There are going to be allot of varying opinions on this one but it's fairly simple to get in a good ball park. You want between 600 to 800 feet per minute of air flow so you need to know the CFM of your air handler and then you can calculate it this way. Ftcube /min divide by Ft / Min = Ft square. At 1200 CFM for a flow rate of 800 Ft/min you get a result of 1.5 square feet which is 216 square inches. If you divide by 8 for the prefab 8 inch duct you need a 27 inch wide dimension or 16 X 13.5. Good luck on your project.

To determine how much $50,000 in 1965 would be worth today, we can use the inflation rate as a reference. The cumulative inflation rate from 1965 to 2023 is approximately 800%. This means that $50,000 in 1965 would be equivalent to around $450,000 today, reflecting the significant increase in prices over the decades. However, the exact amount can vary based on the specific inflation calculator used.
