Apparatus and method for changing one or several dimensions of a load space in a working machine, when the dimensions are width, height or length. In the method the weight of the load in the load space is determined or the weight of the load in a full load space is predicted on the basis of said determination and the current value of the dimension; a new value is calculated for the dimension by means of which it is possible to reach a set maximum quantity for the part of the weight of the load; and the dimension of the load space is adjusted either gradually or at once to a position according to the new value. In the method for changing the height of the load space the quantity of the load or a change in the quantity of the load in the load space is determined automatically; and the current height of the load space is adjusted to a new height or in accordance with a predetermined change of height that corresponds to the quantity of load according to a set dependency, wherein the height of the load space is at the same time kept as low as possible during the loading or unloading.
