Noseweight: What it means and why it matters
Noseweight is the downward force a caravan exerts on the towball when hitched up. UK guidance is to aim for around 5 to 7 percent of the caravan's actual laden weight, while staying inside the car and towbar limits, for stable towing.
Noseweight, sometimes called hitch weight or tongue weight, is the vertical load the caravan transfers down onto the towball. Too little noseweight makes the caravan want to sway from side to side, often called snaking. Too much noseweight overloads the car's rear axle, lifts weight off the front wheels, and reduces steering grip. The accepted target in the UK is roughly 5 to 7 percent of the caravan's actual laden weight, and you must never exceed the lower of the car's maximum noseweight or the towbar's rated noseweight. You adjust noseweight by repacking the caravan: heavy items low, close to the axle, with a slight bias toward the front.
Why this matters
Wrong noseweight is one of the most common causes of caravan instability on UK roads. A cheap noseweight gauge and 10 minutes of repacking can be the difference between calm towing and a snaking incident at motorway speed.
Common misunderstandings
- Noseweight is not the same as caravan payload. It is just the downward force on the towball
- The legal limit is the lower of your car's max noseweight, the towbar plate noseweight, and the coupling head rating, not just one of them
- A heavier caravan does not automatically mean more noseweight. It depends on how the caravan is loaded
Example
Worked example: a caravan loaded to 1,400kg with the target 6 percent noseweight needs about 84kg on the towball (1,400 x 0.06 = 84). If your car's plate shows a 75kg max noseweight, you must rebalance the load until the gauge reads 75kg or under, even though the caravan would tolerate more.

Frequently Asked Questions
Aim for around 5 to 7 percent of the caravan's actual laden weight, without exceeding your car's maximum noseweight or your towbar's rated noseweight, whichever is lower.
Use a noseweight gauge, available from around £15. Place it under the coupling head on level ground, with the gauge set to towball height, and read off the figure.
Too little weight on the towball lets the caravan move independently from the car, which encourages snaking and loss of stability, especially at motorway speeds or in crosswinds.
