacuation route planning.
計算式
Minimum landing length ≥ stair width. L-shaped: length = 1.5 × width. U-shaped: length = width = 2 × stair width.
よくある質問
What is the minimum landing size?
The minimum landing depth and width must be at least equal to the stair width in most building codes.
Why are L-shaped landings larger?
L-shaped landings must accommodate the direction change, requiring 1.5× the stair width in the turn direction.
