Range determines how long tears will travel before landing, and is represented by a bow and arrow. Effective range is determined by a combination of the Range stat, Shot Speed, and Shot Height.
This attribute's name is misleading, because Range actually determines the time that a shot stays in the air rather than the "distance" that it travels. The effective range is calculated based on said travel time, shot speed, and shot height. Range cannot be lowered below 7.0, but has no upper limit.
Range up pills increase range by 2.5, and range down pills decrease range by 2.
In co-op, Long Baby will occasionally briefly increase range, shot speed, and tear height. Dark Baby will occasionally briefly increase all stats, including shot speed. Dripping Baby will occasionally briefly grant Anemic, increasing range.
