Best Laptop Screen Size for UE4

Hi there,

I’m currently developing on a 13inch laptop (Macbook Pro to be exact), the problem i’ve been facing is the editor, content browsers, detail panel cramp into such small screen size at some point it is an annoyance.

I’m thinking of an upgrade, what kind of laptop size would you suggest? 14 inch or 15inch?
I’m bias towards 14inch for the portability but feared i would face the same problem again.

Thanks and best regard.
