You can increase or decrease the size of the text in your document in 2 ways:
First, select the text whose size you want to change
Then, Click the ‘Home’ tab (see the diagram below)
Under the Font group – Just to the right of the box containing the Font types, you will find a small box which contains the available sizes you can use to change the size of the text in your document.
Click on the small down arrow next to this box, a list of size options will appear on your screen.
Click on the size you want or place the pointer of your mouse over the available sizes to get a preview of how it would look on the text you have selected.
Tip: You can also use the mini toolbar to change the size of the text in your document. This is the second way you can change the size of the text in your document.
