Change the canvas size
The canvas size is the full editable area of an image. The Canvas Size command lets you increase or decrease an image’s
canvas size. Increasing the canvas size adds space around an existing image. Decreasing an image’s canvas size crops
into the image. If
you increase the canvas size of an image with a transparent background, the added canvas is
transparent. If the image doesn’t have a transparent background, there are several options for determining the color
of the added canvas.
1 Choose Image > Canvas Size.
2 Do one of the following:
• Enter the dimensions for the canvas in the Width and Height boxes. Choose the units of measurement you want
from the pop-up menus next to the Width and Height boxes.
• Select Relative, and enter the amount you want to add or subtract from the image’s current canvas size. Enter a
positive number to add to the canvas, and enter a negative number to subtract from the canvas.
3 For Anchor, click a square to indicate where to position the existing image on the new canvas.
