Though printing a picture that will fit a standard-sized picture frame, such as an 20 x 25 cm (8 x 10 inch) or 12.5 x 17.5 cm (5 x 7 inch) frame, is extremely easy, creating a photograph that will fit an odd-sized frame is also relatively easy. PC users can create and print a custom-sized image by using Microsoft Paint. The application is preinstalled on many Windows platforms, such as XP, Vista, Windows 7 and Windows 8, and it's easy to use.
Measure the height and width of your picture frame, and write the proportions down on a piece of paper. For accurate results, use a ruler or tape measure.
Go to "Start" and click on "All Programs." Click on "Accessories" and open "Paint." When you open the application, a white canvas will appear on the screen.
Click on the "File" tab and select "Open." Locate the image you want to resize and click "Open."
Click on the "Resize" button, which is located in the "Image" section on the toolbar. The "Resize and Skew" dialogue box will appear on the screen. You will notice that the box next to "Maintain aspect ratio" is checked. Leave the box checked.
Click "Pixels" and enter the width of your photograph in the "Horizontal" field or the height in the "Vertical" field. Depending on which field you enter first, the second field will update automatically due to the "Maintain aspect ratio" option. When you're finished entering the proportions, click "OK."
Click on the "File" tab and select "Print."
Depending on the size of your frame, you may need to remove the check next to the "Maintain aspect ratio" option to enter exact measurements for the height and width.
