If you find that your screenshot is too big, follow the instructions below to change the size.

To resize your screenshot in Paint

1. On the Image menu, click Stretch/Skew
2. Type the percentage of the current size that you want (e.g. 50%) in both the Horizontal and the Vertical box
3. If the size is still not what you want, click Edit>Undo and then repeat steps 1 and 2 until you get it the size you want.

To crop your screenshot in Paint

1. On the Image menu, click Attributes.
2. Under Units, click the unit of measurement you want to use for the width and height (inches, centimetres or pixels)
3. Type the measurements in Width and Height.

You can also crop your picture by dragging the image resize handles, located at the lower-right corner and along the bottom and right sides of your picture.

You might need to maximize the window to see the square resize handles. They are a tiny blue box in the very bottom right corner. You'll know you've got them when your cursor turns into a double-ended arrow.

If your current picture is bigger than the new size, the picture is cut from the right side and bottom to fit within the smaller area. If your current picture is smaller than the new size, the extra area is filled with the selected background color.

Or you can use ResizeYourImage.com

ResizeYourImage.com is a free tool that allows you to crop or resize your photos in just a few easy steps.

The site works very simply. You just upload your image in any format (e.g. gif, jpeg, tiff), and then use the buttons on the site to crop, enlarge or decrease it.

When you have the image just the way you want it, press a button, save it back to your computer, and it’s ready to use.

So if it's a screenshot that you want to resize:

1. follow the instructions for making a screenshot
2. save it to your computer
3. go to ResizeYourImage.com
4. upload your image
5. make your changes
6. save the revised image to your computer

(This method works for any image, not just screenshots.)

By the way, you don't have to buy any special software to make screenshots. Your computer already has the cabability to do it quickly and easily. I have instructions here on how to make a basic screenshot.
