Enclosed Trailer Size Guide:
Matching Interior Dimensions to the Load
Enclosed trailers are measured by their interior floor dimensions, and selecting the right size requires knowing both the floor space and the interior height the load requires. A 5x8 provides 40 square feet of floor space with limited height clearance, suitable for compact loads, smaller apartment contents, or a focused tool setup. A 6x12 provides 72 square feet and covers the majority of one to two-bedroom moves and single-trade equipment configurations.
The 7x14 and 7x16 sizes provide enough floor space and interior height for full household moves, large appliances, tall shelving units, and multi-trade equipment arrangements. For Killeen renters unsure whether a 6x12 or 7x14 is the right fit, describing the specific large items in the load to Big Rentals during the rental conversation is the fastest way to confirm the right size without guessing.
