Android emulator screen size is not same as preview screen

Question

As you can see in below image, I wrote a sting of numbers and their appearance on emulator screen and Preview of Studio is different. On emulator screen on left, I have marked the space with red color, but if you see on the Preview window on the right, there exists no space. How do I make the Preview screen size as same as my emulator screen?

For the emulator, I have set screen size as 5.5 inch and resolution 720x1280. The text size I have set to 66sp in xml file.

If you just want to change the preview screen size you can select another reference device in the drop down where you currently have the Nexus 4 selected, and change it to the same size as the emulator:
