Today’s Scale Measurements

Load readings stay temporary and clear when you switch trailers.

How are you measuring this load?

Use total trailer weight plus tongue and axle-group measurements.

Using Trailer Scale Measurements

Total and axle-group measurements control the calculation.

Measured tongue weight

Used with either measurement method.

Total loaded trailer weight

Measured axle-group weight

Scale load carried by the trailer axle(s).

About this trailer weight calculator

Use this free trailer weight calculator to evaluate tongue weight, axle loads, individual tire loads and available capacity against the ratings saved for your trailer. It is designed for common utility, equipment, flatbed, enclosed and gooseneck trailers using single-axle or tandem-axle configurations.

Measure the current loadEnter total trailer weight, tongue weight and axle-group weight, or use complete individual wheel-scale readings when available.

Check limiting componentsCompare the heaviest measured axle and tire with axle, tire, GAWR, GVWR and tongue or hitch ratings.

Plan with reserveReview tongue-weight targets and recommended ratings that leave about 15% unused capacity for planning.
