About Stair and Angle Calculator
Stair and Angle Calculator gives tradespeople and DIYers six precise calculators in one clean, fast app. No clutter,
no subscriptions — just the numbers you need on site.
STAIRS
Enter total height, total run, and maximum step height. The app works out the number of steps, exact riser height, and
going, accounting for optional top and bottom landings.
ROOF
Calculate rafter length, ridge height, and roof area. Work by pitch angle or by rise — enter your total span and the
app does the rest. Add roof depth to get surface area for materials.
TRIANGLE
Solve any right-angle triangle. Enter two of the three sides (A, B, or hypotenuse C) and get the missing side, both
angles, and area instantly.
AREA
Switch between rectangle and circle modes. Enter length and width for area, or add height to get volume — useful for
concrete, soil, or fill calculations. Circle mode gives area and circumference from a radius.
CIRCLE
Go deeper with circle geometry. Enter a radius and optional arc angle to calculate arc length, chord length, and
sector area — useful for curved walls, arches, and landscaping.
ROOM
Plan paint, tiles, and flooring for any room. Enter length, width, and height, then specify the number of doors and
windows (or a total opening area) to get net wall area automatically deducted.
UNITS
All calculators support mm, cm, m, and ft. Switch units at any time using the ruler button — inputs convert instantly.
Simple, reliable, and built for real work.
