Contact SupportIt shows you which Amazon FBA size tier your product falls into based on its dimensions and weight. An interactive 3D visualization updates in real time as you adjust sliders, and it displays the corresponding fulfillment fees and storage costs.
Amazon categorizes products into size tiers (Small Standard, Large Standard, Small Oversize, Medium Oversize, Large Oversize, Special Oversize) based on weight and dimensions. Each tier has different fulfillment fees, so knowing your tier helps you estimate costs and optimize packaging.
The tool uses the latest published Amazon FBA fee schedule. However, Amazon updates fees periodically, so always verify current rates on Seller Central before making business decisions. The tool is designed for estimation and comparison purposes.
When your product dimensions are within a small margin of a size tier boundary, the tool alerts you and shows exactly how much you could save by reducing dimensions to fit into the smaller tier. Even small packaging changes can lead to significant fee savings.
No. All calculations and the 3D visualization run entirely in your browser. No product dimensions, weights, or fee data are sent to any server.
