Both Weight Rule and Weight Limits by Product can restrict the weight of products a customer can purchase, but they differ in how they are configured and what they are best suited for. Choose the one that fits your needs.
Weight Rule | Weight Limits by Product | |
|---|---|---|
Checkout rules consumed | 1 per rule | 1 total |
Limit scope | All products / Collections / Products & Variants / Cart-wide | Products & Variants |
Per-variant individual settings | △ (※1) | ✓ |
Total weight limit across variants | △ (※1) | ✓ |
Cart-wide / multi-product combined limits | ✓ | — |
Weight unit configuration | One shared unit for the whole rule; products with a different unit must be either converted or excluded | Set individually per row (product/variant), or automatically follows the product's own registered unit. Always compared in grams internally, so there is no unit-mismatch setting to configure (※3) |
Bulk configuration across products | ✓ | — |
Automatic application to new products | ✓ (※2) | — |
Best for | Stores with large catalogs / Stores that frequently add new products / Cart-wide weight restrictions | Stores with many types of weight restrictions Stores that need fine-grained per-variant weight control |
(※1) Can be achieved by creating individual rules, but each rule consumes one checkout rule.
(※2) When "All products" or a collection is specified as the eligible items, any newly added products are automatically covered by the rule.
(※3) See "Weight Limits by Product: Settings" for a note on products with mixed variant weight units.
