TIE-DOWN COUNT CALCULATOR — THE FEDERAL MINIMUM
One short crate and one long beam of the same weight need different numbers of straps. Enter length and weight for the federal minimum, and see which of the two rules is driving your count.
Calculate DOT-Required Tie-Downs for Any Commercial Load
One tie-down per 10 feet is the minimum formula — but weight, load type, and cargo shape all change the number. Get it right.
Enter cargo weight, length, and type. The calculator applies FMCSA 49 CFR §393.106 to return the minimum tie-down count and aggregate WLL required.
Under-secured commercial cargo is a federal violation. DOT inspectors will put you out of service on the spot for insufficient tie-down WLL.
