A dryer section for a paper machine including dryer groups with single-wire draw, each of which includes drying cylinders, reversing cylinders or rolls arranged in gaps between the drying cylinders, and a drying wire for carrying the web under constant contact with the wire over the drying cylinders and reversing cylinders or rolls so that the web enters into direct contact with the drying cylinders and that the wire enters into direct contact with the reversing cylinders or rolls. In at least one of the groups with single-wire draw in the dryer section, four drying cylinders are placed in pairs side by side and one above the other so that the upper pair of cylinders is placed at a lower level than the other cylinders in the group.
