How to optimize website size in photoshop?

Question

User interface

Tell me please. I recently started learning the basics of web design. I started creating a prototype landing page (yes, yes, for now in Photoshop, although I heard that it’s better to do it in indesign or in a sketch). So this question arose, or rather a few questions: How to correctly set the page size (960 pxX1000px?) And how to properly build the size of the modular grid? Is it possible to use ready-made templates for these grids. In general, I want to find out the regularity of these sizes.

Fsh and AI are needed only for rendering site details. Don't torture yourself, install Adobe XD and download ready-made bootstrap grid 1920x1080
