How do I adjust weight and dimensions for specific options in V3?
If your options or variants have different weights and dimensions, you’ll want to enter those if you’re using real-time shipping quotes.
First, go to Products > View and edit the product you want to change. Scroll down to the Variants section. Above the variants on the right side, click Edit Columns. Check the boxes for Weight, Width, Height and Depth. Enter the weights and dimensions for each sku as needed.
Note that you may need to scroll to the right to see the new columns.
Save when finished.
