How long is a three horse trailer?

  • Bumper Pull horse trailers: 16 ft to 19 ft long

How do I know how long my horse trailer is?

If you are not sure how long your three horse trailer is, there is a simple way to measure it. 

When measuring a horse trailer you must find the height of the trailer, the interior dimensions of the storage options, and the exterior dimensions. The dimensions of a horse trailer vary widely. The measurements allow you to properly plan your trip or to know precisely the details of the sale of a horse trailer. 

Here’s how you measure a horse trailer:

  1. To measure the height of a horse trailer, one trick is to put a ladder adjacent to the highest point on the trailer with the horse trailer unloaded and level. Use a tape measure to determine the height of the vehicle. Measure from the highest point on earth for the most accurate measurement.
  1. To measure the length of the horse trailer, measure from the front-most corner of the back to the length of the trailer, but don’t measure the tongue. Measure the width of the rear of the trailer, not including wheel wells, if the wheel arches protrude from the trailer.
  1. To measure the volume of the horse trailer, measure the height of the inside of the trailer from floor to ceiling, the length of the rear wall of the doors, and the width from side to side. Multiply the three measurements to get the cubic volume. 

For example, a trailer advertised as a 13-foot trailer indicates that the length of the rear wall of the doors is 13 feet. The cubic feet measurement indicates the cargo space of the trailer, for example, a trailer with interior measurements of 10 by 6 by 4 meters has a volume of 240 cubic meters.

The law states that, for example, any means of transporting animals must be previously disinfected by an authorized center. The other alternative that horse owners have is to take a course to obtain the official certification that allows disinfecting, disinsecting and derating these vehicles.

At a private level, we can carry out the transfer of these animals, but with certain limitations. These are:

  • Only within the same autonomous community.
  • Both the animal and the vehicle must be legally in the name of the interested party. In addition, the driver must be the owner of both.
  • The displacement must not be for profit.
  • In some states, it is not possible to transport more than two horses, so pay attention to that!

How to choose a horse trailer?
