Weight limits by product is a feature that lets you set different minimum and maximum weights for each product or variant. You can also set a total weight limit that combines the eligible variants within the same product.
When you enable weight limits by product, it uses only one checkout rule overall, regardless of how many products or variants are configured. Weight rule uses one checkout rule for each enabled rule.
Prerequisite: Due to Shopify's limit, the checkout rules you can enable across quantity, price, weight, bundle, and customer rules combined are limited to 25 per store.
You want to set different maximum and minimum weights for each product or variant
You want to limit weight by combining multiple variants of the same product
You want to configure many products while keeping the checkout rules used to just one
Limit | Evaluation unit |
|---|---|
Weight limit | Weight of the same variant |
Total weight limit | Combined weight of eligible variants within the same product |
You can set a common value for the product and override it individually only for the variants that need it. You can also exclude specific variants from the weight limit or the total weight. Weight is aggregated by multiplying the variant's weight registered in Shopify by the quantity.
Note: Variants without a weight set in Shopify are not included in either the weight limit or the total weight limit evaluation.
Comparison | Weight rule | Weight limits by product |
|---|---|---|
Best suited for | The same condition applied to a broad set of items | Different conditions for each product or variant |
Combining different products | Yes | No |
Combining the entire cart | Yes | No |
Weight unit | One unit for the entire rule | Specified per product or per total, or follows the product's registered unit |
Checkout rules used | One per enabled rule | One for the entire feature |
Tip: Weight limits by product uses one checkout rule. If you have no other checkout rules enabled, you can use the remaining 24 for other rules.
If you specify "All products," a specific collection, or a specific tag as the eligible items for a weight rule, new products that match the condition are automatically included. With weight limits by product, new products require individual configuration.
Weight rule requires you to select a pricing plan before you can create a rule. With weight limits by product, you can enter the settings, but a pricing plan is required when you enable the feature.
Prerequisite: To display product messages on the product page, enable the app embed in your main theme. If you only use the limit at checkout, the app embed is not required.
