Note on taking measurements
All dimensions must be based on external measurements of the building or structure involved and not internal measurements.
- These calculators are based on standard building shapes.
- They should be used with care if the building you are measuring involves a combination of these forms or differs in a significant way from those in the calculator.
- If in doubt seek advice from a qualified person or your Local Planning Authority.
