How Do I Adjust the Image Size on My Computer?


Adjusting the image size or screen resolution on your computer is quick and easy. When you select a higher display resolution, the number of pixels per image increases and makes every image appear sharper on-screen. Depending on the operating system you are using, the steps will vary slightly, but the process is generally the same.

Using Windows XP

  • Right-click on an empty space on your desktop.

  • Select "Properties" from the drop-down menu. The "Display Properties" window opens.

  • Click on the "Settings" tab. Click and drag the "Screen Resolution" slider left or right and select the desired size. This ranges from 800 x 600 pixels, to 1600 x 1200 pixels.
    Click "Apply" to preview the selected image size (resolution).

    A dialog box displays "Your desktop has been reconfigured. Do you want to keep these settings?"

  • Click "Yes" in the above dialog box if you wish to keep the selected image size or "No" if you want to change it. Click "OK" to confirm.

Using Windows Vista

Using Mac OS X

  • Click on the Apple icon on the top-left corner of your screen, and select "System Preferences..." from the drop-down menu.

  • Click on the "Displays" icon, under the Hardware section. The "Display" tab is selected, and the current Image Resolution is highlighted under the "Resolutions" menu.

  • Select any of the available image resolutions under the "Resolutions" options, which go from "640 x 480" to "1440 x 900." As you click each, the selected image size displays and is automatically set. Continue clicking on the option that fits your needs.
