Otherwise, the water will leak the wax ring as well as the connecting point between the flange and toilet bowl. That is why the toilet flange needs to be perfectly even with the floor as well as the needs to be perfectly sealed with wax rings.

How far should the toilet flange sit above the floor?

The correct flange height should be measured before installing the commode. If you remove the toilet then you will be able to measure the toilet flange height from the floor. 

However, the average height of the flange is ⅓ or ¼ inches from the finished floor. In this range of height, nearly any style of waxed rings may be utilized as well as it will provide a satisfactory sealing. 

This will allow the water continuously from the bowl to the inner pipes through the flange without any leakage. The wax ring will not have any air gap issues as well as the ring will last long.
