Venus would get a slight radius buff, too, if we applied that metric.

But Venus has a solid surface.

Yes, that's why I said buff. The radius as defined would increase, because surface pressure is 90 bar, so at 1 bar, you're pretty high in the atmosphere. I can see merit in such a definition because that is the level at which we wouldn't have to pressurize our space stations to be comfortable. (Really 1/3 bar is fine too.)

Ah, I see what you're saying, didn't know the surface pressure was so high! I suppose Titan would also get an atmosphere radius buff!
