AnswerHow do you measure for a new radiator?
Measure the pipe-centre distance (the gap between the two valve tails), plus the available height and width on the wall — match these to the radiator's valve centres so it fits your existing pipes.

Getting the valve centres right avoids re-routing pipework, which is what turns a simple swap into a bigger job.
