First layer smaller than second

During my first prints (total noob), I experience this problem. The first layer is smaller than the second layer(all the rest layers are ok..). 

That's the preview from the Prusa Slicer.

Any suggestions? Thank you in advance!

You will have a setting enabled by default called elephants foot compensation. It’s 0.2 by default. This shrinks the first layer in by the specified amount. 
This is to counteract the first layer squish needed to get good bed adhesion which would normally expand the first layer. However depending on how much squish you have on your setup the value may be too much. Personally on mine it’s set to 0.1 or off. Ymmv. If you have it to high the brim won’t actually connect to the part so will do nothing to help bed adhesion. You need to tune it for your setup.
