In the new Microsoft Edge , you can customize how fonts look when you're using immersive reader.
In Microsoft Edge, go to the website you want to read.
From the website's address bar, select Enter immersive reader. If you don’t see that option, then immersive reader isn’t offered on that particular website.
Next, select Text preferences.
Use the options under Text size, Text spacing, and Page themes to adjust your preferences.
