When you want to change the size of your canvas in order to increase the available space for drawing or to crop the canvas down, you can edit the canvas size. Editing the canvas will not change the pixels of your artwork, other than removing data if you are cropping to a smaller size.

The maximum canvas size is 100 megapixels. If you change a dimension to a number that would cause the canvas to exceed 100 megapixels, you will see an error message and be unable to apply the change.

If you want to change the size of your artwork, for example changing the image's resolution, you will need to edit Image Size.

Crop the canvas to a selection

If you want to reduce the size of your canvas, you can crop it by creating a selection and then using the crop tool in the selection toolbar.  

This will crop the entire canvas (all layers) to the selection. Regardless of the type of selection, the cropped canvas will be a rectangle. Keep in mind that this action will also reduce the number of pixels in your canvas, there is no resampling when cropping to a selection.
