A gauge control method for a multi-roll type rolling mill including rolls which are displaceable not only in the thickness reducing direction but also in other directions, comprises determining the coeffts. of mill stiffness of the whole rolling mill stand as well as the inter-roll stiffness w.r.t. displacement or movement of the displaceable roll, determining the roll gap between the work rolls on the basis of the determined mill stiffness coeffts., the rolling load and the roll bending forces acting on the rolls, and controlling a screwdown device according to the determined roll gap.
