what is the default margin size in a word document

The default margin size in a Word document is 1 inch on each side of the page. This means that the top, bottom, left, and right margins are all set to 1 inch when you open a new document in Microsoft Word. However, you can customize or change the default margin settings by clicking on the "Margins" option in the "Page Layout" tab and then selecting "Custom Margins" to set your own margin size. Keep in mind that most printers require a minimum width for margin settings, and if you try to set margins that are too narrow, Word will display a message prompting you to increase the margin width.
