The eye perceives when things are out of balance, even if the brain cannot identify the cause of it. This is even more evident when the slides are projected on a large screen. Take these images for example:
First, let’s look at how I made these elements. Each consists of two PPT autoshapes, a rounded corner box and a text box with a semi-transparent fill.
So what’s wrong with them? The left box’s text box is a few pixels lower than the others. The right rounded corner box is a few pixels higher than the others.
To fine tune this set of objects I would first select the 3 text boxes and use the ALIGN MIDDLE tool to have them all vertically line up – to the pixel. I would then do the same thing by selecting the 3 rounded corner boxes.
The end result is something that is in balance – and your eyes know it (or at least do not focus on it).
