Zooming in your documents in Adobe InDesign is a snap.
First, click the “View” tab in the toolbar at the top to open the view options. Then, click the “Zoom In” button. This will zoom in the document at the percentage indicated. Alternatively, you can click the slider in the Zoom control and drag it to the right or type in a new zoom percentage.
You can also use a mouse wheel to quickly and easily zoom in or out. Position your mouse pointer over the document you want to zoom, then scroll the wheel toward you to zoom in, or away from you to zoom out. You can also hold down the [Ctrl] key while scrolling to zoom in or out.
I hope this was helpful.
