Changing the text size in your browser

Most popular web browsers feature a tool on the menu bar which lets you change the size of text on the webpages you are visiting. With this tool you can resize text on screen to a level you feel comfortable with. Where to find this tool differs slightly between browsers. You can also usually use the keyboard to increase or decrease text size quickly:

  • Ctrl key and the + (plus) key to increase text on Windows PC
  • Cmd key and the + (plus) key to increase text on a Mac
  • Ctrl key and the - (minus) key to decrease text on Windows PC
  • Cmd key and the - (minus) key to decrease text on a Mac

Please follow the guides below for your browser.

Please note that text size cannot be changed on some websites.
