Loft Height – For the loft height measure from the bottom of the floor joists to the highest point on the ridge.
Loft Size – For the loft size, measure from your left wall to your right wall (gable to gable), then measure from your front wall to back wall (wall plate to wall plate). For example, if your gable to gable is 7.2m and your wall plate to wall plate is 5.5m, multiply the two figures together and that gives you the square meterage of your loft at 39.6m2. If you are struggling to get these measurements from your loft an alternative is to measure the outside walls of your property.
