To change the width of an image in Photoshop without affecting the height, follow these steps:
-
Open your image: In Photoshop, go to File > Open and select the image you want to edit.
-
Access the Image Size dialog box: Go to Image > Image Size. This will open a window where you can adjust the dimensions of your image.
-
Adjust the width: In the "Image Size" dialog box, you'll see fields for Width and Height.
- Ensure Resample is checked: Make sure the "Resample" box is checked if you want Photoshop to add or remove pixels to achieve the new width. If it's unchecked, changing the width will crop the image. The resampling method will determine the quality of the result. "Bicubic Automatic" is often a good choice. Other options like "Bicubic Smoother" or "Bicubic Sharper" can be used if you are enlarging or shrinking the image respectively.
- Unlink Width and Height (if linked): Look for a chain icon between the Width and Height fields. If this is linked (icon displayed), clicking on the icon will unlink the width and height. This will let you alter the width independently. If unlinked and both are changed, the aspect ratio will be changed.
- Enter the new width: Type in your desired width in the "Width" field. Make sure the units (e.g., pixels, inches, centimeters) are correct.
-
Confirm Your Changes: Click "OK" to apply the new width to your image.
Now, your image will have the adjusted width while the height remains unchanged, and Photoshop will have resampled (if resampling is selected) the image content to fit the new dimensions. If resampling is not used, then the edges will be cropped.
