At our store we are setting up our shipping on Shopify. When setting up our rates we are curious if we need to put the exact weight in for all of our products, or can we use the dimensional weight from our boxes ((LxWxH)/166)?
Yes, it is a good idea to use either the dimensional weight or the actual weight, whichever is higher, since Shopify Shipping only considers weight for calculating rates.
Please note that this is a workaround solution. When customers buy multiple products at checkout, you may not receive accurate shipping rates. It is advisable to cross-check the total order weight before generating the shipment to avoid losing money.
Alternatively, you may consider using an app like the Multi Carrier Shipping Label app, which is capable of handling box packing scenarios.
