Matching Your Trailers with the Right Ball Hitch Sizes

The back of a jeep with a ball hitch

We’ve all been there, standing in the aisle at a farm store or hardware store a little panicked because we can’t remember what size ball goes with which kind of trailer. There are so many ball hitch sizes to know - everything from a lawn cart to a huge tandem axle trailer. And you can’t get it wrong either. Being an eighth of an inch off on the size of the ball can be an issue of safety for yourself and others. 

The easiest way to know is to find the sizing on the tongue of the trailer. It’s usually stamped onto the metal. The size mentioned is the diameter of the ball. While 2” and 2 5/16th” are common sizes for the trailers we carry, it’s good to review. Here are the ball hitch sizes and corresponding trailer types:
