Vehicle Dimensions and Towing Calculators
Safe towing requires understanding your vehicle's limits and getting the weight distribution right. UK law requires that your trailer does not exceed 85% of your car's kerbweight for drivers who passed their test after January 1997. Our towing calculators help you stay legal and safe.
The towing capacity calculator checks your vehicle's gross train weight against the combined weight of car, passengers, and loaded trailer. The nose weight calculator ensures your tow bar loading is within the recommended 5-7% of trailer weight, which is critical for stability at motorway speeds.
Beyond towing, our dimension calculators help with everyday practicalities. The turning circle calculator is useful when considering a new car for tight urban streets, while the parking space calculator checks whether your vehicle fits with enough room to open the doors. The boot volume calculator helps you compare load capacity between models.
