How to add Weight to an item Variation?

Q: Our Shipping is based on the weight of an item. In a Simple product we can add its weight and dimension, but cannot find a way to add this to a product with Variations.

A: You need to add weight & dimensions for each variation in the variation tab. You can do this quickly by using the bulk edit dropdown just before all variations. So to set the weight for multiple variations of a Product, go to the Product window, then scroll down to the Product Data window. Next go to your Variations Tab. Click on the Dropdown window and you will see the items you can set for the product’s variations. This includes regular prices, sale prices, stock, weight, width, length and height.
