What Are The Horse Trailer Sizes?

Horse trailers are an essential tool for horse owners who need to transport their horses to shows, competitions, vet visits, or just for a change of scenery. Choosing the right horse trailer size is crucial for the safety and comfort of your horse, as well as the performance of your towing vehicle.

The majority of horse breeds are capable of comfortably fitting within a trailer measuring 6 feet in width (1.83 meters), 10 feet in length (3.05 meters), and 7.5 feet in height (2.29 meters). Ultimately, the size of the trailer suitable for a particular horse will be contingent upon the horse’s dimensions.

For a more in-depth understanding of horse trailer sizes, please keep reading. I will delve deeper into the topic of horse trailer dimensions and highlight important factors to consider when selecting the right horse trailer for you and your equine companion.

Factors to Consider When Choosing A Horse Trailer Size

When choosing a horse trailer size, there are several important factors to consider to ensure the safety and comfort of your horses, as well as the performance of your towing vehicle.

Horse size and number of horses: 

The size of your horse(s) and the number you plan to transport will play a significant role in determining the appropriate trailer size. Larger horses will require more space and headroom, while multiple horses will need enough room to stand comfortably and move around without feeling cramped.

Towing vehicle capacity: 

Your towing vehicle’s weight capacity and towing capacity will limit the size of the horse trailer you can safely tow. It’s essential to check your vehicle’s specifications and choose a trailer that falls within those limits.

Comfort and safety of the horses:

 Your horse’s safety and comfort should be a top priority when selecting a trailer size. The trailer should provide adequate ventilation, lighting, and padding, as well as enough room for your horse(s) to stand and move around comfortably.

Maneuverability and ease of towing: 

Larger trailers may be more challenging to maneuver and park, especially in tight spaces. Choosing a smaller trailer may be a better option if you plan to drive on narrow or winding roads or have limited towing experience.

Budget and storage considerations: 

Horse trailers come in a wide range of prices and sizes, and your budget will play a significant role in determining the size and features you can afford. Additionally, it’s essential to consider where you will store your trailer when not in use, as larger trailers may require more space.

Horse Trailer Sizes

It goes without saying that there isn’t a universal horse trailer size that accommodates all horses. The ideal trailer size for your horse will be determined by the amount of space it requires for movement and comfort. If a horse feels confined and restricted in its trailer, it can lead to increased stress levels.

The most common horse trailer size, which can usually accommodate a variety of horse breeds, is 6 feet wide by 10 feet long by 7.5 feet tall (1.83 meters x 3.05 meters x 2.29 meters), providing a total interior space of 450 cubic feet (12.78 cubic meters) for the horse to maneuver comfortably.

Ultimately, the dimensions of horse trailers may vary among different manufacturers. To give you an idea of the range of options available, I’ve included a list of horse trailer sizes offered by two popular companies, Equispirit and Exiss.

How to Measure Your Horse for a Trailer

Choosing the right horse trailer size starts with measuring your horse properly. Here is a step-by-step guide on how to measure your horse for a trailer:

  1. Measure the horse’s height: Use a measuring tape to measure the horse’s height from the ground to the highest point on its withers (the ridge between its shoulder blades).
  2. Measure the horse’s length: Measure your horse’s length from the point of their shoulder to the point of their buttock.
  3. Measure the horse’s width: Measure the horse’s width across the widest part of its body, typically its shoulders.
  4. Consider the horse’s weight: Make sure you know the horse’s weight to ensure the trailer can handle its weight.

How To Choose A Right Horse Trailer?

Choosing the right horse trailer for you and your equine companion can be a complex task. Here are some factors to consider when making your decision:

Size: As mentioned earlier, the size of the horse trailer will depend on the size of your horse and how much space it requires to move freely.

Type: There are several types of horse trailers, including bumper pull, gooseneck, and living quarter trailers. Consider your transportation needs and budget when selecting a type of trailer.

Safety: Make sure the horse trailer you choose has safety features, such as non-slip flooring, sturdy dividers, and adequate ventilation.

Convenience: Consider the ease of loading and unloading your horse, as well as the convenience of maintaining the trailer.

Budget: Horse trailers can range from a few thousand dollars to tens of thousands of dollars. Determine a budget and choose a trailer that fits both your needs and budget.

Brand reputation: Research the brand of the horse trailer and read reviews from previous customers.
