Frequently asked questions

Is a 24x24x24 box much bigger than a 20x20x20 box?

Yes - 24x24x24 holds about 8.0 cubic feet versus 4.6 for 20x20x20, roughly 73% more volume. That extra space costs more than the box price: dimensional weight and void fill both scale with cube, so size to the contents, not the bigger number.

When should I choose the 20x20x20 box instead?

Choose 20x20x20 when contents fit with under two inches of slack on each side. A tighter box cuts dimensional-weight charges, needs less void fill, and stacks more per pallet - the usual reasons oversized boxes quietly cost more per shipment.
