Spell range and duration limits

[BigGus]

Do the range and duration of spells top out at any point? I had the impression it was caster level 20, but now I come to look I can't find anything about it anywhere. Did I just imagine that, or have I not looked in the right place?

Do the range and duration of spells top out at any point?

If it isn't say directly - no.

You are probably thinking about the damage caps on spells (Page 36 of the 3.5 DMG).

Range and Duration and any other non-damage level based parts of a spell don't have a cap unless the spell says so.
