For illustrative purposes, the diagram on the left shows how to calculate the square meterage of a room with various obstructions and/or recesses. Here, for example, we have the typical living room layout in a standard Victorian terraced house, with both a chimney breast and bay window to accommodate. Follow the simple steps below, referring to the diagram, to effectively calculate your area. All you need is a tape measure, and something on which to note your measurements.
* Always add 10% for cutting and fitting. In this example, then, the grand total is 12.44 + 10% (1.24) = 13.68m2
* Round up to the nearest square meter.
You would therefore require 14m2 worth of Original Floorboard, in the finish of your choice, for this room.
