To make an image fit to the screen in Photoshop, you primarily adjust the image size using the Image Size dialog box. Here's how:
Resizing Your Image
-
Select the Image: Open the image you wish to resize in Photoshop.
-
Access Image Size Dialog: Go to the main menu bar and select Image > Image Size. This will open the Image Size dialog box, which provides all the necessary controls to adjust the dimensions of your image.
-
Adjust Image Dimensions: In the Image Size dialog box, you have several options for resizing your image.
- Fit To Drop-Down Menu: The "Fit To" drop-down menu offers several pre-set sizes for common web and print resolutions. Choose one of these options if it suits your needs.
- Width and Height Fields: Manually enter the desired Width and Height values in pixels, inches, or other measurement units. This provides the most precise control over the resizing process.
- Keep Proportions: Make sure the "Constrain Proportions" icon (usually a chain link) is activated to avoid distorting your image. This option maintains the original aspect ratio of your image.
- Resampling Options: Explore the resampling methods available to achieve a more optimized resizing process. For instance, the Bicubic Sharper option is suitable for reducing the size, while Bicubic Smoother is better for enlarging the image. The default Bicubic option is best for general usage.
-
Confirm Changes: Once you’ve made your adjustments, click "OK" to apply the resizing.
Practical Insights
- Resolution: Be mindful of the resolution settings. Web images generally require 72 ppi (pixels per inch) whereas print images typically use 300 ppi.
- Image Quality: Always try to work with a high-quality original image to reduce pixelation or loss of details when resizing.
- Non-Destructive Workflow: Use smart objects and adjustment layers to make size and other edits non-destructively, enabling you to modify changes without permanently altering the original image data.
- Viewing Modes: Use the zoom tools (magnifying glass icon or by pressing Ctrl + Plus/Minus or Cmd + Plus/Minus ) and Hand tool (press the space bar) to observe how the image fits on screen in various zoom levels without changing its actual size.
Example
Let’s say you have an image that is 2000 x 1500 pixels and you want it to fit the screen of a monitor with a resolution of 1920x1080 pixels. You could:
- Enter 1920 for the width while making sure the constrain proportions link is on. The height will then adjust automatically to 1440 and you can crop if needed.
- Use the fit to options in the "Fit To" drop down menu. There are preset options such as a 1920 x 1080.
By using the options in Image Size dialog box, you can ensure your image fits the screen perfectly for the purpose you intend, whether it's for web display or print.
