Just a touch smaller than the opening

Filter labeled as correct size , it’s a little smaller than the opening which causes it to whistle or fall out of place. When unit comes on you can hear filter suck back into a position

Fits perfectly into the furnace where other filter brands have fought to fully go in. The price of these filters are excellent as well
