Expanding kitchen, do I need more duct?

I am building an addition on to my kitchen. Existing room is 16ft x 11ft. with
one 15" register and no return. The room is open to the family room which has three registers and one return, it also is open to the front hallway & the front living room which have three more registers and one return. The new size of the kitchen is 16ft x 21ft.
Can I just extend the existing run or will I need more capacity?

hard to say out seeing a drawing... I would say you'll need more than one vent in the kitchen.. More likely one under the toe kick of the sink, one under window, and near a door going outside.

Do you have a drawing that you can share with us?
