What are the different sizes of horse trailers?

In addition to grooming, lodging and food, the horses must be transported from time to time, either locally or over a long distance. Knowing the right size horse trailer for your needs will ensure that your animals travel in comfort and arrive safely at their destination. 

Horse trailers come in incline or straight load designs, with or without options, and vary in height, width and weight.

  • Standard straight load: A standard straight-load trailer design is a side-by-side rear door entry trailer where the horseheads face the front of the trailer. The standard size comprises the smallest horse trailer, which typically has a stall width within approximately six feet. These trailers typically have a square roof, with a floor-to-ceiling stop height of seven feet and a total length of the trailer of 10 feet. 

The standard trailer for horse sizes is from 14 to 16 hands. The roof should be extended to 7 feet, 6 inches for horses up to 16-3 hands, and an additional two inches for horses in 16-3 to 17 hands. Horses measuring 16-3 to 17 hands should have an extra one foot in trailer length, too.

  • Extra Large Straight-Load: Additional large straight-haul trailers have post lengths of 11 feet. They are six feet wide, but the ceilings extend to a height of 7 feet, 8 inches. With large cargo trailers, they are straight axles with widths of 96 inches, which represents a heavier load for the larger horses, ranging from 16-3 17-2 hands tall.
  • Double Extra Large Direct Loading: Additional double straight-haul trailers have the same length of 11 feet as the oversized one, and the width is maintained at 6 feet 8 inches. Height is 7 feet, 8 inches. The shafts extend to 102 inches wide. The extra-large double model typically houses horses ranging from 18 to 19 hands.
  • Custom-built straight load: Custom-built horse trailers accommodate horses that are 19 hands and taller. Draft horses with weights approach 2,000 pounds that fall into this category. The trailer must be at least 8 feet tall, with a 12-foot stopping length in addition. The tires and axles must be upgraded to support the additional weight with the addition of additional floor supports and the brace.
  • Tilt-Load: Tilt-load trailers differ in design from straight-load trailers in that the horses are loaded from left to right on an incline within the stalls. Due to the diagonal stalls, the overall length of the trailer is still shorter, measuring only 8 to 8 1/2 feet below the centre line. 

However, the length of the diagonal will approach 10 to 11 feet. Tilt-load trailers, due to their smaller size, cannot accommodate horses more than 15-3 hands tall. The tilt-load trailer has additional trailer tags with less hauling weight for the tow vehicle and more manoeuvrability.
