The present invention relates to a method for coating of a fibrous web. According to the method a coating color with pigments is applied to the surface of the web and dried in order to form a coated web. The invention comprises using a coating color which contains pigments having a steep particle size distribution, a maximum of 35% of the pigment particles being smaller than 0.5 &mgr;m. The coating color is spread on the surface of the web with a coating speed of at least 1450 m/min, preferably over 1600 m/min. The coating pigment having a steep particle size distribution gives rise to a coating color which solidifies at much lower dry substance than conventional coating colors. In this way coating can be controlled at high speed without runnability and quality problems.
