Trailer Tongue Weight Calculator
Check actual or estimated hitch weight against the loaded trailer weight, not the empty brochure number.

Why tongue weight matters
Too little tongue weight can make a conventional trailer unstable and prone to sway. Too much can overload the tow vehicle payload, rear axle, tires or receiver. The correct target comes from the trailer and tow-vehicle manufacturers.
- Calculate from the trailer as actually loaded for travel.
- Include batteries, propane, water and cargo added after the published dry weight.
- A weight-distribution hitch can redistribute axle load but does not create extra payload or raise a rating.
Planning ranges
| Configuration | Common planning range | Example at 6,000 lb |
|---|---|---|
| Conventional travel trailer | 10-15% | 600-900 lb |
| Fifth wheel | 15-25% pin weight | 900-1,500 lb |
| Boat / utility trailer | Manufacturer-specific | Check data plate and manual |
Frequently asked questions
What is a safe tongue-weight percentage?
A conventional travel trailer is commonly planned at 10-15 percent of loaded trailer weight. Always follow the trailer and tow-vehicle instructions.
Is dry hitch weight accurate?
It is only a starting point. Batteries, propane, water and cargo placement can materially change the real loaded tongue weight.
Does a weight-distribution hitch reduce tongue weight?
It redistributes some load across axles but does not erase tongue weight or increase the vehicle ratings.
