Enough Return Air?

I have a 2,932 square ft. ranch with full basement. Home was built in 1983 There are only two return air vents in the entire house. Both vents are located on the floor are panned joist returns. The basement is finished so converting the panned joists would be difficult.

Basement return air vent is 13.5 in x 13.5 in

Upstairs return air vent is 29.25 in x 12 in

Should I increase the size of the return air vents?
