As our computer monitors get bigger, and our eyes get older, it can be hard to see things in your Excel files. Here are a couple of tips that I use, to make things easier.
1) Zoom In
To focus on a specific part of a big worksheet, select a range of cells. Then, on the View tab, click Zoom to Selection. When you’re done, click the 100% button.

2) Pick a Colour
When you’re choosing a custom colour in Excel, drag the bottom corner of the dialog box, to make it bigger.
Or, double-click the title bar, to fill the entire screen!
