MEASURING FOR A STAIRCASE

This is a GUIDE how to measure for a DOLLE staircase. We have stairs in all sizes suitable for many specifications. In the following we go through what you need to measure for a staircase.


New staircase - what is your need?

To find the right stair you need to decide whether the staircase should be space saving and how much. The more space saving a staircase becomes, the less comfort the stairs will typically have. In addition, you need to decide what course the stairs should have – straight flight, quarter turn (L-shape) or half turn (U-shape).

Straight flight stairs can be very space saving and at the same time keep a good comfort by having paddle treads / reversible steps. The quarter- and half turn stairs can also give a good space saving solution and at the same time keep a good going and comfort when walking the staircase. If you want a very space saving staircase, the going may be less than 18 cm, but there are stairs with paddle treads/reversible steps. Which, due to the design of the treads nevertheless gets a comfortable going over 18 cm. Be aware that the going (foot room) also have an impact on how much space the stair will take up in the room, this measurement is called total going length.

The going of a stair is the foot room you have on the tread surface when you go down the stair. As shown in the drawing, it is from the leading edge of the tread to the leading edge of the tread below.

If the going is above 18 cm it provides good comfort, a main staircase typically has a foot room above 21 cm.

Be aware that the going (foot room) also have an impact on how much space the stair will take up in the room, this measurement is called total going length.


MEASUREMENT OF FLOOR-TO-FLOOR HEIGHT

Start by figuring out how high the staircase should be. Here you need to measure from (finished floor) ground floor to finished floor on 1st floor. As shown on the drawing.

If your floor height is 270 cm, you can use a staircase with 11, 12 and 13 treads. More treads provide a lower rise height of the staircase. If you want a comfortable staircase to climb, you should choose a rise height in the range of 18 - 21 cm, but if you want the stairs to take up less space in the room, you can choose a higher rise. At a high rise you will find that the staircase is steeper to climb.
Rise height you find like this:
Floor-to-floor height / Numbers of treads

The best comfort is achieved at a rise height between 18 - 21 cm.


MEASUREMENT OF STAIRWAY OPENING

If you already have an opening size, then measure the width and length of your opening size (incl. flashing). The width of your stair opening can determine which staircase may suit your project.

If you do not have an stair opening jet, then you are free to pick the staircase you want and make opening size according to the dimensions. Under each staircase on our website you can find the Dimensions under "Downloads" pick the PDF "Dimensions". In the PDF you will find the opening size (lenght and width) for the staircase you want.

In this e.g. we have a quarter turn stair with 14 treads.

The black arrows and numbers show the dimensions of the stairs, and the red arrows and numbers show the size of the stairwell.

It is recommended that the opening width is at least 7 cm wider than the stairs including railings when the stair is mounted with railings on one side. If railings are to be installed on both sides of the stairs, the opening must be at least 10 cm wider than the staircase including railings. For spiral staircase the opening size must also be 10 cm wider than the diameter of the staircase.


MEASUREMENT OF DECK THICKNESS

Take the measurement from ground floor ceiling to finished floor on first floor, like on the drawing.

Please see the mounting instruction.


CONSIDER SLANTED CEILING

Slanted ceilings can affect the headroom of the stairs and the end of the horizontal railing on next level floor.

Tip: Draw the stairs on the floor with paint tape and then draw the steps on the wall and make a check measure for the headroom.
