How to measure a radiator
You'll need to measure your existing radiator to find the perfect replacement. Take all measurements in millimetres.
- Measure the height of the radiator -
Measure from the lowest point of the radiator (including feet or brackets) to the highest. This is essential for fitting within the available wall space. - Measure the width of the radiator -
Measure across the radiator from one end to the other. If the radiator has end caps or valves attached, measure just the panel itself. - Measure the pipe centres -
This is the distance from the centre of the left pipe to the centre of the right pipe. It’s crucial if you’re replacing a radiator without altering the pipework. - Measure the wall projection -
Measure from the wall to the centre of the pipes. This helps determine how far the radiator will stick out from the wall.
Replacing a radiator is a task many capable DIYers can handle, especially when swapping like-for-like with no changes to the existing pipework. However, if the job involves moving pipes, it’s best to leave it to a qualified plumber.
