About this calculator
Check whether your kayaks and gear are within your vehicle's roof rack and crossbar weight limits before hitting the road.
Frequently Asked Questions
What happens if I exceed my roof rack's weight capacity?
Exceeding capacity can bend crossbars, damage your roof, or cause the load to shift or detach while driving, creating a serious safety hazard.
Does kayak weight include water absorption?
Yes, factor in extra weight if your kayak has absorbed water, especially for older or damaged hulls.
Where do I find my roof rack's static weight capacity?
Check your vehicle owner's manual or the roof rack manufacturer's specifications, as this differs from dynamic (driving) capacity.
