Thanks in advance for any help!

In the document I'm creating I am hoping to autopopulate 2 or more text content controls with differing values based on one dropdown option.

e.g: dropdown "Choose size" has 2 options: 'Large' and 'Small'.
when a size is chosen I would like a value for its height to populate in textbox 'Height' and a separate/different value for its width to populate in textbox 'Width'

Is this do-able the way I have mentioned above? I know how to populate when only one value is required. If there is an easier/better way of completing this please point me in the right direction!
