How to Precisely Capture Screens on Windows With Sizer

Capturing screenshots can be a pain. This is especially the case when you require the screenshot to be of a certain size/resolution. You try to resize the window in question as best as you can but it doesn’t always quite work out and you may have to rely on additional software to resize the screenshot after you take it.

How it Works

Sizer is a well thought out utility that makes it easy for users to precisely resize program windows as they wish.

Sizer Configuration

Your first step while using this app should be to configure the window sizes you wish to work with. The above screenshot is pretty self-explanatory but you should note the following points.

Firstly, you can set the position you would like the window to be moved to after resizing. You can also choose not to move the window after resizing.

Take note of the User Defined Position option. Users can enter their own coordinates for where they would like the window to be moved, where Top = 0 refers to the very top of the screen and Left = 0 is the leftmost part of the screen.

Lastly, Window resizing snap size defines the number of pixels by which the size of the window is increased/decreased when resizing it and simultaneously holding the Ctrl key.

There are three ways to activate Sizer. You can right-click on the title bar of the program window in question, or you can choose to click on the program icon — if there is one —  in the top left of the program’s title bar.

You can also resize a window by right clicking when the resize cursor becomes visible.

Note that you can also right click when you have moved your mouse to the appropriate position for the resizing cursor to appear in order to bring up the context menu which will allow you to precisely resize the window in question.

Finally, you can resize windows directly from the system tray by right-clicking on the Sizer icon and selecting the appropriate option. In order for this to work, however, you will need to set Sizer to always show in the system tray.

Even if you choose note to use one of your preset options, there is an interactive tooltip that pops up if you choose to resize manually which will let you know exactly the size that you changed the size of the window to. This pops up as long as Sizer is open.
