A method and apparatus for determining the profile of a coating layer of a paper or board web ( ). The method comprises application of a coating slip to at least one surface of the web ( ) at the coating head ( ) of a coating machine, the measurement of the transverse temperature profile of the web ( ) surface in at least a measurement point ( ) fitted after the coating head ( ), and the determination of the profile of the web's ( ) coating layer on the basis of the temperature profile measured in at least the measuring point ( ) fitted after the coating head ( ), whereupon a change in the temperature of the web's ( ) coating layer or in the difference of the temperature between the coating layer and the base web ( ) is at least almost proportional to the change in the coat weight.
