I got my old MacBook (the last model with integrated DVD drive) in the bag. That model has room. If you have a newer and flatter model, you can use this bag without any problem.
The Surface Book 2 fills it out pretty perfectly, so the outside dimensions of the Surface Book 2 probably match the inside dimensions pretty closely
Height 2.30 cm
Length 23.20 cm
Width 31.20 cm
