Closed Height vs Garage Clearance for Rooftop Tents

What closed height means on a listing

Closed height is the height of the tent when it is folded and secured on the roof. On a hard shell, that is the height of the rigid case. On a soft shell, it is the height of the folded fabric bundle with its cover on. Listings state this number in inches or centimeters, and it is one of the first details to look for when you plan to park in a garage.

The closed height alone does not tell you whether the tent fits your garage. You need the height of your vehicle's roof from the ground, which your vehicle manual states. Add the tent's closed height to that roof height, and the total is the lowest clearance your vehicle needs when the tent is mounted.

The maker's instructions and the vehicle manual decide the exact numbers. The site compares tents on stated details, so it can show you which models list a lower closed height, but the final fit depends on your vehicle and your garage.

• Closed height is the folded height of the tent on the roof.
• Your vehicle manual gives the roof height from the ground.
• Add the two numbers to find the total height with the tent mounted.

Measuring the garage door opening

The garage door opening is the first limit. Measure the height of the door opening from the floor to the top of the opening, and the width from one side to the other. The door opening height is often lower than the interior ceiling height, so it is the number that matters when you drive in.

Use a tape measure and record the numbers in the same unit the tent listing uses, usually inches. If the door opening is lower than the total height of your vehicle with the tent, the tent will not pass through, even if the interior ceiling is higher.

Garage floors are not always level. A slight slope at the entrance can change the effective height by an inch or two. Leave a margin of a few inches between the total vehicle height and the door opening height to account for that slope and for any roof accessories like antennas or crossbars.

Measuring the garage interior

Once the door closes, the interior ceiling height is the next limit. Measure from the floor to the lowest point of the ceiling, including any beams, lights, or openers. A garage door opener or a hanging shelf can sit lower than the ceiling and block the tent.

The interior depth also matters. If the garage is short, the vehicle may need to stop before the tent reaches the back wall. Measure the depth from the door to the back wall, and compare it with the length of your vehicle plus the tent overhang, which the tent instructions state.

The interior height is usually higher than the door opening, so the door opening is the number that decides the fit. But if you plan to open the tent inside the garage, the interior height determines whether the tent can open fully. The maker's instructions state the open height, and that is a separate question from closed clearance.

Comparing the numbers

Write down three numbers: the tent's closed height from the listing, the vehicle's roof height from the manual, and the garage door opening height. Add the first two, then compare the total with the door opening height. If the total is lower, the tent fits through the door, assuming the width also works.

Leave a safety margin of at least two to three inches. The tent's closed height is a stated detail, but the actual height can vary with the cover, the mounting brackets, or a mattress that compresses differently. The vehicle manual's roof height is for a stock vehicle; any lift or larger tires change it.

If the numbers are close, consider a tent with a lower closed height. Hard shell tents often list a lower closed height than soft shell tents because the rigid case sits closer to the roof. The best hard shell rooftop tents guide compares those stated heights, and the best soft shell rooftop tents guide does the same for fabric models.

What the site cannot tell you

The site compares tents on stated details, so it can show you which models list a lower closed height. It cannot tell you whether a tent fits your specific vehicle or garage, because that depends on the vehicle's roof height, the mounting system, and the garage dimensions.

The maker's instructions and the vehicle manual decide the fit. A qualified installer can answer questions about mounting and roof height. For garage clearance, the only reliable method is to measure your own garage and compare it with the numbers from the maker and the manual.

Common mistakes when checking clearance

A common mistake is measuring only the door opening and ignoring the interior. The door may be tall enough, but a low beam or a garage door opener can hit the tent once the vehicle is inside. Measure the lowest point of the entire path, not just the entrance.

Another mistake is forgetting the vehicle's roof height. The tent's closed height is only the added height, not the total. Your vehicle manual states the roof height, and you add the tent's closed height to it.

A third mistake is assuming the tent's closed height is exact. The stated number is a detail from the listing, but the actual height can change with the cover, the mounting brackets, or how the tent is secured. Leave a margin, and if you are unsure, ask the maker or a qualified installer.

When to ask the maker

If the listing does not state the closed height, or if you need the open height for comparison, ask the maker directly. The maker's official pages list the tent's dimensions, and the instructions give mounting details. The best rooftop tent guide links to the makers' pages for each pick.

Ask about the closed height with the cover on, and whether the stated height includes the mounting brackets. Ask about the open height if you plan to open the tent inside the garage. The maker's customer service can answer those questions, and the vehicle manual covers the roof height.

What to pick for your situation

Questions

What is closed height on a rooftop tent?

Closed height is the height of the tent when it is folded and secured on the roof. Hard shell tents have a rigid case, while soft shell tents fold into a fabric bundle with a cover. The listing states this number, and you add it to your vehicle's roof height to find the total height.

How do I measure my garage for a rooftop tent?

Measure the garage door opening height from the floor to the top, the interior ceiling height at the lowest point, and the depth from the door to the back wall. Record the numbers in inches, and compare them with the tent's closed height plus your vehicle's roof height.

What if the garage door opening is lower than the interior ceiling?

The door opening is the limit. If the total vehicle height with the tent is higher than the door opening, the tent will not fit through, even if the interior ceiling is taller. Measure the door opening first.

Can I open the tent inside the garage?

The interior height determines that. The open height is stated by the maker, and it is usually much taller than the closed height. If the interior ceiling is lower than the open height, the tent cannot open fully inside. Check the maker's instructions for the open height.

What if the tent's closed height is not stated?

Ask the maker directly. The official pages list dimensions, and the instructions give mounting details. The site compares tents on stated details, so if a listing omits the closed height, you can still compare other specs and ask the maker for the missing number.
