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 the font only, keeping images their default size. 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, then move the mouse wheel up or down. Alternatively, you can press and hold the Ctrl (Command on Mac), then press either + or - (plus or minus) to increase and decrease the font size.

All major browsers also support pressing the Ctrl and 0 (zero) at the same time to change the font back to its default size.
