For a 5-ton HVAC system, the recommended size for the air return duct is typically around 20 inches by 20 inches or larger, depending on the design and layout of the system. The exact size may vary based on the specific airflow requirements, duct length, and other factors such as the type of filter used. It's crucial to consult with an HVAC professional to ensure proper sizing and efficiency. Properly sized returns help maintain balanced airflow and optimal system performance.
Your ac contractor or engineer will determine the correct size.
What size supply register are you using? The return register should match the supply. If the return is too small you will have positive air pressure in the room, and if too large you will negative air pressure.

You need a 5 ton unit for that size house.
The best rule of thumb I have found is: Length X Width / 144 * 288 = Max. CFM I have used this formula to size many HVAC systems. It has always worked. For example, a 5 ton unit should have a 30x36 grille(2-18X30 filters). (30x36)/144*288=2160 max cfm. Return Air should be sized at 200 square inches per ton according to AirMate and other filter grille manufacturers to achieve 2.0 static pressure. The Return Air Duct should have an unobstructed 6 square inches per 1000 BTU of cooling.
