Utility trailer deck size
Enter the measurements above to calculate utility trailer deck size.
How the calculation works
V12 calculation: requiredDeckLength=itemLength+2×tieDownMargin; requiredDeckWidth=itemWidth+2×tieDownMargin; orientationA=requiredDeckLength≤deckLength AND requiredDeckWidth≤deckWidth; orientationB=requiredDeckLength≤deckWidth AND requiredDeckWidth≤deckLength; fitPass=orientationA OR orientationB. This is the implementation specification for this calculator.
Worked example
Example: Longest cargo length = 45.15 cm; Cargo width = 48.36 cm; Trailer deck length = 95.57 cm; Trailer deck width = 112.04 cm; Tie-down margin = 22.79 cm. Result: Fits; Orientation B = Pass; Orientation A = Pass; Required Deck Width = 93.94 cm.
