How to crouch in Fortnite
The many mechanics in Fortnite can be bound to any key or button if you go into your settings and change it. But the specific bind used to crouch by default depends on whether you’re playing on PC or with a controller.
If you’re playing on PC, the default keybind for “crouch” is the left CTRL. If you’re playing on an Xbox or PlayStation and using the “Standard” configuration, crouch is bound to LB for Xbox and L1 for PlayStation.
