How to Measure for a Straight Staircase

A straight staircase is generally the easiest type of staircase to measure for.

Floor-to-Floor Stair Span

1

Floor to floor

AKA ‘finished floor to finished floor height’ or ‘total rise’. This is the dimension measured from the top of the floor downstairs, to the top of the floor upstairs, it is important that this dimension is accurate.

2

Total floor space

AKA ‘total going’. This is the physical length that the staircase takes up as measured along the floor. If you do not know this size, don’t worry, we can calculate it for you.

Opening length

AKA ‘well length’. This is the length of the floor opening. If you have no yet cut out the floor opening then do not worry, we can work out this for you.

4

Opening width

This is the width of the opening, we would recommend that this should be;

  • Staircase without posts;15mm wider than the staircase
  • Staircase with posts; 100mm wider than the staircase, this is to allow for room for the fingers once the handrail is installed.
  • Also remember to account for plaster when working out the width of the opening.

    Floor to ceiling

    If you would like us to work out the headroom for you we will need this dimension. This is the dimension from the ground floor to the underside of the finished ceiling (usually plasterboard).

    Other Tips

    In old buildings, sometimes the floors are not level. Please call us for advice with this.
