About Tongue Weight Scales

Tongue weight means the weight that the fully loaded trailer exerts on the hitch ball of the tow vehicle.

Did you know that tongue weight is typically 10 percent of your gross trailer weight? And it must not exceed 15 percent. For example, a 10,000-pound trailer should have a tongue weight between 1,000 and 1,500 pounds.

Adjustment of your trailer’s tongue weight is made by adding or removing cargo or redistributing your trailer’s load. It’s important to note that the tongue weight must not exceed your tow vehicle capacity, hitch, or any towing components.

It’s also important to know that too much weight could damage the trailer tongue, leading to a catastrophic failure on the highway. On the other hand, too little weight on the hitch can go into an uncontrollable fishtail at highway speeds.

So, how can you be sure if you’re loaded properly? The answer is to use a good trailer tongue weight scale, like the ones we list in this article.
