Whether you're a professional or a DIY home builder, this app helps you plan safe, comfortable stairs in any configuration. Multiple Stair Types: Supports straight stairs, L-shaped (quarter-turn), U-shaped (half-turn), double L-shaped (two 90° turns), spiral staircases, and curved/circular stairs. Input your basic dimensions and the app handles the rest. Accurate Calculations: Instantly compute step count, step height (rise per step), tread depth, total run, stair angle, and more. Uses standard formulas to ensure your design meets building safety guidelines for rise and run. Material Estimates: Get a rundown of the materials needed for your staircase. See the number of stringers, treads, risers (if used), and even approximate concrete or lumber volume – so you can plan your project and budget effectively. Visual Feedback: View a scale stair diagram with key measurements labeled. Adjust inputs and see updates in real time. Color-coded indicators warn if any dimension is outside safe ranges, helping you refine your design. Flexible Units & Settings: Work in imperial or metric (ft/in or mm/cm) and switch anytime. Customize details like adding/removing risers, tread nosing overhang, stringer size, slab thickness, balustrade height, and more to match your project. Save & Share Results: Save calculations and compare different designs. Generate a summary report or diagram to share with clients or team members via email or text.
