With this app, you can create rules based on different conditions, like:<\/p>\n\n\n\n
- \n
- Set a Minimum Weight (e.g., at least 5kg to qualify for bulk shipping) or a Maximum Weight (e.g., no more than 20kg to avoid freight charges)<\/li>\n\n\n\n
- The total weight is a multiple of a specific number, which is useful for shipping in fixed-size crates<\/li>\n\n\n\n
- Show custom warning messages directly in the cart when these weight limits are not met. <\/li>\n<\/ul>\n\n\n\n
Now, let\u2019s understand the process for setting up weight limits in Shopify using this app.<\/p>\n\n\n\n
Steps to Set Product Weight Cart Rule in Shopify (Using App)<\/h2>\n\n\n\n
Start by installing the MIT Cart & Order Limits<\/a> Shopify app from the Shopify App Store. Then, follow the steps below to configure a product weight rule in your store.<\/p>\n\n\n\n
Step 1: Create a New Weight Rule<\/h3>\n\n\n\n
From the app dashboard, navigate to the Weight Rules<\/strong> and click View rules<\/strong>.<\/p>\n\n\n
\n![\"navigate](\"https:\/\/meetanshi.com\/blog\/wp-content\/uploads\/2026\/03\/select-weight-rule.png\")
<\/figure>\n<\/div>\n\n\nThen, click on Create a New Rule<\/strong>, and you will see an interface where you have to configure the cart weight limits and define when the rule should apply.<\/p>\n\n\n\n
Step 2: Define Weight Limits<\/h3>\n\n\n\n
Assign a title to your rule for internal tracking and configure the specific weight boundaries for the cart.<\/p>\n\n\n\n
You can set the following limits:<\/p>\n\n\n\n
- \n
- Minimum Weight for Cart –<\/strong> The minimum total cart weight required to allow checkout<\/li>\n\n\n\n
- Maximum Weight for Cart – <\/strong>The maximum total cart weight permitted in the cart<\/li>\n\n\n\n
- Multiple Weight for Cart –<\/strong> Restricts checkout unless the total cart weight is in multiples of a specified value<\/li>\n<\/ul>\n\n\n
\n![\"Define](\"https:\/\/meetanshi.com\/blog\/wp-content\/uploads\/2026\/03\/set-limits-3-1024x627.png\")
<\/figure>\n<\/div>\n\n\nFor each limit, you can write a custom warning header and message. Use dynamic variables like {minimum_weight} or {current_cart_weight} to show customers exactly what they need to change to proceed.<\/p>\n\n\n\n
This helps you display clear messages to customers.<\/p>\n\n\n\n
Step 3: Set Rule Conditions <\/h3>\n\n\n\n
Next, decide when the weight rule should apply by adding conditions. The app allows flexible rule creation using AND \/ OR logic.<\/p>\n\n\n\n
Click on Conditions next to Limits in the dashboard and select your conditions. <\/p>\n\n\n\n
- \n
- Choose the attribute (such as product, collection, customer tag, etc.)<\/li>\n\n\n\n
- Select the logical operator and value<\/li>\n\n\n\n
- Add multiple conditions if needed<\/li>\n<\/ul>\n\n\n\n
![\"Set](\"https:\/\/meetanshi.com\/blog\/wp-content\/uploads\/2026\/03\/set-conditions-2.png\")
<\/figure>\n<\/div>\n\n\nYou can combine conditions using AND \/ OR logic to precisely control how the rule works.<\/p>\n\n\n\n
Once the conditions are configured, click Save<\/strong> in the top-right corner.<\/p>\n\n\n\n
The rule will now be active on your cart page, preventing customers from proceeding to checkout unless the total weight satisfies your requirements.<\/p>\n\n\n\n
This is how it will look: <\/p>\n\n\n

Using weight-based cart rules helps manage shipping and keep order handling efficient. To use these rules effectively, follow these best practices:<\/p>\n\n\n\n
- \n
- Ensure your minimum and maximum weight rules match the restrictions set by your shipping partners. This prevents checkout for orders that carriers may refuse or charge extra for<\/li>\n\n\n\n
- Use dynamic variables in your warning messages so customers know exactly how much more (or less) weight they need to add to proceed<\/li>\n\n\n\n
- Apply different weight rules for wholesale and retail customers. For example, you might require a higher minimum weight for B2B orders to ensure bulk shipping efficiency<\/li>\n\n\n\n
- Make sure your product weights are correctly updated in Shopify. Once the weights are accurate, you can easily set shipping rates per item<\/a> so your shipping charges match the cart contents<\/li>\n\n\n\n
- Verify the cart warning pop-ups or banners are mobile-responsive and do not block the Checkout button, as this can frustrate users<\/li>\n\n\n\n
- If a customer exceeds a weight limit, consider adding a link in the warning message to your Shipping Policy or a contact form for custom freight quotes<\/li>\n<\/ul>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
Setting weight limits can help you control shipping costs and manage fulfillment more efficiently. <\/p>\n\n\n\n
