Measuring your Pitched Roof / Rafters
The simplest way to measure a pitched roof is to….
- Measure the length and the height (Eaves to Ridge) of the internal loft space.
- Then Multiply these figures together.
- If your home has two sloping roof sections, then multiply this by two.
Example – If the length is 8m, and height is 4.3m:
8m x 4.3m = 34.4m²
34.4m² x 2 = 68.8m²
Total m² = 68.8m²
Below is a list of insulation materials for pitched roof/ rafter level insulation applications:
Measuring your Loft Floor Joists
The most effective way to measure a loft floor is to take the length of the loft space, then multiply this by the width to calculate the area.
Example – The length of loft is 6.2m, and the width is 4m.
6.2m x 4m = 24.8m²

Measuring you Gable End
The simplest way to measure a Gable End is to…
- Measure the width along the loft floor.
- Then measure the height of the wall, from the loft floor to the ridge.
- Multiply these measurements together, and finally divide by two.
Example – Loft floor width is 3.5m, and height is 4m.
3.5m x 4m = 14m²
14m² divide by 2 = 7m²

Measuring your Rafter Centres
The most effective way to measure the centres of your rafters. Firstly measure the left side of one rafter, to the left side of the next rafter along and repeat this for how many rafters you have. Commonly rafter centres are between 400mm & 600mm. This method can also be used for measuring Stud Walls & Loft Joists.
