Vehicle Size and Height Limits: What to Check Before You Book

If you drive a large vehicle — a van, a pick-up, an SUV with a roof box, or anything with a bicycle carrier fitted — the question that decides whether you can use a particular car park is usually not how long the vehicle is, but whether it fits inside the operator's published size and height criteria. Those criteria are set by the individual car park or parking product, so there is no single number that applies everywhere.

This article is a reference explainer. It uses the published parking criteria of one UK airport operator, London Gatwick Airport, as a worked example of how such limits are written and where a driver should look. It does not claim that Gatwick's figures apply to any other site. For any other car park, you must check that operator's own published criteria before booking.

Is there a height limit?

At a car park that uses an automated or robotic parking system, there can be a hard maximum vehicle height, because the machinery has to move and store the vehicle within a fixed envelope. London Gatwick Airport publishes a compatibility list for its Robotic Parking product, and that list states a maximum vehicle height of 2.3m.

The same published criteria also set out other dimensional and weight requirements that a vehicle must meet to use that product:

• Minimum ground clearance: 120mm
• Maximum weight: 2.6 tonnes
• Wheelbase: between 1,800mm and 3,300mm
• Maximum overhang: 1,200mm
• Wheel diameter: between 500mm and 790mm
• Maximum vehicle height: 2.3m

These figures come from the operator's own parking FAQ page, which also notes that the system is described as compatible with around 95% of vehicle models, and that drivers whose vehicle has unusual dimensions or features should check the compatibility requirements before booking.

Two things follow from this. First, a height limit is not a general rule that applies to every car park; it is a property of the specific product. Second, where a limit exists, it is usually published alongside other limits — clearance, weight, wheelbase, overhang and wheel diameter — and a vehicle can fail on any one of them even if it passes on height.

Where the bundle does not cover a point, this article says so. The evidence used here does not state whether height limits apply to other parking products at the same airport, nor what any other operator's limits are. For those, a reader must check the relevant operator's own parking page and terms.

What about a van?

A van is not automatically excluded, and it is not automatically included. What matters is whether the individual vehicle meets the published criteria for the product being booked.

The Gatwick criteria are explicit that some larger vehicles fall outside the supported range. The list of vehicles described as not suitable for Robotic Parking includes vehicles weighing more than 2.6 tonnes, and it names "some loaded utility vehicles and larger commercial vans" as examples within that weight class. The same list also covers extra-long vehicles such as pick-up trucks, vehicles towing trailers, and other vehicles with a wheelbase longer than 3.3m or an overhang greater than 1.2m.

So the practical question for a van driver is not "are vans allowed?" but "does my specific van, as loaded, meet each published figure?" A panel van that is under the weight limit, within the wheelbase range and under the height limit may be fine for that product; a larger commercial van, or one loaded close to or beyond the stated weight, may not be. The published criteria also flag that the weight figure applies to the vehicle as presented, which is why the wording refers to loaded utility vehicles rather than to a bare kerb weight.

Height is a separate trap for vans and for cars alike. The Gatwick list of unsuitable vehicles specifically includes "extra-tall vehicles, including those fitted with roof boxes, bicycle carriers, or similar accessories, and vehicles exceeding 2.3m in height." A vehicle that fits the car park when empty may not fit it once accessories are fitted, because the accessory adds to the overall height that has to pass under or into the structure.

If you are unsure whether your van is covered, the safe path is to read the car park's own compatibility or size criteria before you book, and to contact the operator if the published page does not answer your case. The bundle used for this article does not state a procedure for appealing or overriding a failed compatibility check, so that detail is not stated here and must be confirmed with the operator.

What if my car is too big?

If your vehicle does not meet the published criteria for the product you were considering, the outcome is that the product is not suitable for that vehicle — not that the limit is waived. The Gatwick page frames this as a compatibility check: drivers with unusual dimensions or features are told to check the compatibility requirements before booking, and the page lists categories of vehicle that are not suitable.

Those unsuitable categories, as published, are:

• Extra-long vehicles, such as pick-up trucks, vehicles towing trailers, or other vehicles with a wheelbase longer than 3.3m or overhang greater than 1.2m
• Extra-tall vehicles, including those fitted with roof boxes, bicycle carriers, or similar accessories, and vehicles exceeding 2.3m in height
• Vehicles with low ground clearance, including sports cars and other vehicles with less than 120mm ground clearance
• Vehicles with wheel diameters outside the supported range of 500mm to 790mm
• Vehicles weighing more than 2.6 tonnes, including some loaded utility vehicles and larger commercial vans

Notice that the list is written as categories, not as a single measurement. A car can be too big in one dimension and fine in all the others, and it will still be unsuitable for that product. A long-wheelbase van may fail on wheelbase; a low sports car may fail on ground clearance; a family car with a roof box may fail on height.

Because the criteria are tied to a specific parking product, the practical answer for a driver whose car is too big is to look for a different product or a different car park whose published criteria the vehicle does meet. The bundle does not state what alternative products exist, what they cost, or whether they have different limits — those details are not stated here and must be checked on the operator's own parking pages.

Before you book: what to check, and where

The limits that matter are the ones published by the car park you are actually booking. A sensible sequence is:

1. Identify the exact parking product you intend to book, not just the car park name. Different products at the same site can have different criteria.
2. Find that product's published compatibility or size criteria. For the Gatwick Robotic Parking example, this is on the operator's parking FAQ page.
3. Measure your vehicle as it will be presented — including roof boxes, bicycle carriers and any similar accessories — and compare each figure: height, ground clearance, weight, wheelbase, overhang and wheel diameter.
4. Check the operator's terms as well as the parking page, because the terms set out the conditions you agree to when you leave the vehicle.
5. If your vehicle is outside the published criteria, do not book that product on the assumption it will be accepted. Confirm with the operator first.

On the terms side, the Gatwick terms and conditions describe what you must do when you have parked at the reception area: lock the vehicle securely and leave the keys with the car park operator, leaving only the keys needed to move the vehicle; fully close all windows; put the handbrake on properly; use any steering lock, alarm or immobiliser you have; not leave any animal or person within the vehicle; and make sure any belongings left in the vehicle are in a locked boot and not on display. The same terms state that the operator cannot be held responsible for loss or damage to your vehicle or belongings if you fail to do these things. They also require, before you leave the vehicle and the keys, that the vehicle is properly secured, roadworthy, has a current MOT certificate and has valid tax cover for the length of its stay, and that you follow all direction signs and other instructions when in the reception area.

Those terms do not themselves set height or size limits — the size criteria sit on the parking product page. That split is worth remembering: the limits are a booking-compatibility matter, while the terms govern what you must do once you arrive.

What is not covered here

This article deliberately stays inside its evidence. It does not state a height limit for any car park other than the one product described, because the bundle does not contain one. It does not state prices, booking fees, cancellation rights or refund rules, because the bundle does not contain them. It does not state whether a vehicle that fails a compatibility check can be moved to another product at no cost, because the bundle does not say so.

Where you need a fact that is not in this article, the authoritative place to look is the operator's own pages: the parking FAQ or compatibility page for the specific product, and the operator's terms and conditions. For the worked example used here, those are the London Gatwick Airport parking pages at https://www.gatwickairport.com/Airport_Parking and the London Gatwick Airport terms and conditions at https://www.gatwickairport.com/terms-and-conditions.html. Both were checked on 2026-10-06 for the purposes of this article.

The general principle to carry away is simple: height and size limits are set per car park and per product, they are published by the operator, and they must be checked before booking. A number quoted for one car park tells you nothing about another.
