Stair Calculator for Stair Stringers

Stair stringers are used as the support structure for stairs and staircases this stair calculator can tell you how many steps you require.

If you’re building a new house that sits above ground level or has 2 stories or if you’re planning on raising your existing house, you’ll need stair stringers for your staircases.

At LevelMaster, our stair stringers are in stock and also hot dipped galvanized after fabrication. Hence the stringers have internal and external corrosion protection.

To work out how many stairs you’ll need and how much it will cost, use our stair calculator table below, or give us a call on 1300 538 356.

 

Stair stringer treads: rise and going

Our stair stringers range from 1-17 treads (steps) and are made for standard ‘rise’ and ‘going’.

The rise is the vertical measurement taken from one step level to the next. Standard rise is 175mm.

The going is the horizontal measurement taken from the front of one step to the next. Standard going is 250mm.

The picture bellow shows the rise and going of a staircase.

How many treads (steps) will I need?

To calculate the number of treads (steps) you will need to, simply measure the vertical distance from the landing to the ground, and then divide this figure by 175 (the height between each step). You’ll also then need to round the figure to the nearest whole number and deduct 1 for the top landing (as it’s already a step). ((VERTICAL HEIGHT/175)-1)

Example:

A height of 1425 divided by 175 = 8.14 (round to 8) minus 1 = 7 treads required

 

Stair calculator table

Using the table below you can calculate the cost of your stair stringers based on how many treads you will need. If you don’t know how many treads you’ll need, refer to the example formula above.

Our stair stringers are sold as pairs (you need 2 stringers per staircase). You can choose either ‘bolt down’ or ‘cast in’ stair stringers, depending on your needs; the cost of each type is the same. If your treads are over 1000mm in length, an extra stringer will be required for support, this is stated in our engineering documents.
