The present invention relates to a gradient coil system for magnetic resonance imaging (MRI) systems and to a magnetic resonance imaging (MRI) system comprising such a gradient coil system. Magnetic resonance imaging systems comprise at least a main magnet system, a gradient coil system, a RF system and a signal processing system. The gradient coil system according to the present invention comprises at least two X primary coil-like elements (X 1 <SUB>pc</SUB>, X 2 <SUB>PC</SUB>), at least two Y primary coil-like elements (Y 1 <SUB>pc</SUB>, Y 2 <SUB>pc</SUB>) and one Z primary coil-like element (Z<SUB>PC</SUB>) providing a modular gradient coil system, wherein the at least two X primary coil-like elements (X 1 <SUB>PC</SUB>, X 2 <SUB>PC</SUB>) have mutually different linearity volumes by themselves or in combination with each other, the at least two Y primary coil-like elements (Y 1 <SUB>PC</SUB>, Y 2 <SUB>PC</SUB>) have mutually different linearity volumes by themselves or in combination with each other, and the one Z primary coil-like element (Z<SUB>PC</SUB>) is placed between the X primary coil-like elements (X 1 <SUB>PC</SUB>, X 2 <SUB>PC</SUB>) and the Y primary coil-like elements (Y 1 <SUB>PC</SUB>, Y 2 <SUB>PC</SUB>).
