Caravan noseweight at a glance
- What it is
- The static downward force the loaded caravan's coupling head presses onto the car's towball, read on a noseweight gauge.
- The target band
- 5–7% of the caravan's actual laden weight (use MTPLM only as a fallback if the laden weight is unknown). Guidance for stability, not law.
- The hard cap
- The lowest of four limits: the towbar's plated S-value, the car's own noseweight limit, the caravan's drawbar limit and the caravan's hitch coupling.
- How to measure it
- A BS7961 noseweight gauge, or bathroom scales and a timber prop, taken at normal towball height on level ground with the jockey wheel taking the full hitch weight.
- What changes it
- Where you pack: heavy items forward of the caravan's axle raise it, behind the axle lower it. Pack heavy and low, close to the axle.
- Why it matters
- Too little and the car's rear lifts and the outfit can snake; too much and the front lightens and the rear axle and towbar are overloaded.
Here is the part that catches people out: you can change your noseweight without adding a single kilogram to the caravan. Move a heavy box from behind the axle to in front of it and the figure on the gauge climbs, even though the van weighs exactly the same. Noseweight is a question of balance, and this guide shows you how to measure it, dial it into the right band, and check it against the limit that actually caps it.
What is noseweight on a caravan?
Noseweight is the static downward force your loaded caravan's coupling head presses onto the car's towball — a measure of where the caravan's weight sits, not how much of it there is. You read it with a noseweight gauge, and it is the figure that decides whether the outfit sits level and tows steadily or noses up and starts to weave.
Picture the caravan as a see-saw balanced on its own single axle. Weight loaded in front of that axle tips the nose down and presses harder on the towball; weight loaded behind it lifts the nose and lightens the ball. The number you set is the result of that balance, which is why two identically loaded vans can show very different noseweights.
In the UK the term is noseweight. It is the same idea the Australians call tow ball mass and the Americans call tongue weight, though those terms never change what it is: the static download at the hitch, measured at the coupling head (NCC Caravan Towing Guide, February 2024; Caravan and Motorhome Club).
What should my caravan's noseweight be?
Aim for a noseweight in the region of 5–7% of the caravan's actual laden weight — its real loaded weight, not the maximum on the plate (NCC Caravan Towing Guide, February 2024). Where the laden weight is not known, the same band is applied to the MTPLM as a fallback proxy, but the laden figure is the proper basis.
This guide runs one illustrative outfit throughout. It is a composite, not a real registered car or caravan. The caravan has an MTPLM of 1,500 kg and an actual laden weight of 1,450 kg. Five to seven per cent of 1,450 kg gives a target band of 72.5–101.5 kg, with about 87 kg at the 6% midpoint. (Worked on the 1,500 kg MTPLM the fallback band would be 75–105 kg — close, but the laden figure is the one to use.)
The band exists for stability. A noseweight inside it keeps the outfit settled at speed; it is guidance, not a legal figure, and it is only half the answer. The other half is the hard cap below.
What is the maximum noseweight I'm allowed?
Your maximum is the lowest of four physical limits, and the 5–7% band does not override it. Four separate components each carry a noseweight rating, and the smallest of them is your ceiling (NCC Caravan Towing Guide, February 2024):
| Limit | What it caps | On the worked outfit |
|---|---|---|
| Towbar S-value | The towbar and ball assembly, plated by the towbar maker | 85 kg |
| Car noseweight limit | The car's own published maximum, in the handbook | 100 kg |
| Caravan hitch coupling | The coupling head fitted to the caravan's drawbar | 100 kg |
| Caravan drawbar | The A-frame the coupling sits on | 100 kg |
The S-value is the maximum vertical static load the towbar can support through the towball. The towbar manufacturer publishes it and stamps it on a plate fixed to the towbar, and it typically falls between 50 and 150 kg (NCC Caravan Towing Guide, February 2024). It is set by type approval — ECE R55, formerly 94/20/EC — and it must not be exceeded.
On the worked outfit the four limits are 85 kg (towbar), 100 kg (car handbook), 100 kg (caravan hitch coupling) and 100 kg (caravan drawbar). The lowest is the towbar, so the cap is 85 kg.
This is where the band and the cap pull apart. The 5–7% range on the 1,450 kg laden van would let you run up to about 101.5 kg, yet the towbar plate stops you at 85 kg. So the lowest physical limit, not the percentage, sets your number. That 85 kg works out at 5.9% of the laden van, which still sits inside the band — the towbar just pins it to the lower half rather than letting the percentage choose.
How do I measure caravan noseweight?
Measure it at the coupling, at normal towball height, on level ground, with the jockey wheel carrying the full weight of the hitch (NCC Caravan Towing Guide, February 2024; Caravan and Motorhome Club; Bailey). Two methods give you the figure:
- A noseweight gauge. A proprietary gauge sits under the coupling and reads the download directly. Look for one made to the BS7961 standard.
- Bathroom scales and a timber prop. Cut a length of timber so the coupling rests at its normal towball height, stand it on the scales, lower the hitch onto it, and read the weight. Cheap and effective if the height is right.
Height is the detail that trips people up. Measure with the coupling too high or too low and the reading is wrong, because the caravan is no longer balanced where it will sit on the car. Park on level ground, get the coupling to towing height, and let the jockey wheel take the full hitch weight before you read anything.
How do I change my noseweight?
You change noseweight by moving weight relative to the caravan's axle, not by adding or removing it. This is the "where you pack, not how much" lesson, and it is the most useful thing to know about loading a van.
Pack heavy items low and close to the caravan's axle as your starting point — it keeps the van stable and the noseweight predictable. From there you trim the figure:
- To raise noseweight, nudge heavy items forward of the axle, towards the front of the van.
- To lower noseweight, move heavy items behind the axle, towards the rear.
A full awning locker at the front and a heavy item in the front bed box both push the nose down; the same gear stowed in the rear washroom lifts it. Small shifts move the gauge a surprising amount, which is exactly why the see-saw, balanced on the axle, is the picture to keep in mind (NCC Caravan Towing Guide, February 2024; Caravan and Motorhome Club; Bailey). The same placement that sets your noseweight also decides what each axle carries — our guide to loading a caravan and its axle weights works that through, single- and twin-axle.
Does noseweight count towards my car's payload?
Yes — the noseweight presses on the towball, so it counts towards the car's loaded weight and spends its payload before you have packed a bag. The car's payload is its maximum gross weight minus its kerbweight. On the worked outfit that is 2,450 kg MAM minus 1,900 kg kerb, a payload of 550 kg. An 85 kg noseweight spends about 15% of that 550 kg straight away, leaving roughly 465 kg for passengers, fuel and luggage.
It gets heavier on the rear axle than the raw figure suggests, because the ball sits on a hitch behind the axle and works as a lever. The illustration below is loadmate's own worked derivation, not a regulator's figure:
Additional rear-axle load = noseweight × ((rear overhang + 150 mm hitch) ÷ wheelbase)
On the worked car — 1,100 mm rear overhang, 2,700 mm wheelbase, and the 150 mm the hitch hangs behind the rear overhang:
85 kg × ((1,100 + 150) ÷ 2,700) = 85 × 0.463 = +39 kg
So the rear axle carries the 85 kg ball plus about 39 kg from the lever — roughly 124 kg in total — while about 39 kg comes off the front axle, lightening the steering. Weigh the rear axle on its own, not just the whole car, and you will see it.
| Number | What it measures | What caps it |
|---|---|---|
| Payload | How much weight you may add (its maximum weight minus its empty weight) | The caravan's MTPLM, or the car's MAM |
| Noseweight | Where the weight sits — the download at the coupling | The lowest of the four physical limits above |
Payload is how much you may add; noseweight is where it ends up sitting. For the caravan side of payload — MTPLM, MiRO and how to work it out — see the pillar, MTPLM, MiRO, MAM and payload explained.
What happens if my noseweight is too high or too low?
Too little noseweight makes the outfit tail-heavy and prone to snaking; too much lifts the car's front, overloads the rear axle and risks the towbar limit. Higher noseweight generally means a more stable tow, particularly above 50 mph, which is why the band sits where it does rather than at zero (NCC Caravan Towing Guide, February 2024; CaSSOA).
- Too low. A tail-heavy van lifts the car's rear, takes weight off the driven wheels, and is far more likely to start weaving and then snaking at speed.
- Too high. The car's front lightens, so the steering goes vague and the headlights point skyward, while the rear axle and the towbar both take more than they should — and the towbar's S-value is the limit you reach first on the worked outfit.
The fix for either is the same: move weight relative to the axle and re-measure, rather than just adding or stripping gear.
Is the 5–7% noseweight figure the law?
No — the 5–7% band is stability guidance, not a legal limit, and noseweight is not separately plated in law the way MTPLM is. The enforceable hooks sit elsewhere, and getting noseweight wrong is dangerous because of what it does to those other limits.
Two things are enforced. The car's axle and gross weights are legal limits: exceeding the maximum permitted axle weight can mean a fine of up to £300 or a court summons, and DVSA can issue a roadside prohibition (gov.uk/guidance/driving-a-van; DVSA graduated fixed penalties). The towbar's type-approval S-value (ECE R55, formerly 94/20/EC) must not be exceeded. So the honest framing is this: noseweight isn't separately plated in law the way MTPLM is, but getting it wrong can put you over the car's rear-axle or gross weight, which are enforceable, and over the towbar's type-approval limit, which must not be exceeded.
For the overload penalty bands themselves — the £100, £200 and £300 graduated fixed penalties and the court-summons threshold — see the UK caravan weights pillar, which sets them out in full.
Check the noseweight against your real limits
A percentage feels like a tidy answer, but 6% of a laden van tells you nothing until you know whether that figure clears a particular towbar, coupling and car. The free Can I Tow It? check closes that gap. Tell it the noseweight you expect to set and the noseweight limit on your car and coupling, and it reports back whether the coupling fits and which of the limits is the tight one — vehicle, caravan, coupling, or the combined ceiling. The reading is a spec-based estimate built from the numbers you give it, with no account required and nothing to pay. Keeping your own caravan and car on file, so you can re-check them whenever you re-pack or swap the towball, is the loadmate Pro step.
loadmate provides decision support for towing safety, not legal weight certification. For legal weight evidence, use a certified weighbridge. Towing remains the operator's responsibility — see /safety-disclaimer. To check a coupling against a car's limit now, the free check lives at /tow-check.

Frequently asked questions
- What is noseweight on a caravan?
Noseweight is the static downward force the loaded caravan's coupling head presses onto the car's towball, read with a noseweight gauge. It measures where the caravan's weight sits — its balance over its own axle — not how much weight it carries.
- What should my caravan's noseweight be?
Aim for a noseweight in the region of 5–7% of the caravan's actual laden weight; use the MTPLM only as a fallback if the laden weight is unknown. On a 1,450 kg laden van that is about 72.5–101.5 kg. It is guidance for stability, not a legal figure.
- What is the maximum noseweight I'm allowed?
The maximum is the lowest of four physical limits: the towbar's plated S-value, the car's own noseweight limit, the caravan's drawbar limit and the caravan's hitch coupling. On the worked outfit the towbar's 85 kg is the lowest, so it sets the cap even though the 5–7% band would allow more.
- How do I measure caravan noseweight?
Use a noseweight gauge made to the BS7961 standard, or bathroom scales and a length of timber cut so the coupling sits at its normal towball height. Measure on level ground with the jockey wheel taking the full hitch weight, at the coupling itself — the wrong height gives a wrong reading.
- Does noseweight count towards my car's payload?
Yes. The noseweight presses on the towball, so it counts towards the car's loaded weight and spends its payload. On the worked car an 85 kg noseweight uses about 15% of a 550 kg payload, and the lever effect loads the rear axle by more than the raw figure while lifting weight off the front.
- Why does where I pack change my noseweight?
Because the caravan balances on its own axle like a see-saw. Loading heavy items forward of the axle tips the nose down and raises noseweight; loading them behind the axle lifts the nose and lowers it. You change the figure by moving weight, not by adding or removing it.
- Is the 5–7% noseweight figure the law?
No. The 5–7% band is stability guidance, and noseweight is not separately plated in law the way MTPLM is. The enforceable limits are the car's axle and gross weights and the towbar's type-approval S-value, and getting noseweight wrong can put you over those.
- What happens if my noseweight is too high or too low?
Too little makes the outfit tail-heavy and prone to snaking, especially above 50 mph, because it lifts the car's rear. Too much lightens the car's front, making the steering vague, and overloads the rear axle and the towbar. Adjust by moving weight relative to the caravan's axle, then re-measure.
- What does the S-value on my towbar mean?
The S-value is the maximum vertical static load the towbar can support through the towball, published by the towbar manufacturer and shown on a plate on the towbar. It typically falls between 50 and 150 kg and is set by type approval, so it must not be exceeded — and it is often the lowest of the four noseweight limits.
