Change the Canvas Size in Windows 7 Paint

By default, new documents in Windows Paint have a canvas size of about 800×400 pixels, but you can changes this through the Properties menu. Here’s how to change the canvas size in Paint through the “Ribbon” UI introduced to this application in Windows 7:

1. Pull down the file menu from the dark blue button on the top left, next to Home.
2. Click Properties to bring up the Image Properties window.
3. Change the Width and Height boxes to your desired canvas size.
4. Press the OK button.

Going forward, new Microsoft Paint documents will use the size you’ve set in the Image Properties window. If you want to change it again, just repeat this procedure.

If you want to reset your options to Paint’s default size, press the Default button.
