How to set scale?

Hello,

I created new React App a few days ago and I have a problem.

All elements are bigger, than on the design although it is the same size (1920x1080). And that's because my default system scale is 125%. When I have changed it into 100%, it worked fine. But I want my app to be well displayed on all my users devices (even if they have scale 125% as system default).

In my index.html I have this line:

<meta name="viewport" content="width=device-width, initial-scale=1" />

Do you know what's the problem with it?
