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.
