High Clearance Door Heights — What's Available

Our range covers four height bands:

2200mm Standard Suits most passenger vehicles. Not suitable for anything on this page.

2500mm High Clearance — The sweet spot for most caravan, boat, and 4WD applications. Clears a standard caravan with the aircon dome, most boats on trailers, and roof-racked vehicles with room to spare. If you're unsure whether you need high clearance, measure your vehicle at its tallest point and add 200mm minimum — if that exceeds 2200mm, this is your height.

2800mm Shed & Workshop For larger boats, high-roof commercial vans, and taller farm vehicles. Also popular for shed conversions where maximum usable interior height is a priority.

3100mm Large Shed Maximum domestic clearance Suits motorhomes, large machinery, and agricultural equipment. If you're building specifically to house a large vessel or vehicle, size up rather than down — you'll thank yourself when loading and manoeuvring in a tight space.

Boat Shed Doors — Special Considerations

Boat storage has a few specific requirements worth thinking through beyond just height.

Width matters as much as height

A boat on a trailer is often wider than a standard car and worth measuring carefully before you order. Our roller doors go up to 5400mm wide, custom-made to your exact opening. Width is rarely a limiting factor, but measure the boat at its widest point, including the trailer, before you order.

Corrosion resistance

Boats mean moisture. If your boat shed is near the coast, you're dealing with salt air on top of the usual humidity. Specify a Windlocked door for coastal sites regardless of whether your location is technically in a wind-affected zone — the heavier-duty guides and additional fixings also offer better corrosion resistance and longer service life in marine environments.

Clearance for masts and aerials

If you're storing a vessel with a fixed antenna, VHF aerial, or outriggers that can't be folded, measure with everything in place. Trailers also vary significantly in height — a boat that sits at 2400mm on one trailer might sit at 2600mm on another. Measure your actual rig, not a generic spec sheet.

How to Measure for a High Clearance Garage Door

Same process as any door, but height is the critical dimension here.

1. Measure your vehicle or vessel at its absolute tallest point — roof racks loaded, aircon dome up, aerial extended. Whatever state it'll be in when you drive it through.

2. Add a minimum of 200mm clearance — 300mm is better. You want margin for an uneven driveway approach, a slightly loaded trailer sitting differently, or just not having to hold your breath every time.

3. That total is your minimum door height — round up to the next available height band (2500mm, 2800mm, or 3100mm).

4. Measure your headroom — the space between the top of the opening and the ceiling or roof structure. A roller door needs approximately 200–300mm of headroom to coil. If you're tight on headroom, let us know — a low headroom kit may be required.

Wind Rating for High Clearance Doors

Taller doors present a larger surface area to the wind, which means wind loading is worth thinking about more carefully than on a standard door. If your site is coastal, elevated, or in a known high-wind corridor:

• Windlocked — recommended for coastal and exposed sites. Deep-track guide engagement prevents the curtain blowing out under load.

• Windstrong — required in cyclonic zones (C2/C3). Available in high clearance heights up to 5400mm wide.

If you're building a boat shed or caravan shed in coastal Queensland, WA, or the NT, don't default to standard. The upgrade cost is modest, and the consequences of a door failing in a storm with an expensive vessel behind it are not.

Automation

A tall garage door is a heavier garage door. Manual operation is perfectly fine, but if you're opening and closing it multiple times a day — or if the spring tension is on the higher end due to door size — an automatic opener makes daily use significantly easier. All our high clearance doors are compatible with automation, and battery backup options are available to keep things moving during a power outage.

If you're storing anything taller than a standard passenger car, don't try to make a standard door work. Size the door to the vehicle, not the other way around — and if you're building a new shed, always design for the largest thing you're likely to store, not just what you have today. Upgrading a shed door later is straightforward. Raising a shed roof is not.
