How to choose the size of the Landing Page?

Good afternoon.
Prompt please to the beginner, on account of the size of the layout for landing pages (width and height).
The maximum resolution all of the computers 1920px. So you need to use it?
But, there are still monitors like 1280px etc.. Then a workspace to do is 1280px?
I imagine it as:
in the figma (I like) to create a frame (of artboard) with the size of 1920x??? (arbitrary height)px. Then connect the grid indented on both sides (right and left) at 320px (1920-1280=640/2=320).
And therefore work only within the boundaries of the workspace (1280px).
For example, I main the screen height for 1280 want to make it 900px. Inside this width I adhere to all the rules of typesetting? place the objects.
Sorry for the stupid question, just can't find in the Internet the normal article, wherever available was due to what permissions to do layouts. A little confused. Can share the link to the article or tell me Joon?)))

Look on the Internet "ready psd mockups download" , download , look , what are there sizes . You can look for ready-made site layouts with the grid to see how everything is done. This is a topic, do different...
I think it is necessary to make several layouts of one landing. One layout for wide screens, one for tablets and one for phones.
For a wide for example to arrange the blocks in 4 columns, tablet, 2 columns of phone numbers in 1 column
here's an example here
