amazon warehouse size is a crucial consideration for sellers managing inventory through FBA. The dimensions and weight of your products determine how they’re categorized and stored in Amazon fulfillment centers. Understanding the various size tiers—such as standard-size, oversize, and special handling—can help you anticipate storage fees and optimize your packaging. Incorrect size classifications can lead to unexpected costs, especially during peak seasons. Sellers aiming to scale should study Amazon’s storage policies in detail and adjust their prep and shipping strategies accordingly. Efficient use of warehouse space not only impacts storage fees but also affects how fast products can be shipped to customers, influencing customer satisfaction and your seller performance metrics.
