Range

Range is a measurement used to determine how far an autoattack or ability can reach. It shares the scale with movement speed, so one point translates to one game distance unit traveled. Note that autoattack range is measured differently to ability range. Given a source unit's hitbox and a target unit's hitbox, range is calculated as follows: autoattack range from edge to edge; targeted skill range from center to center; skillshot range from edge to edge; and the range of self-centered area of effects are from the edge of the source (the larger champions don't benefit less from auras than smaller champions). The difference is approximately 100 (i.e. 550 autoattack range is roughly 650 casting range)

Each champion begins the game with a particular base autoattack range. This can vary from 125 to 175 for melee units and 425 to 650 for ranged units. The highest base autoattack range for champions is held by. At level 18, the highest autoattack range is 703 held by surpassing  at level 13 with 658 autoattack range. This is because of.
