Sizer 4.0

Sizer lets you resize any window to a predefined size with just one mouse click

Sizer is a tiny utility that lets you quickly resize any window to a predefined dimension with just one mouse click.
This application is very small and simple. It just adds a context menu to any window. Right-clicking the border of that window will pop up the Sizer menu. This menu displays the preset sizes, letting you quickly resize that window to any of these dimensions. Sizer also adds a simple, unobtrusive tray icon from where you can access its options. I like that it also lets you automatically snap the resized window to a specific place on the desktop, such as to the right bottom or to the upper left side. You can also add your own preset sizes and positions.

Sizer is useful for a lot of purposes and in many circumstances, such as for taking screenshots of windows of the same sizes, which is handy especially when creating documentation materials and tutorials.

Last but not least, this simple yet handy tool is also free. As you can see, there’s no reason to stop you from installing it, too.
