The Delta upper case Δ or Delta lower case δ symbols in Microsoft Word, Excel, PowerPoint, or Outlook.  Both in Office for Windows and Office for Mac. 

Delta (uppercase Δ / lowercase δ) is the fourth letter of the Greek alphabet. It’s the “d” sound in Modern and Ancient Greek.

Delta uppercase Δ symbol is used in mathematics to represent change in a variable, while the lowercase symbol δ indicate small quantities in mathematical proofs, involving limit, a key concept within calculus. 

To us non-mathematicians Delta uppercase Δ is just a triangle while δ is circle with funny squiggle on top <g>.

How Delta upper case and Delta lower case look in different fonts. 

Here’s some examples of how the Delta upper case and Delta lowercase symbols look in common Office fonts in Word 365. 

Delta upper and lowercase symbol codes 

These are the important code numbers or values you’ll need to enter the two symbols

Use the Alt + X shortcut in Word for Windows, for example type 0394 then Alt + X to enter Δ  

Or enter the value into Character Code fields in Symbol dialog boxes to jump to that symbol. 

Delta uppercase symbol Δ           U+0394

Delta lowercase symbol δ           U+03B4 

Quick access for commonly used symbols. 

If you use a symbol often, a fast way to enter it is AutoCorrect. 

Once in a document you can copy it to AutoCorrect and make your own shortcut. 

Word, Excel, PowerPoint and Outlook 

Insert | Symbols | Symbol and look for the Delta symbol using Character Code 0394. 

Window 10 Emoji Panel

The Windows 10 Emoji Panel has the Delta symbol Δ.  Use Win + . (period/fullstop) to open the panel.
