By looking at weight to work out your towing capacity, that’s how.
Many confusing figures, acronyms and formulas are bandied about when people talk cars and caravan towing capacity. Really though, you only need to know two key ones: the kerbweight of the car and the maximum mass of the caravan (called ‘maximum technically permissible laden mass’, or MTPLM).
How do I work out my car’s towing capacity?
If the mass of the caravan is 85% or less of the car’s kerbweight, the car will tow it with ease. If it’s between 85% and 100%, be careful – only experienced caravanners should use that car to tow such a heavy van. But if the caravan is heavier than the car, that cars must not be used as a towing vehicle. This calculation is known by experts as ‘outfit matching’.
Where do I find the important weight figures?
You can find the kerbweight of your car in the owner’s manual, sometimes on a plate on the door sill or sometimes on the V5 registration document (look for the figure ‘G: Mass In Service’).
The weight of the caravan is usually listed on a plate near the door frame, but the manufacturer should also be able to tell you.
Is there an easier way to work out towing capacity?
This is a simple rule of thumb: even simpler is to consult the car handbook and find out what the maximum towing capacity it’s rated to lug.
You’re looking for the ‘braked trailer’ figure: a popular towing car is the Skoda Octavia, which has a 1,600kg braked trailer capacity for the best-selling 2.0-litre TDI model. It’s more than able to tow a family-sized caravan, which usually weigh around 1,300kg.
What else do I need to know?
Other key figures to watch for are that the maximum width of the trailer does not exceed 2.55 metres, and the maximum length of the car and the trailer does not exceed 7 metres.
If you passed your driving test before 1997, you don’t need a special driving licence: you can tow even heavy caravans with similarly large and heavy SUVs. If you passed your test after 1 January 1997, you are restricted to a total towing mass of 3,500kg.
This won’t be an issue for normal-sized cars and caravans but will be if you’re using a large SUV to tow a heavy caravan: the Land Rover Discovery 4, a popular tow car, weighs 2,700kg alone.

What are the best cars for towing a caravan?
Not every car is capable of towing a caravan, especially smaller cars - and you can forget about your hatchback being up to the challenge.
If you're still unsure about what car to use or you know your car is not suitable then it is well worth researching what cars can best tow a caravan.
