What is a Stair Tread Calculator?
A stair tread calculator helps determine optimal step dimensions for safe and comfortable stairs. It calculates tread depth using standard building formulas considering total vertical height (rise) and number of steps. Proper calculations ensure compliance with safety codes, prevent accidents, and provide ergonomic comfort. Essential for construction professionals and DIY enthusiasts, it eliminates guesswork in stair design.
