Movement speed is how fast a hero is travelling.
Base movement speed[edit | edit source]
The base movement speed when moving forwards is 5.5 meters per second, except for Tracer and Genji who move forwards at 6 meters per second. When moving directly backwards, the base speed is 90% of the forward speed (4.95 for most heroes; 5.4 for Tracer and Genji). When moving back diagonally, the base speed is of the forward speed (5.133 for most heroes; 5.6 for Tracer and Genji).
While crouching, the base movement speed is 3 meters per second for all heroes, regardless of direction.
If Wrecking Ball is in his roll mode, his base movement speed is 10 meters per second, regardless of direction.
Modifiers[edit | edit source]
There are three categories to speed modifiers: speed buffs, slow effects, and movement penalties. Each category stacks with themselves and are added together before being applied to the current base movement speed. However, self-inflicted movement penalties and enemy slow effects do not stack and the greater of the two overrides the other.
Suppose Reinhardt and Lúcio are on a team and Symmetra is on the other. Reinhardt walks forward in Lúcio's speed aura (+25% buff). His speed is of his base speed. Symmetra places down one turret (−20% slow). Reinhardt's speed is now of his base speed. Reinhardt uses his barrier (−30% penalty). His speed is now of his base speed because Barrier Field's movement penalty overrides the turret's slow. Symmetra places a second turret (−20% ⟶ −40% slow). Reinhardt's speed is now of his base speed, regardless of if he uses his barrier or not, because the two turrets' slow overrides Barrier Field's movement penalty. Symmetra places a third turret (−20% ⟶ −60% slow) and Lúcio amps up his speed song (+25% ⟶ +60% buff). Reinhardt's final movement speed is his base speed.
The only other case where one speed modifier overrides another is with D.Va's Boosters (+118% speed buff) and Fusion Cannons (−50% movement penalty): If D.Va is using Boosters, her Fusion Cannons' movement penalty no longer applies.
