Is there a way to change the font size? I’d like to make it a bit bigger but leave the graphics the same.
Is this on mobile or desktop?
Also, what graphics? 
Also, if you increase the font size without increasing the size of the other elements, then a lot of things will probably end up mis-aligned.
Also, no, there’s no in-game option to change the font size, but it is possible if you’re playing via a browser and are prepared to play with CSS styles yourself.
Windows font scaling is the best approach for this. I set the scaling to 200% I think? For my 2560x1440 displays. I think people use 300-400% for their 4k screens depending on factors. You might need even more on a very small laptop display.
Way more effective doing it that way than program-by-program.
This being said - hold CTRL and scroll up and down. That increases the text scaling of that particular website and it remembers so it’s a permanent change. It seems to work on APEX well enough.
