Resizing
 
 
 

Change the size of the canvas, image, or document.

Resize the canvas

Make more room for sketching by increasing the canvas size.

Resizing the canvas

Resize the image

Change the size of the image, its resolution, or the document size.

Image size is the size of the image in pixels.

This size directly affects the memory size in a squared relationship, quadrupling the memory size if you double the pixel size. Increasing the image size four times increases the memory size 16 times. Because of memory requirements, there is a 6400x6400-pixel upper limit on image size.

Changing image size by a percentage

Change the resolution

Resolution is the number of pixels per inch or per cm. Leaving the document size the same increases the quality of the image and resolution; however, the memory size also increases.

To change the resolution (and keep the document size the same):

Changing resolution (and keeping document size the same)

Change the document size

The document size is the size of the image in inches, mm, or cm. Images saved out from Autodesk SketchBook Pro print out at that size in Adobe® Photoshop® or other publishing programs.

Image Size window settings

In the Image Size window, all values update concurrently as you enter new values.

Pixel Dimensions

The top section of the window shows the pixel dimensions of the image.

For PC

For Mac

The drop-down menus let you change the dimensions using a percentage instead of pixels. This section also shows the memory size of the image in MB (this size updates automatically whenever you resize the image).

Document Size

The bottom section of the window lets you set the document size.

For PC

For Mac

The default units are inches, but you can change them to cm, mm, pixels, or percent. In this section, you can also set the print resolution in either pixels/inch (ppi), pixels/cm, or pixels/mm.

Keep proportions

This setting is selected by default, to prevent image distortion. De-select it to change one dimension only, leaving the other dimension unchanged.
