As of June 20, 2025, the maximum box length for FBA fulfilled items has increased from 25 to 36 inches.  This change gives sellers with larger products more flexibility to sell via the Fulfilled by Amazon (FBA) program!

What are the Old Maximum Box Dimensions for FBA Orders?

Before, the largest box you could send to Amazon had to stick to the dimensions below. Going over these limits often resulted in compliance issues, additional fees, or sometimes even shipment rejections.

  • Length: 25 inches
  • Width: 25 inches
  • Height: 25 inches
  • Weight: 50 lbs.

What are the New Maximum Box Dimensions for FBA Orders?

Now, sellers can use longer boxes without worrying about non-compliance. The updated FBA product dimensions are as follows:

  • Length: 36 inches
  • Width: 25 inches
  • Height: 25 inches
  • Weight: 50 lbs.
