How to change the font size in my browser

Internet browsers

Adjusting the size of objects in your browser can make them easier to view or read. To change the font size, we recommend using the zoom function as changes are quick and easy to edit or revert. It also works with all types of content. The following sections show you how to quickly adjust the size of both font and images on a page or only the font. To proceed, select your browser from the list below and follow the instructions.

Note

When following the steps below, you are zooming in on the page rather than changing the font size chosen by the page's creator. As a result, the font size and type remain at their default values when you print a document or page from the Internet.

Tip

Using any of the browsers listed below, you can change the size of the font using your keyboard and mouse. Press and hold the Ctrl key, then move the mouse wheel up or down. Alternatively, you can press and hold the Ctrl key (or Command on Mac), then press + or - (plus or minus) to increase and decrease the font size.

Tip

All major browsers also support pressing Ctrl+0 (zero) to change the font to its default size.
