DimGeniusFlatbed Trailer Dimensions
Also called: flatbed trailer, flat deck
A flatbed is an open trailer with a single flat deck and no sides or roof. Freight is loaded from the sides or from above with a forklift or crane and secured with straps, chains, and tarps.
Flatbeds are the default open-deck trailer for building materials, lumber, steel, pipe, and machinery that is within legal height. Because the deck sits roughly five feet off the ground, legal freight height is lower than on drop-deck trailers.
Dimensions and capacity
| Size | Length | Width | Max freight height | Max weight |
|---|---|---|---|---|
| 48' Flatbed | 48' (576 in) | 8' 6" (102 in) | 8' 6" (102 in) | 48,000 lbs |
| 53' Flatbed | 53' (636 in) | 8' 6" (102 in) | 8' 6" (102 in) | 48,000 lbs |
- Legal freight width is 8' 6". Wider loads are over-dimensional and need permits.
- Max freight height reflects the typical 13' 6" overall height limit on a deck about 5' high.
- These are the planning values DimGenius uses. Actual equipment varies by carrier — confirm with yours before booking.
