What dimensions do I need when planning my staircase?

In order to be able to select a suitable staircase, the following dimensions are particularly relevant:

  • Basic dimensions (A): The space available for your staircase is a decisive factor in determining which models are suitable. It is best to measure the length and width of the space available for the stairs on the floor of the room. Using the floor plan of the room can help here.
  • Dimensions of the ceiling opening (B): The diameter of spiral staircases, the width of space-saving staircases and the dimensions of the hatch box for loft staircases must be chosen to match the ceiling opening. Therefore, be sure to measure the length and width of your ceiling opening before purchasing your staircase. For system staircases, please note that the ceiling opening must be 10 cm larger than the dimensions of the staircase. For example, a spiral staircase with a diameter of 140 cm requires a ceiling opening with a length and width of 150 cm.
  • Room height: The room height is also an important parameter for planning a staircase. Here a distinction must be made between two dimensions:
    • Storey height (C): The floor height is measured from the top edge of the floor to the top edge of the ceiling or gallery. It is the determining factor for the choice of system staircases.
    • Clear room height (D): For loft ladders, on the other hand, the clear room height is the essential parameter. It is measured from the upper edge of the floor to the lower edge of the ceiling.
  • Ceiling thickness (E): The ceiling thickness is also particularly relevant for the installation of attic stairs. To find it out, simply measure from the lower edge of the ceiling to the upper edge of the ceiling.
  • Fold-out space (F): It should be noted that attic stairs usually require a certain amount of space to fold out. This area exceeding the basic dimension is called the fold-out space.
