Keyboard Shortcuts to Type Infinity Symbol in Windows

There are multiple ways in Windows to type infinity symbol.

Alt Code Keyboard Shortcuts for Infinity Symbol

Using alt code shortcuts is the easiest way to insert infinity symbol in any Windows application.

  • Turn on number lock on your keyboard.
  • Hold one of the alt keys available right or left side of the spacebar.
  • Type 8734 using the number pad on your keyboard.
  • This will make the infinity symbol ∞.

However, this method needs a keyboard with separate number pad. If you are using a compact laptop without separate number pad, check out this article on whether your keyboard supports alt code.

Alt + X Shortcut for Microsoft Word

In the above method, we use decimal code along with alt keys in keyboard. Alternatively, you can also use hexadecimal value with alt code. But this method will work only in Microsoft Word documents. Type the hexadecimal value 221E and then press alt + x keys together to make infinity symbol.

Using Symbol Utility in Office Documents

Do not worry, if keyboard shortcuts do not help you. There are many other alternate options available for typing symbols in Windows computer. Follow the below instructions on any Office documents like Word, Excel, PowerPoint and Outlook.

Using Equation Editor in Office Documents

Sometimes, you may be frequently using equations involving mathematical operator like infinity, pi, division and other symbols. In this case, you can use the equation editor instead of keyboard shortcuts.

  • Open Excel, Word or any other Office application.
  • Go to “Insert > Symbols > Equation” menu item.
  • This will open equation editor and you can find infinity symbol under basic math operators.
  • You can also find predefined equations and formulas that you can insert directly by selecting.

The only problem with equation editor is that you have to manually adjust the inserted equations to align them with other text content. Especially, printing equations will be difficult as they are not regular text and align inappropriately.
