return air grille size


Should his ratio of floor 1 to floor 2 return size be the same as the ratio of floor 1 to floor 2 heat demand? If he changes the balance and starts pulling a greater percentage of return air from the basement won't that also pull a greater percentage of supply air to the basement?

Or will it tolerate a lot of variability in the balance?

Trying to learn something today.

If there isn't any doors to block the flow of return air then there will be little difference in the overall performance.
