In this short video, Lara Guevara emphasizes that sellers should apply the dimensional (DIM) weight formula to every SKU, not just their best‑selling product. She explains that any item shipped in a box larger than necessary incurs the same overcharge, and slower‑moving SKUs can suffer even greater penalties because they are rarely re‑evaluated. By spending roughly five minutes per SKU to run the DIM weight calculation, sellers can pinpoint the true shipping‑cost gaps instead of guessing which products to prioritize for packaging optimization.

In yesterday's video, I only ran the dim weight formula on one box size, and I want to be really clear about something. Run it on more than just your bestseller. Any SKU shipping in a box bigger than it needs to be is getting hit with the same overcharge, and some of your slower movers might actually be worse than your bestseller because nobody's ever gone back to check the box. So 5 minutes per SKU and you'll know exactly where the real gap is instead of guessing which one to fix first.
