The free tool Grid Move places an icon in the system tray after installation, a right-click opens a menu with the options and predefined templates such as desktops that are separated in two, three or four even grids. You would then do the following to place the windows in the grids. Left-Click the upper-left edge of the title of the window and grid mode should be automatically enabled. Holding down the left mouse button lets you move the window into one of the available grids and the window will be automatically resized to fit the grid.

If you are not satisfied with the default templates you may choose to create your own templates which might not be necessary for most users but great for certain applications that use custom window sizes. The help files provides enough information to create your own custom grids, I did not take a closer look at this option because I’m happy with the default templates.

You may enter grid mode using two different methods as well. The first uses the middle-button of the mouse. If you click a title with the middle-button it will automatically enable grid mode. Drag the window to the edge of the screen and keep it there for a while. This will enable grid mode as well.

Grid Move is a nice windows management tool which makes working with windows easier.
