How much actual play time is there in a typical NFL game? Vs commercial time?

15 minute quarters but 90 seconds of commercial between each and every play.
Please advise

They don't show commercials after every play. A typical Sunday game start at 1 and is over at 3:30 -4
The Super Bowl is much longer because of the extra long halftime show

@FreeSpirit1 the most recent times I’ve watched I rarely do it was every other down so 1st and 3rd down ran opposite 2nd and 4th down with an additional commercial break at every time out or penalty called.
