When you encounter a screen with a font that's too small, you can easily adjust it with a few keyboard shortcuts, your browser, or settings within your computer.

The steps you take vary depending on what kind of computer you are using, a Mac or PC. Both types of computers allow you to quickly change font size, but the keys you need to hit are different.

Keyboard Shortcut for Zoom

If you're using a PC, hold down the "Ctrl" key while also tapping the "+" or "-" key. You'll find the "Ctrl" (which means "control") key on the lower lefthand part of the keyboard to zoom in and out. The "+" and "-" keys are located near the top right-hand corner of the keyboard. These actions trigger a zoom function, that lets you enlarge the screen you're viewing (the "+" sign) or zoom out using the "-" key.

On a Mac, the function is similar, except you'll use the "Command" key with the "+" or "-" keys. The "Command" key usually says command and displays a symbol like "⌘". You'll find it toward the bottom  of the keyboard. The "+" and "-" keys are near the top right-hand corner of the keyboard, similar to the configuration for the PC.

The zoom functions work across a variety of platforms, including browsers and various software, like Microsoft Word and Adobe Creative Suite products.

Windows Font Size Changes

You can also change the font size on your computer by using software commands. To change the font on your desktop or folders in Windows 10,  describes the process:

  1. Right-click on your desktop and select "Display settings."
  2. Use the slider to change the size of the text.

"If you want to temporarily enlarge a portion of the screen, use the built-in magnifier," notes Windows Central. "You can quickly open it by using the keyboard shortcut Windows key and the sign (+) to zoom in and minus sign (-) to zoom out. Use Windows key and 'Esc' to exit the magnifier. "

Mac Font Size Changes

In order to increase the font size on your Mac, you can lower your computer's resolution, change the size of the desktop icons, and increase the size of a sidebar size.

  1. From the main Apple menu, select System Preferences.
  2. Choose the Displays Menu.
  3. Choose the Scaled button in the Resolution area.
  4. In the next window, select a lower resolution size.

You can also change the font size for desktop icons by right-clicking on your desktop and choosing Show View Options. In the window that pops up, you'll see options for icon size, grid spacing, text size, and label position. Use these controls to alter your screen view until it meets your needs.

Browser Font Size Changes

You can also adjust the font size in your :

  • Firefox: Select tools -> options -> content -> font and color. Here you can change the default font size for the browser. Note that some websites have their font size set and the browser can’t always change it.
  • Safari: From the Safari menu, choose Preferences. Under the advanced tab look for the accessibility section and click the button for "Never use font sizes smaller than" and choose the font size that best meets your needs.
  • Internet Explorer: Select menu -> view -> text size. Or, depending on the version, there may be a slider in the bottom right corner you can move to increase the page size, much like zoom.
  • Google Chrome: From the Chrome menu, choose Preferences. This will open a settings window. Scroll down to the Appearance section, find the font size drop down and choose your font size, ranging from very small to very large.
