A. This depends on the size of the tent you have bought. A standard sized roof tent will measure approx. 125cm in width and this is sufficient for two adults to sleep comfortably. Larger pop-up or clamshell rooftop tents will measure approximately 145cm – this is almost the width of a king-size double bed and two adults and a child can fit in this size. Bigger sleeping spaces are provided by fold-out rooftop tents, where room for 5 people can be provided. It is possible to connect a waterproof annex to the side of certain fold out tents, these annexes provide extra living space where items can be stored, or extra camp beds can be installed for sleeping.
