In FTM 2014, in the Tools Menu, you can choose Options and set the font size to 'Use large fonts"
Within some of the screens, you can adjust the various sections of the screen to open up more or less space. You move those section dividers with your mouse.
You can also close down the Name Index section at the left to give more space to the rest of the screen. To do that, click on the little shaded box above the home button. To restore it, click on that shaded box again.
You can adjust your overall Windows font size to use a larger font. I have 2 large high-res monitors and set my Windows font size to 125% to make things easier to read.
To change all fonts in Windows 7 from your desktop, right-click anywhere on an empty place, then select Display in the lower left corner of the screen.
