For most trailer brands, a warmblood size trailer has an inside height of 7 ft. 6 in. Typically, warmblood trailers are straight load, as they are built to accommodate larger horses. While some slant load trailers can fit large horses, they tend to be built for smaller horses, as the slant makes it more difficult for horses over 16 hands to fit.  When searching for a warmblood trailer, make sure to check that the height, width, length, and stall size will be a comfortable fit for all your horses. Horses should have enough room in their stalls to stretch, move their necks, and adjust their legs for balance, but they should not have so much space that they slide or turn around when the trailer is in motion.
