But what if the product’s size cannot be reduced? This is the most important point. If your product is: TV = 40 × 25 × 5 inches Then you cannot make the TV smaller. However, you can check: Is an unnecessarily large box being used? If the TV is being shipped in a 44 × 30 × 10 box, but a 42 × 27 × 7 box is feasible while ensuring safe packaging, then the DIM weight can be reduced by using a smaller shipping box. FedEx specifically recommends right-sized packaging, the use of padded or poly mailers, and minimizing overpacking.
