Some mods work fine with the ui scale mod and some does not.
My eyes are not the best and I played with a 2560x1440 resolution and it was really bad. I used ui scale mod and some mods that had no problems with it.
I got a 4k screen then, and if you also have one the best solution would be to use the 2x scale that you can enable from the wot settings without a mod .. 95% of the mods work with that .. all ui elements should have the size of 1920x1080 resolution but the world is rendered in full 4k.
