Nearly a Quarter of Every Box Is Air. Why That’s the Single Easiest Profit Leak in Your Fulfillment Center.

Imagine this: a customer orders three t-shirts. The packer grabs a medium box, tosses it in, adds some paper, tapes it, and moves on. Seems fine… until you realize that almost a quarter of every parcel shipped today is empty space. That’s money literally flying away.

Why oversized boxes still win

Speed > Finesse: Packers are rewarded for throughput, not precision.

“Good enough” is invisible: One slightly big box rarely triggers a review.

Carrier penalties exist: Dimensional weight rules quietly punish extra space.

All together? That’s a huge, unnoticed profit leak.

Smart cartonization in 2026

Forget spreadsheets or guesswork. Smart cartonization:

• Picks the smallest safe box automatically

• Optimizes multi-item orders

• Factors in shipping rates and accessorials

• Shows packers exactly what to do, no brain overload

The result? Faster packing, lower shipping costs, less filler, and fewer damaged items.
