Amazon FBA Capacity Limits: What You Need to Know in 2025

For businesses leveraging Amazon’s Fulfilment by Amazon (FBA) programme, understanding Amazon’s FBA Capacity Limits is crucial in 2025. These limits directly impact inventory management, operational efficiency, and overall profitability. 

Whether you are a seasoned seller or new to the Amazon ecosystem, navigating Amazon storage limits effectively can give you a significant competitive edge.

What Are Amazon FBA Capacity Limits?

Amazon FBA Capacity Limits refer to the restrictions Amazon places on the quantity of inventory sellers can store in its fulfilment centres. These limits are based on several factors, including sales history, product demand, and storage capacity at Amazon’s warehouses.

  • Amazon storage limits are measured in cubic feet and apply to all inventory types.
  • These limits ensure optimal use of space and help Amazon manage its logistics efficiently.
  • Sellers must track these restrictions to avoid penalties or disruptions to their supply chain.

Amazon updates its capacity algorithms frequently, considering global trends and evolving marketplace dynamics. This ensures fair allocation for sellers while maintaining warehouse efficiency.

Why Does Amazon Impose FBA Storage Limits?

The primary reason for imposing Amazon FBA storage limits is to maintain efficiency across its vast network of warehouses. With millions of sellers and products, ensuring adequate space for high-demand items becomes essential.

  • Seasonal surges: During peak seasons like holidays, space is at a premium, requiring tighter restrictions.
  • Minimising inefficiencies: Overstocked, slow-moving, or unsellable items can reduce operational productivity.
  • Encouraging active management: By implementing these limits, Amazon motivates sellers to manage their inventory more strategically.

Additionally, storage limits ensure that newer, fast-selling products can access warehousing facilities, benefiting both sellers and customers.

How Are FBA Capacity Limits Determined?

Amazon uses a mix of metrics to calculate storage limits for each seller. These include:

  1. Inventory Performance Index (IPI): A scoring system evaluating inventory health based on sell-through rates, excess stock, and stranded inventory. Maintaining a high IPI score is key to securing higher Amazon storage limits.
  2. Sales performance: Consistent sales history often leads to greater storage allowances.
  3. Fulfilment centre capacity: Amazon adjusts limits based on regional or warehouse-specific constraints.
  4. Product Seasonality: Products with fluctuating demand due to seasonality may influence the storage allocation.

How to Check Your FBA Storage Limit?

To stay compliant with Amazon FBA storage limits, it’s essential to monitor your allocated capacity regularly. Here’s how:

  • Log in to Seller Central and navigate to the Inventory Dashboard.
  • Look for the FBA Capacity Monitor, where you’ll find your current usage, limit, and performance metrics.
  • Use the Capacity Manager Tool to plan inventory adjustments proactively.

This transparency helps sellers avoid surprises and maintain smooth operations. Ensure to check for updates regularly, especially during sales events or festive seasons, when limits may change.

How to Use the FBA Capacity Manager?

The Amazon Capacity Manager is a powerful tool that allows sellers to manage and optimise their storage limits effectively. Here’s how to make the most of it:

  1. Monitor Real-Time Usage: Get an up-to-date view of your storage capacity to prevent overages.
  2. Request Additional Storage: Submit bids for additional capacity when needed, subject to approval.
  3. Analyse Forecasts: Use predictive analytics to align inventory levels with upcoming demand trends.
  4. Budget Wisely: When requesting additional storage, consider the cost implications and balance them against projected sales growth.

The Amazon Capacity Manager simplifies inventory planning and ensures you maximise your selling potential. Learn more about it here.

How to Increase FBA Storage Limits?

If your business is scaling and requires more space, there are actionable steps to increase your FBA storage limits:

  • Improve Your IPI Score: Focus on better sell-through rates, reducing stranded inventory, and removing excess stock.
  • Optimise Inventory Levels: Regularly remove slow-moving items or liquidate unsellable inventory.
  • Participate in Peak Programmes: Enrolling in programmes like Small and Light or specific promotional events may offer additional storage space.
  • Demonstrate High Sales Velocity: Higher sales volumes often translate to increased storage allowances.

Remember, increasing limits often requires consistent, data-driven efforts rather than short-term fixes. Sellers who utilise external storage options as a buffer may also experience fewer disruptions during peak demand periods.

Challenges of Amazon FBA Storage Limits

Navigating Amazon FBA storage limits comes with its own set of challenges:

  • Limited Space During Peak Seasons: Sellers often face tighter restrictions when they need more inventory space the most.
  • Stranded Inventory Issues: Items with improper labelling or low demand can take up valuable space, reducing efficiency.
  • Overage Fees: Exceeding your limits can result in hefty penalties that impact profit margins.
  • Lack of Predictability: Sudden changes in storage policies or space availability can disrupt planning.

By understanding these challenges and planning proactively, sellers can avoid costly mistakes and maintain smooth operations.
