Absolutely, eyeballing and a bit of judgement are more than adequate for this kind of thing. Of you can not bother at all and just deal with it if/when a problem manifests.
But there's a cohort of people who insist on real numbers and real measurements. so there's a tool made for that.

Displacement measures volume, no? The volume of a chain doesn't change as it elongates, does it? Are you pulling our legs?

Elongated discussion on the chain wear but the subject is sprocket wear, front and back.

The change is very small. But it isn't zero.
