[Vocabulary] Diameter size or diameter length or just diameter?

[nyggus]

Hello,

Imagine I'm to measure diameter of some round objects on a photo. Having these measures (say, 1.1, 1.5 and 1.7 cm), should I talk about diameter or diameter size or diameter length? A sentence might be, "Comparing diameter sizes of these objects, we noticed..."

Thanks,
nyggus
