The invention relates to a grouping of cylinders in a drying section of a paper machine, in which drying section a paper web and a wire are carried meandering from a first heated drying cylinder onto a leading cylinder and from the leading cylinder further onto the next heated drying cylinder. A drying group consists of a number of subsequent groupings of cylinders, whereby, in each grouping of cylinders, the drying cylinders and the leading cylinders are placed, in relation to one another, substantially at three different height levels, so that the drying cylinders with larger diameter are placed at a height level Y1 and the drying cylinders that have a diameter smaller than said larger diameter are placed at a height level Y2. In the groupings of cylinder the leading cylinders are placed at a third height level Y3.
