What is the difference between margins and indentation?

Answer 1

The margin is the boundary where text normally begins. From that point, if the text is moved to the right, it is indented. Sometimes, the beginning of a paragraph is indented in a letter or a book. This paragraph is an example of how the first line is indented and the rest of the lines of the paragraph begin at the left-hand margin. There is also a margin on the right-hand side of the page, not to mention the top and the bottom of the page also have margins. Indenting tends to highlight a line or an entire section of text may be indented to set it apart from the rest of the body of text.

Answer 2

A margin - is a fixed reference point on the page - creating a clean border around the text. Indentation - is an increased position, forward of the margin setting to emphasise (for example) bullet points in the text.
