Trailer Tongue Weight Calculator
Calculate proper trailer tongue weight percentage
About this calculator
The Trailer Tongue Weight Calculator helps determine the proper tongue weight percentage for safe trailer towing. Tongue weight is the downward force exerted by the trailer's coupler onto the hitch ball, typically recommended to be 10-15% of the total trailer weight. Proper tongue weight distribution ensures stable towing, prevents trailer sway, maintains vehicle control, and reduces wear on towing equipment. Incorrect tongue weight can lead to dangerous driving conditions, poor braking performance, and potential accidents.
How to use
Enter your trailer's total gross weight in pounds or kilograms. Input the measured tongue weight using a tongue weight scale or bathroom scale. The calculator will instantly display the tongue weight percentage and indicate whether it falls within the recommended 10-15% range for safe towing.
Frequently asked questions
What is the ideal tongue weight percentage?
The recommended tongue weight is typically 10-15% of the total trailer weight for conventional trailers and travel trailers.
How do I measure tongue weight?
Use a tongue weight scale, bathroom scale with a board, or visit a truck scale to measure the downward pressure.
What happens if tongue weight is too low or high?
Low tongue weight causes trailer sway and instability. High tongue weight reduces steering control and overloads the rear axle.
