Margins define where the text line starts and ends. It is the empty portion around the page in a document. It separates the content from the edge of the page.

Margins are an integral part of the document. In the absence of margins, the text will occupy the whole page, which looks unappealing to the viewers. Most users prefer the default margin, but there are times when you may want to change the margin for the whole document or a selected portion.

There are two ways to modify the default margins. You can either do it using the ruler on the top and edge of the page or through the File menu.

### Using Ruler

There are rulers at the top and side of the page. You will find the margin line markings on the ruler. The margin line marking is hidden, and you can only see the marking when you move the cursor over it.

The default margin in Google Docs is 1 inch or 2.54 cm.

To adjust the margin, hold and drag the margin line marking to either side, and the text will move accordingly. For instance, you want to move the left margin further to the left. Just hold and drag the marking to the left and release when it has shifted the required amount.

The left margin that was 1 inch by default has now changed to 0.5 inches.

You can similarly change the top and bottom margins. The bottom margin is adjusted from the bottom of the page. You will, therefore, have to scroll to the bottom.
