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 left-hand 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 on it and displays a symbol such as "⌘." You'll find it toward the bottom left corner 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 such as Microsoft Word and Adobe Creative Suite products. Windows Change Font Size Buttons 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, Windows Central describes the process: Right-click on your desktop and select "Display settings."Use the slider to change the size of the text.

"You can quickly open it by using the keyboard shortcut Windows key and the plus sign (+) to zoom in and minus sign (-) to zoom out. Use Windows key and 'Esc' to exit the magnifier.

Note that some websites have their font size set and the browser can’t always change it.Safari: From the Safari menu, choose Preferences.
