Several paper grades are finished in a supercalender (1) or similar calender types in order to increase the smoothness, gloss and other properties of the paper. According to the invention, the method for producing coated and calendered paper or paper board, comprises steps of coating a sheet of paper or paper board and bringing the sheet containing water to a calender (1), leading the sheet in at least one nip formed by two rolls (18, 19) of the calender (1) and imposing simultaneously heat and pressure on the sheet in the nip in order to treat the surface of the web, whereby also water is removed from the sheet, removing water from the sheet before winding in such an extent that the moisture content of the sheet is adjusted to a value of 4.0% or less, leading the treated sheet to a winder (21), and winding the sheet on a roll.
