Multi-Box vs Single-Box Decision Imagine a customer orders two products. Option A — One large box Combined package: 30 × 24 × 20 DIM ≈ 104 lb Option B — Two smaller boxes Box 1 DIM = 25 lb Box 2 DIM = 20 lb Total DIM basis = 45 lb But you can’t blindly assume “two boxes are cheaper.” The company must compare: 2 shipping labels + 2 handling costs 45 lb equivalent vs 104 lb equivalent A DIM calculator helps quantify this decision, balancing shipping labels, handling costs, and DIM weight exposure.
