Range

Range is a measurement used to determine how far an autoattack or ability can reach. Riot tends to describe that distance in a vague measurement of "units". It shares the scale of "units" 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 250 for melee units and 300 to 650 for ranged units. As of 7.13, the highest autoattack range is 750 held by with 25, surpassing the 669 range of level 18  at 16  (675). as the highest autoattack range at level 1 with 650, surpassed by at level 16 with 655 autoattack range.

Size Model Modifiers
Ranges calculated from the of a champion's hitbox will see an increase or decrease in reach based on the champion's current size. Note that a change in range due to the champion's size is only relative to the champion's center and is not an explicitly mentioned effect (i.e. the champion's attack range stat will not increase).

 * His maximum size is increased by his maximum health.

While the following items do not explicitly increase the champion's attack range, they do increase the champion's size - allowing them to reach targets further away from their current location:
