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

1. Select Image > Canvas Size.

   The Canvas Size window appears. It shows the current pixel size and memory size in the top panel.

   For PC

   For Mac

2. Type in the new sizes for the canvas.
   NoteTyping larger values increase your room for sketching. Typing smaller values crops the existing image.

   The default units are pixels, but you can change them to inches, cm, or mm. Or, specify a percentage change.

   The Memory field updates to reflect the memory size required for the new size.

3. Click the Anchor interface to specify how to resize the canvas. For example:

   | Expands equally from every edge.
   | Expands up and to the right.
   | Expands up, down, and to the left.

4. Click OK or press the Enter key.

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

1. Select Image > Image Size to use the Image Size window.
2. Check Keep proportions on.

   For PC

   For Mac

3. In either the Pixel Dimensions or the Document Size section, change the pull-down units to percent.

   For PC

   For Mac

4. Type in a new value.

   For example, type “200” to double the image size, or “50” to half the image size.

   All other values update automatically, including the memory size.

5. Click OK or press the Enter key.

   For PC

   For Mac

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)

1. Select Image > Image Size to use the Image Size window.
2. In the Document Size section, leave the pull-down units at inches (or cm or mm).

   For PC

   For Mac

3. Type in a new value in the Resolution field.

   For PC

   For Mac

   The document size stays the same, but the new resolution value changes the pixel size (and the memory size).

4. Click OK or press the Enter key.

   For PC

   For Mac

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.

Changing document size (and keeping pixel size the same)

1. Select Image > Image Size to use the Image Size window.
2. Check Keep proportions on.

   For PC

   For Mac

3. In the Document Size section, change the pull-down units to percent.

   Keep the height and width at 100 percent.

   For PC

   For Mac

4. Specify a new value in the Resolution field.

   For PC

   For Mac

   The image size (and the memory size) stays the same, but the new resolution value changes the document size.

5. Click OK or press the Enter key.

Fitting a resized image onto the screen

Flick toward this icon or:

- for Mac press Cmd+0
- for PC press Ctrl+0 (zero)

to expand the image or reduce it to fill the screen.

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.
