Measuring

Room measurements for a sim racing wheel stand or cockpit

The fit check uses the length and width of the open floor, the chair depth for a wheel stand and the inside size of the storage space. The seven measurements below cover a room that is not a plain rectangle.

1. Free floor rectangle. The free rectangle is the floor area with nothing on it, clear of any bed edge, desk leg or radiator. Painter's tape on the corners marks it out.
2. Two heights. The space is measured along the floor and again about 60 cm up. A windowsill, shelf or desk edge can cut into the space above a clear floor.
3. Door swing. A door that opens into the area takes its arc out of the free space. The arc is measured from the hinge wall to the end of the door's swing. A door that stays shut during driving takes nothing.
4. One unit. The fit check takes centimetres or inches. Length and width in different units give a wrong result.
5. Chair depth for a wheel stand. Chair depth is measured from the front edge of the seat to the furthest point of the backrest, reclined as it is for driving.
6. Clearance. The manufacturer's footprint is the frame only. Room to get in and out is extra, and the fit check has a clearance field for it.
7. Storage space. A closet is measured inside the door frame with the door open. The height is the clear height under any shelf.
