Changing Poster Dimensions On Zazzle.com

Changing your poster's dimensions on zazzle.com is a simple and straightforward process:

1. Navigate to the zazzle.com product webpage for whatever poster you want to customize.
2. Click the orange "Customize It!" button below the poster image.
3. Click the link that reads "Choose your size and frame."
4. Under "Size it up or down," select your closest target size using the radio buttons.
   
   
5. To adjust the height and/or width, under "Choose your print size," select your desired unit (inches, centimeters, or pixels) using the pulldown menu.
6. Enter your desired dimensions. To keep the original aspect ratio, leave the "Link these" box checked and enter your desired height or width; to change both the height and width to your specifications, de-select "Link these" before entering your new figures. Note that by de-selecting "Link these," the poster image will be cropped to accomodate the new aspect ratio.
7. Press "OK" to finalize the changes.
8. If you don't like whatever changes you made and want to start fresh, click "Revert" at the bottom of the menus and press "OK" in the popup window (or hit your browser's "Refresh" button and start again from Step 3 above).
