If you're using a mobile browser on Android that doesn't allow overriding websites that disable zoom (or using a website that defines font sizes in vw/vh), check your accessibility settings, there should be a shortcut for triple-tap to enable a zoom function. Some devices have other magnifying functions as well. My tablets and phone all have the basic magnifier function; my LineageOS (android 7 & 8) tablets additionally have a screen zoom/dpi setting to modify how large both pictures and text appear, and my samsung tablet (Android 10) has this and also a text zoom function. There's also a minimum view width setting in developer options since at least Android 8, to ensure interfaces aren't too small on mobile (this only goes one way though-- there's no maximum view width and no height controls). It doesn't help with everything, but the triple-tap zoom is quite useful.
