Canvas Size
The Canvas Size is the total area that your project can occupy. It is analogous to the Canvas
for a painting. The image has to appear somewhere inside the Canvas space.
When you open an Image File , or create a New File , Photoshop will create a Canvas Size
that is equal to the Background Layer . To enlarge the size of the Canvas , select Canvas
Size from the Image drop-down menu. To decrease the size of the Canvas , use the Crop
Tool .
The Canvas Size can never be smaller than the Image Size , but it can be larger than the
Image Size .
Increasing the Canvas Size is an easy way to add a border to your image. The change to the
size of the Canvas can be stated as a Relative Value or Absolute Value .
For borders, it is usually easiest to check the “ Relative ” box in the Canvas Size Window ,
and enter a value for Width and Height. These values will be added to the width and height
of the image as a border . If the “ Relative ” box is not checked, the dimensions that you
enter will be the Absolute dimensions of the Canvas .
When you select Image > Canvas Size , you will see the Anchor Grid within the Canvas
Size Window .
The image below shows what happens when you click on one of the arrows in the grid.
