Amazon Increases Maximum FBA Box Length to 91.4 cm Across European Marketplaces
Amazon has increased the maximum FBA box length from 63.5 cm to 91.4 cm for European marketplaces including the UK, Germany, France, Italy, and Spain. The change aligns Amazon's requirements with industry standards and gives sellers more flexibility in packaging.
Overview
Amazon is raising the maximum allowable box length for Fulfillment by Amazon (FBA) shipments across several European marketplaces, increasing the limit from 63.5 cm to 91.4 cm. The change, which took effect in 2025, applies to sellers shipping inventory to fulfillment centers in the UK, Germany, France, Italy, and Spain. This update brings Amazon's packaging requirements more in line with broader logistics industry standards and gives sellers greater flexibility in how they pack and ship their products.
Key Points
- Maximum box length increased — The longest side of an FBA shipping box can now measure up to 91.4 cm, up from the previous 63.5 cm limit.
- Width and height unchanged — The maximum width and height remain at 63.5 cm each.
- Weight limits unchanged — Standard boxes are still capped at 23 kg, with a 30 kg allowance for boxes containing a single oversized item.
- European marketplaces affected — The update applies to FBA operations in the UK, Germany, France, Italy, and Spain.
- No penalties for early adopters — Sellers who already shipped packages under the new dimensions before the official rollout will not face defect flags or additional fees.
Updated FBA Box Dimension Requirements
The revised maximum box dimensions for European FBA shipments are now standardized as follows. The maximum length has been extended to 91.4 cm, while the width and height caps remain at 63.5 cm each. For weight, the standard maximum is 23 kg per box, though Amazon permits up to 30 kg for boxes that contain only a single oversized item. These dimensions apply uniformly across all five affected European marketplaces, simplifying compliance for sellers who operate in multiple countries across the region.
It is worth noting that these measurements refer to the outer dimensions of the shipping carton itself, not the product packaging inside. Sellers should ensure their boxes fall within these limits after sealing and labeling to avoid receiving errors or shipment rejections at the fulfillment center.
Why Amazon Made This Change
The previous 63.5 cm length restriction placed Amazon's European FBA packaging requirements below the thresholds used by many major carriers and logistics providers. By increasing the maximum length to 91.4 cm, Amazon is aligning its standards with common industry benchmarks, which typically allow cartons of up to 90–100 cm on the longest side. This adjustment reduces friction for sellers who use standardized carton sizes across multiple sales channels, including their own direct-to-consumer operations and other marketplace fulfillment services.
Analysis & Recommendations
Why This Matters
FBA sellers shipping to European fulfillment centers can now use longer cartons, reducing the need to repack goods and potentially lowering inbound shipping costs. Multi-channel sellers benefit from standardized carton sizes across platforms.
