Long range is 40 meters, the longest range of all spells, and nearly matches the PC's own perception sight range. It is about 4 "tiles" in NWN2, viewable from the toolset or if you guess in game. Interior tiles are slightly smaller, so it is about 4.2 tiles or so inside.

40 meters in feet is around 131 feet.

3.5E notes

Long range in 3.5E is defined as:

Long: The spell reaches as far as 400 feet + 40 feet per caster level.

Because of NWN(2)'s CRPG sizes, that is the area's buildings and distances are not to any real life scale, this doesn't fit, and would be unbalancing (and also hard to get a PC that can see the required 400 feet default range). The maximum range at level 20 is a staggering 1200 feet (~370 meters)!
