To change the size of a canvas in a digital art program, you can follow these steps:

1. Open the program and create a new canvas or open an existing project.
2. Look for the option to resize the canvas. This can usually be found in the 'Image' or 'Canvas' menu at the top of the screen.
3. Click on the resize option and a dialog box will appear where you can input the new dimensions for the canvas. You can change the width and height in pixels or other units of measurement.
4. Once you have entered the new dimensions, click 'OK' or 'Apply' to resize the canvas.
5. Your canvas should now be resized to the new dimensions you specified.

If you are working with a physical canvas for traditional art, you can use a ruler and pencil to mark the new dimensions and then cut the canvas to the desired size. Alternatively, you can purchase a canvas in the size you need.
