StairCalc - Stair Calculator

STAIR FRAMING, DECKING & FLOORING CARPENTRY CALCULATOR.
Stairs Calculator, Decking Estimator / Calculator, Setout, Concrete and other calculation!

StairCalc is designed for carpenters, contractors and builders who need accurate stair, decking & flooring calculations.

It is designed to save you the time and effort required for these building calculations - but it is not intended to teach you how to build stairs or decking - you already know how.

No need to remember complex data entry steps in order to enter data - start entering in any field. Double tap on buttons for help and guides.

Simultaneously find solutions when restrictions on tread, step rise, incline and 2R+G are required or ignore All or any number of restrictions - maximum flexibility.
Calculate when overall Rise & Run are both variable or fix either one - uses Long press Option.

Accurate and reliable, it is an indispensable tool for the stair framing, decking & flooring construction pro.
Developed by carpenters and used by contractors and builders around the world.

Metric or US/Imperial (feet, inches - decimal or fractions).

Also includes a general calculator simplified for construction calculations including a tape which can be emailed.

STAIRCALC INCLUDES:-

STAIR FRAMING (currently for single stair runs):-
Set upper and lower limits for step rise, treads, incline values and the slope formula 2R+G (2R+TD in some areas) where required by codes - all or only some applied at the same time.

In addition to handling multiple restrictions simultaneously Staircalc also allows for situations where the overall stair rise is fixed or the stair run is fixed or both rise and run are fixed allowing maximum flexibility.

◆ Number and size of step risers,
◆ Number and size of treads, step inclines,
◆ Step incline,
◆ Stairwell opening,

DECKING & FLOORING SETOUT, MATERIAL ESTIMATING and COSTING:-
◆ Options for Insets, single or double bearers
◆ Set Spacing type to maximum, fixed or equal
◆ Set pricing for materials / labour to calculate cost and cost/area
◆ Print, email or message lists and even makes notes on first

TIMBER SETOUT:-
Calculate and print list of stout positions.
◆ Equally spaced, maximum spacing or fixed spacing options;
◆ Insets at start and end.
◆ Lists of set out positions;
◆ Print, email or message lists and even makes notes on first;

CONCRETE ESTIMATOR:-
◆ Concrete Calculator/Estimator for Slabs, footings, round and rectangular/square holes
◆ Calculate quantities for slabs, footings, round and rectangular/square holes.
◆ Estimates total volume and cost allowing for waste.

CONVERTER:-
◆ Convert Lengths, Area, Volume: Metric and US/Imperial.
◆ Work in Decimal units or Yds/Ft/In/Fraction format to Metric, decimal US.

EASY TO USE GENERAL CALCULATOR WITH TAPE:
◆Calculate (add, subtract etc) directly in feet / inches / fractions or decimals.
◆Common functions for quick calculation

INFOGUIDE:
Infoguide is part of a small building firm based in Western Australia. This app was created by a former Roof Framing Carpenter for our team of carpenters. We use it and believe it will be as helpful to other carpenters as it was for us.
