The exact dimensions can be found in the product description of the individual ramp molds
The dimensions of the ramps are chosen so that the different ramps fit together. Similar to Lego, the dimensions of our ramps are multiples of our basic dimensions. For ramp molds, this is 3 x 3 x 3 cm. This ensures that, for example, the bench is just as high as the curb or the stairs. 3 stairs on top of each other are, for example, as high as a small quarter.
