Increase Container Fill Rate: A Guide for Cost & Process

Container fill rate is a quiet driver of logistics cost. Using fewer containers for the same goods reduces freight, storage, and handling—while keeping safety and stack stability intact.

What is fill rate?

Simply: loaded cargo volume divided by usable container volume. If fill is 70%, the remaining 30% is paid empty space—often caused by inconsistent dimensions and unplanned stacking.

1) Manage volume and weight together

Loading is not only about volume. Containers have limits: max gross weight and structural constraints. Track center of gravity and layer weights.

2) Standardize dimensions

Inconsistent box/pallet sizes create compounding gaps. Standardize where possible or group similar items per layer.

3) Choose a stacking strategy

• Block stacking: high utilization, good stability.
• Column stacking: easier height control, safer for some goods.
• Cross stacking: often a “last layer” gap‑closing technique.

4) Treat voids as a design parameter

Voids can be unavoidable—but where they are matters. Wall‑side voids increase movement risk. Visual tools can show voids layer by layer.

5) Optimize the last layer

Many losses happen on the last layer. Reserve small/light items for it, and use complementary carton sets (same footprint, different heights) to close gaps.

6) Operational benefits

• Fewer containers / fewer shipments
• Faster loading (standard plan)
• Lower damage rate (void management)
• Lower carbon footprint

Practical workflow with LoadBlok

Enter items (dimensions, quantity, weight, stackability), view placement, and verify total volume and total weight. This speeds planning and team communication.

Summary

Increasing fill rate is not just “fitting more”—it’s optimizing cost, safety, and process efficiency together.
