Floor to Floor Height
Floor to Ceiling Height
Loft Horizontal and Vertical Clearance
This is the distance measured from the floor, where your ladders will rest, to the floor of the room above, usually your loft/attic. This measurement is usually required for 'Sliding', 'Concertina' and 'Telescopic' style loft ladders as they require that the ladders be fixed to the floor using a (supplied) bracket.
Your Floor to Floor Height (mm)*
This is the distance measured from the floor, where your ladders will rest, to the ceiling of the same room. This measurement is usually required if the ladders are of the 'Folding' style, or come with an integrated frame and hatch.
This is a measure of the distance in your loft space from the hinge end of your loft hatch horizontally and vertically to the nearest obstruction. This may be the eaves of the roof, a boiler or other structural obstruction that you will not be able to move.
Loft Opening Dimensions
This is the maximum size of the 'hole' that could be made in your loft floor to accommodate your loft ladders, this may be bigger than the size of your existing loft opening if you have one. Consideration must be given to the position of joists and other obstructions such as cabling that put a natural limit on how big the opening can be made.
Landing Space and Swing Clearance
Landing space is the distance from the hinge of the hatch to the resting place of the feet on the floor once the ladders are fully extended. The distance is measured horizontally along the floor.
Swing clearance is the 'arc' through which folding ladders will move as they are retracted into the loft. You need to measure the distance from the hinge end of your loft hatch to the nearest obstruction, usually a wall.
