Wondering if everything will actually fit in the truck you rented? This calculator compares your total item volume against the truck's rated cargo capacity.
Fill Percentage = (Total Item Volume / Truck Capacity) x 100
Example
800 cubic ft of items, 1,000 cubic ft truck capacity:
Fill % = (800/1000) x 100 = 80.0% - Items should fit
Why Real-World Trucks Rarely Hit 100%
This is a raw volume comparison assuming near-perfect packing efficiency - in practice, irregular furniture shapes, mattresses, and unusable gaps around bulky items mean most real moves top out around 75-85% of a truck's rated cubic capacity, even when "everything fits."
Leave a Buffer, Especially Near the Limit
If your calculated fill percentage lands close to 90-100%, strongly consider renting the next truck size up - discovering a truck is too small mid-load, after furniture is already disassembled and boxes are already at the curb, is a stressful and avoidable situation.
