A Ruler

If you need to measure the dimensions of anything on your screen, A Ruler is an ideal tool to help you out, since it will display a traditional ruler that will allow you to obtain the size of any image, text box, or other determined area of the screen.

When using A Ruler, keep in mind that the unit of measurement employed by the program is the pixel, and it doesn't measure in inches or centimeters. A red bar on the ruler will help you to check the exact measurement of any element.

A Ruler is available in two materials: wood and plastic. Use the plastic if you want the ruler to be transparent so you can see what's behind it.

You can also choose the ruler's orientation, including the position of the measurement guides and its general size.
