Shares the Silverado EV platform and body dimensions. These figures are inherited from the mechanically identical sibling truck rather than published separately for this model. Off-road trims run wider and taller than the ranges above — measure your own truck before you rely on any of it.
Will a Sierra EV fit in your garage?
Checked against the four common garage setups, using the longest and tallest version of this truck — so a pass here is a pass for every configuration.
Single garage, 8×7 ft door
Fits — but tightOpening 96×84", bay 240" deep.
It fits, but only just: about 7 inches spare at the longest configuration. That is not enough room to walk past the tailgate.
Mirrors clear the opening by only about 0 inches a side. Most owners still fold them out of habit.
- Depth spare: 7"
- Headroom: 5.3"
- Mirror clearance: 0"
Single garage, 9×7 ft door
Fits — but tightOpening 108×84", bay 240" deep.
It fits, but only just: about 7 inches spare at the longest configuration. That is not enough room to walk past the tailgate.
- Depth spare: 7"
- Headroom: 5.3"
- Mirror clearance: 12"
Double garage, 16×7 ft door
Fits — but tightOpening 192×84", bay 240" deep.
It fits, but only just: about 7 inches spare at the longest configuration. That is not enough room to walk past the tailgate.
- Depth spare: 7"
- Headroom: 5.3"
- Mirror clearance: 96"
9×8 ft door, 24 ft deep
Fits comfortablyOpening 108×96", bay 288" deep.
Clears on length, width and height with room to work around it.
- Depth spare: 55"
- Headroom: 17.3"
- Mirror clearance: 12"
"Mirror clearance" is the total, both sides combined — halve it for the gap at each mirror. A negative number means the mirrors have to be folded.
The mirrors add 14.4 inches
This is the number people forget. The Sierra EV body is 81.6 inches wide, which sounds manageable against a 96 inch door — until the mirrors take it to 96 inches. Folded, it comes back to 84 inches.
| Measured across | Width | Through an 8 ft (96") door | Through a 9 ft (108") door |
|---|---|---|---|
| Body only | 81.6" | 14.4" spare | 26.4" spare |
| Mirrors folded | 84" | 12" spare | 24" spare |
| Mirrors extended | 96" | 0" spare | 12" spare |

Sierra EV size — frequently asked
How long is a GMC Sierra EV?
233.1 inches overall. Wheelbase runs 145.7 inches.
How wide is a GMC Sierra EV?
81.6 inches across the body, 96 inches with the mirrors extended and 84 inches with them folded. The mirrors add 14.4 inches, and they — not the body — are what has to clear your garage door.
Will a GMC Sierra EV fit in a standard garage?
Yes, in 1 of the 4 standard setups checked on this page, and tightly in 3 more. The table above shows which, and what fails where it does not.
How tall is a GMC Sierra EV?
78 to 78.7 inches, depending on drivetrain and suspension. A standard 7 ft garage door gives 84 inches of opening, so the stock truck clears — but a roof rack, light bar or lift kit eats that margin quickly.
What is the Sierra EV bed width between the wheel wells?
50 inches. That is the number that decides whether sheet goods lie flat on the bed floor: a 48 inch sheet of plywood needs more than 48 inches of clearance, so anything under that has to ride on top of the wheel wells instead.
