Question about Dicota Perfect Skin

Keeps the following notebook in it HP Pavilion x360 11-n020nz. Fits well. I even have storage space for documents.
Serves more as a protective cover to prevent scratches because the material is soft. Perfect for my purposes.

The Dell XPS 13 fits in this bag, but the notebook has plenty of space in it. The length of the protective cover fits well, but it is about 5cm too wide.
