However, at times these adventures can go wrong, and you may end up with completely changed fonts on the web browser making it extremely difficult to read or write.

So, you may be wondering why your browser font is so small. Or why it’s not the same. Well, read on to learn how to fix this by following our troubleshooting guide.

Why did my browser font suddenly change?

It really is a nuisance when this happens, and when it does it is due to either DPI scaling level, screen resolution, or something getting changed to the default text size.

Another reason why this could happen is your system getting infected with malware, but hopefully, that is not the reason. Just to be on the safe side, perform a full antivirus scan.

Quick Tip:

Use a browse with simple and straightforward customization options. We recommend Opera. It lets you install and create your own themes as well as easily adjust font type and size.

The browser runs on a Chromium engine and gets frequent updates, which makes it very responsive and reliable. It includes a free adblocker, a VPN, social media integrations, and more.

What fonts are built into browsers?

Web-safe fonts are the obvious choice in standard web design. Thus, by choosing a web-safe font, you can ensure that your text will always appear as intended.
