How to Determine the Correct Trailer Hitch Ball/Coupler Size
To determine the proper size for the trailer hitch ball and/or coupler you should be using, you'll need to measure your existing equipment and understand the exact weight you'll need to tow. Use these instructions to take measurements and make sure you're choosing the right size every time.
Step 1 Determine how much weight you're going to be towing.  | Step 2 Take the measurement from the ground to the top inside edge of the receiver tube.  |
Step 3 Use a hand level on the trailer jack to ensure the trailer is level and will allow for an accurate height measurement.  | Step 4 Take the measurement from the ground to the bottom of the coupler.  |
Step 5
Take both measurements and subtract the receiver height from the coupler height. This will tell you what ball mount size you need.
How to Choose a Trailer Hitch
When you’re choosing a trailer hitch for your business, here are the things you should consider.
- What is the gross trailer weight (GTW) and tongue weight (TW) for your operation?
- Does the hitch class match the vehicle and trailer you use?
- Will you need to use adapters, extenders, or special components (especially in industrial setups)?
- Do you require an adjustable trailer hitch to account for varying load heights, different trailers, or seasonal changes?
- What towing safety equipment do you need alongside the hitch (for example, safety chains, hitch locks, coupler locks, lighting, and load-securement gear)?
- Do you have a plan for trailer hitch maintenance, such as inspecting mounting bolts, receiver tubes, welds, and the condition of trailer coupling devices?
Pintle Hitch vs. Ball Hitch
In many industrial or heavy-haul applications, you’ll face the choice between two major connection types: the pintle hitch and the ball hitch.
| Ball Hitch | Pintle Hitch | |
| Primary Use | Standard trailer towing | Heavy haul, industrial, and off-road towing |
| Connection Style | A hitch ball connects to a trailer coupler | A lunette ring connects to a pintle hook or pintle mount |
| Typical Load Range | Suited for lighter loads and everyday towing needs | Built for demanding, high-vibration, and heavy industrial loads |
| Operational Complexity | Simple, familiar setup for most fleets | More robust setup designed for harsh environments |
| Articulation & Movement | Limited articulation; best on paved or controlled surfaces | Greater articulation to handle uneven terrain and rugged jobsites |
| Common Uses | Businesses towing standard utility, cargo, or light equipment trailers | Construction, manufacturing, and equipment hauling fleets that need durability under tough conditions |
When you decide between the pintle hitch and ball hitch, think about your terrain, load variability, trailer design, and downtime costs.
Knowing Your Towing Capacity
Keep in mind that your towing capacity is only as high as the lowest capacity of any part of your towing setup. You may also want to limit your towing to under about 80% of maximum capacity to allow a margin for error. Need to know your towing capacity and find parts that match your needs?
