Hide unreadable names

[Yukka]

Hello world

I want to talk about something that annoys me when I play. When people are too far from me (30 meters) their names above their heads become little and unreadable. So I would like to create an addon that hide people names that are too far from me to be readable. But I need to keep showed the names of people that are close enough to be readable. I would be thankful if one of you can help me with some code.

Here is a screenshot that shows the issue:

As you can see, the names of the players in the inn are undreadable because they are too far. But the closest ones are perfectly readable.
