Amazon Stretches Maximum Box Length for FBA Shipments in the US
Sellers Can Now Send Larger Packages as New FBA Standards Take Effect from June 20
Amazon has announced a significant change for US sellers using Fulfillment by Amazon (FBA). Effective June 20, 2025, the maximum allowable box length for FBA shipments will increase from 25 inches to 36 inches. This update, revealed on Amazon’s Seller Central platform, is designed to provide more flexibility to sellers and bring packaging standards in line with broader industry norms.
Bigger Boxes, More Flexibility for Sellers
With the new FBA guidelines, sellers can now use longer cartons to ship their products to Amazon’s fulfillment centers. The updated maximum dimensions are:
* Length: 36 inches
* Width: 25 inches
* Height: 25 inches
* Weight: 50 lbs
These changes make it easier for sellers to consolidate shipments, reduce packaging costs, and meet customer demand for larger or bundled items.

Immediate Acceptance for Pre-Updated Shipments
Amazon has clarified that if sellers have already shipped packages that meet the new box length, those shipments will be accepted as standard size. There will be no additional fees or penalties, and the boxes will be processed without defects.
Why This Matters for Amazon Sellers
The increased box size can benefit sellers dealing in oversized or bulkier products, including those in home goods, electronics, sports equipment, and more. The adjustment also helps sellers streamline logistics, lower shipping expenses, and optimize inventory management.
Sellers are encouraged to review the updated FBA shipping and routing requirements on Seller Central to ensure compliance. Proper packaging and adherence to Amazon’s guidelines will help avoid delays or unexpected fees.
This update from Amazon Seller Central is a welcome move for FBA sellers looking for more packaging options and efficiency. By aligning with industry standards, Amazon continues to improve its FBA services and support the growth of its seller community. For detailed information, sellers should visit the official FBA shipping and routing requirements page.
