Correct Coolant Engine Running Temperature

Could someone tell me the correct coolant engine running temperature?
As the engine warms up from cold it depends which thermostat you have fitted. Either 82 C or 88 C normally. Then as you continue to drive the coolant will get a bit hotter around the 90/92 C mark. This is the coolant temperature as measured at the thermostat housing.
