Rooftop tent sizing and fitting for the UK: 2 vs 4 person weights, dynamic vs static roof loads, crossbar spacing and which vehicles take which tents.
Almost every roof tent sold in the UK is a 2-berth. A closed footprint of roughly 140cm x 120cm suits most cars, vans and 4x4s, weighs 45-60kg and stays inside the dynamic roof load of a standard crossbar set. Two adults fit comfortably; two adults and a small child is tight but common. If it is your first roof tent, this is the size to buy.
A 4-person soft-shell typically weighs 70-90kg closed and needs a wider bar spread, so check the dynamic load in your vehicle handbook before buying — plenty of cars stop at 75kg including the bars. Extended-floor designs overhang the rear or the bonnet, which changes how the ladder sits. On smaller cars a 2-berth plus an awning is usually the better trip setup.
Under £1,000 you are buying a soft-shell with a fold-out floor, a poly-cotton canvas and a telescopic ladder. They pitch in a couple of minutes, sleep just as well and take Scottish rain fine if the seams are taped. What you give up is pack-down speed, aerodynamics and the 5-year warranties the premium hard-shells carry.
Hard-shells start around £1,800 and run past £3,500. Gas struts lift the lid in under a minute, the shell doubles as a rain cover so you pack away dry, and the low profile is far quieter at motorway speed. The trade-off is weight, price and a slightly narrower bed.
