Best practice for number of products in cart in Adobe Commerce

This article provides best practices for the number of products in a cart in Adobe Commerce. The maximum recommended number of products is 100.

The potential site impact of exceeding the limit is:

• An increase in data retrieval operations, validation of cart items, checks for price rules applications, tax calculations, and totals calculations.
• An increase in the time for mini-cart rendering including cart rendering time, checkout flow rendering, and execution, leading to performance degradation.
• Increase in the page loading time for all site pages where the mini-cart is present, leading to performance degradation.

Adobe Commerce Best Practices for cart limits are:

• Up to 100 products in a cart
  • the product works, meeting performance targets for response time.
• Up to 300 products in a cart
  • the product works, but response time increases above targets.
• Above 500 products in a cart
  • the cart and checkout flows are not guaranteed to work.

Affected products and versions

Best practices

• Split orders into several smaller orders with a smaller number of rows by leveraging the Add Item by SKU feature.
