Besides reading the measurements in the Margins page of the Page Layout dialog, the best way is to look at the horizontal and vertical rulers. On the horizontal ruler, the left and right margin areas are shaded in gray. The markers, which usually coincide with the edges of the margins, indicate the left and right indents of the current paragraph.
The vertical ruler shows shading for the top and bottom margins.
Also, there are two options to display where the margins are. Most people keep them turned off most of the time because they're distracting.
One method is to go to File > Options > Advanced, scroll down to the "Show document content" section, and check the box for "Show text boundaries".
This option places a thin gray box around every paragraph in the document:
The margins are just the areas outside the boxes.
The second option is immediately below the "text boundaries" option, "Show crop marks". This places a right-angle mark in each corner of the page, with the horizontal and vertical lines indicating the edges of the text area.
Again, the margins are the areas outside the crop marks.
