Last reviewed 27 August 2026 · Based on current GOV.UK towing guidance and practical caravan-matching experience.
The figures you need
- Car kerb weight or mass in service
- Maximum braked-trailer weight
- Maximum permitted nose weight
- Caravan MTPLM
- Gross vehicle weight and gross train weight for final checks
What the calculator compares
The Tow Car Matcher compares the caravan MTPLM with the maximum braked-trailer weight you enter. It also calculates an 85% guide from the car’s kerb weight and identifies stock that falls within the figures supplied.
The maximum braked-trailer figure and the 85% guide answer different questions. One is a vehicle manufacturer limit; the other is practical matching guidance.
Why exact vehicle details matter
Cars sharing the same model name can have different weights and towing capacities. Engine, gearbox, driven wheels, trim, optional equipment and model year can change the result. Confirm all figures against your exact vehicle rather than relying on another car’s specification.
Treat the result as a shortlist
A calculator cannot account for every loading, stability, condition or driver factor. Use the result to narrow your choice, then verify the complete combination before purchase or towing.
Official sources and further checks
Rules and vehicle limits can change. Before towing, check GOV.UK towing-with-a-car guidance, GOV.UK towing weight and width limits and the documentation supplied by your vehicle, towbar and caravan manufacturers.
