400cfm/ton, a 60,000 btu furnace probably has a 3 ton drive. 1200 cfm.
How do you calculate cfm for a furnace?
To find required airflow divide the rated furnace input by 10,000 Btu. 100,000 divided by 10,000 equals a factor of 10. 10 Times 130 cfm equals 1300 cfm. This airflow rule is applied to determine furnace airflow for three types of furnaces.
How big of a house can a 60000 BTU furnace heat?

Is it better to undersize or oversize a furnace?
it is best to have the right size furnace as oversize will cause too many on-off cycles. too small causes extended periods of running and the possibility that it won’t handle extreme cold. Better to oversize a little. If you oversize you may have wasted a little money and other resources.

How many cfm is a 4 inch duct?
Reviewing the chart, a 4” pipe will convey 395 CFM at 4500 FPM. This means that a 4” pick-up on a machine will use 395 CFM from the filtering system; or, if you know that a machine will require approximately 400 CFM to remove the waste, you should use a 4” pipe for that purpose.
What furnace size do I need?
A good rule of thumb for unit sizing is you will want a system that will provide you 40 to 45 BTUs of heat per square foot of your home. For example: If your home is 3,000 square feet, you’ll want a furnace that produces between 120,000 BTUs and 135,000 BTUs.
Why is 400 cfm a ton?
400 CFM per ton of air conditioning: The higher CFM is required to remove the sensible heat from the environment. However, if you have an environment that has high humidity then 350 CFM per ton is better. At the lower CFM the coil is colder and the air spends more time on the coil and increases dehumidification.
