Range

Range is a measurement used to determine how far a champion's basic attacks can reach. It shares the scale with movement speed, so one point translates to one game distance unit traveled. Each champion begins the game with a particular base range. Note that range does not relate to abilities, which have their own individual range. The difference is approximately 100 (e.g. 550 attack range is roughly 650 casting range)

Base ranges can vary from 125 ~ 175 for melee units and 425 ~ 650 for ranged units.

The highest base range for a champion is held by at 650.

For comparison the turret's range is 800 making the only champion who can outrange a tower with his ultimate  activated.
