Parking
Will the 2021 Tesla Model X or 2017 Tesla Model 3 fit in a standard parking space?
2021 Tesla Model X parking fit score
DriveSize compares the car's width and length with typical parking-space sizes by region.
Vehicle dimensions are rounded up and available side or length clearance is rounded down.
Side clearance is based on body width excluding mirrors where available; real spaces can vary because of mirrors, walls, pillars, kerbs, bay markings, and nearby cars.
For an average USA / Canada space: body side clearance is 37.5 cm per side (excluding mirrors), and length clearance is 22 cm at each end.
