Solution 1 :
Not sure if there’s a way to add a custom display on the Multi-Preview, but you can create a custom display on an emulator:
Just go to Tools > AVD manager > Create Virtual Device > New Hardware Profile and add your required dimensions.
Solution 2 :
If you need just to preview your layout with the screen size you want, not view it with this size on the multi-window, it is still possible to do it from the split option on the top bar that appears when you edit your layout. Also on the Design one on the right of it if you don’t want to see the code.
The way to change the size to your custom one is the same as before, you create your Hardware Profile from AVD or select it from the ones presets.
If you want to see it on the multi preview tab, as I said on the comment to your first post, on android studio 4.0 it will be possible to use custom sizes on multi-preview, I had not yet seen any tweak or info about doing it on android studio 3.6
Problem :
With android studio 3.6 we can preview the xml in different sizes:
I need to preview a custom size 1.560 x 720, its possible to configure it?

I already knew this thanks, but I want to add my screen to the multi preview feature

Sadly this way you can’t make the preview’s tab float or convert it to a window which, in my case, is kind of problematic as I always type layouts and don’t use the design tab

I think that android 4 will introduce Pixel devices and project locales but no custom devices

Yep, I just realized that understanded it wrong. Maybe they don’t keep it to pixel ones on the future, I will edit my answers, sorry!
