Mechanically identical to the Silverado 1500; body dimensions match within half an inch. 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 1500 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 tight

Opening 96×84", bay 240" deep.

Depends on your configuration. The shortest version fits a 240 inch bay with 29 inches to spare; the longest is 242 inches long and would not close the door.

Mirrors clear the opening by only about 0 inches a side. Most owners still fold them out of habit.

  • Depth spare: 29" shortest, -2" longest
  • Headroom: 5.3"
  • Mirror clearance: 0"

Single garage, 9×7 ft door

Fits — but tight

Opening 108×84", bay 240" deep.

Depends on your configuration. The shortest version fits a 240 inch bay with 29 inches to spare; the longest is 242 inches long and would not close the door.

  • Depth spare: 29" shortest, -2" longest
  • Headroom: 5.3"
  • Mirror clearance: 12"

Double garage, 16×7 ft door

Fits — but tight

Opening 192×84", bay 240" deep.

Depends on your configuration. The shortest version fits a 240 inch bay with 29 inches to spare; the longest is 242 inches long and would not close the door.

  • Depth spare: 29" shortest, -2" longest
  • Headroom: 5.3"
  • Mirror clearance: 96"

9×8 ft door, 24 ft deep

Fits comfortably

Opening 108×96", bay 288" deep.

Clears on length, width and height with room to work around it.

  • Depth spare: 77" shortest, 46" longest
  • 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 14.8 inches

This is the number people forget. The Sierra 1500 body is 81.2 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.

Sierra 1500 size — frequently asked

How long is a GMC Sierra 1500?

Between 210.9 and 241.7 inches, depending on cab and bed. That spread is the whole ball game for a garage: the short configuration and the long one are effectively different vehicles when it comes to parking. Wheelbase runs 126.5 to 157 inches.

How wide is a GMC Sierra 1500?

81.2 inches across the body, 96 inches with the mirrors extended and 84 inches with them folded. The mirrors add 14.8 inches, and they — not the body — are what has to clear your garage door.

Will a GMC Sierra 1500 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 1500?

75.5 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 1500 bed width between the wheel wells?

50.6 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.
