Charge accurate shipping for bulky items with WooCommerce Table Rate Shipping 3.7.0
You can now build shipping rate rules based on the total volume of items in the cart, alongside the existing weight- and count-based options. For stores selling furniture, large appliances, or other bulky, packaged goods, dimensional size is often a better proxy for shipping cost than weight alone — this gives you a rule that reflects that.
How to get it
Update to WooCommerce Table Rate Shipping 3.7.0, then set up a volume-based rate rule under WooCommerce > Settings > Shipping.
