How to Scale Without Distortion in Photoshop

By Kirk Bennet

Adobe Photoshop enables you to create complex graphics as well as professionally edit photos. If you need your images to have a specific size, Adobe Photoshop is able to scale them for you. However, if you modify only one of the attributes (height or width), your image is distorted. Manually calculating the value of the second attribute every time you scale your images is time consuming. Photoshop can scale without distortion by adjusting the second attribute automatically.

Launch Adobe Photoshop and open the image that you want to scale. If the image is in a layer in your project, select the layer.

Click "Image" and select "Image Size" from the menu. Alternatively, you can press "Alt-Ctrl-I" to open the Image Size window.

Select the "Constrain Proportions" option to scale the image without distorting it and change the value in the "Height" or "Width" box. The second value changes automatically to prevent the image from distorting.

Click "OK" to scale the image and press "Ctrl-S" to save the changes.


A small chain icon appears between the Width and Height boxes when the Constrain Proportions option is enabled.
