How to Resize Images in Photoshop

Written by Emma Hackett

Whether you're a seasoned designer or a photography enthusiast, resizing images is a vital skill for various projects. In this guide, I'll walk you through the best practices, from opening your image to selecting the right dimensions and resolution. Learn the art of preserving image quality and aspect ratio effortlessly with these easy-to-follow instructions.
How to Resize Images in Photoshop

Step 1: Open Your Image

Launch Adobe Photoshop and open the image you want to resize. Go to the “File” menu and select “Open,” then navigate to the image file on your computer and click “Open.”

Step 2: Duplicate the Image (Optional)

Before resizing, it’s always a good idea to create a duplicate of the original image, so you can preserve the original size in case you need it later. To do this, go to the “Layer” menu and choose “Duplicate Layer.” Click “OK” in the dialog box to create a duplicate layer.

Step 3: Select the Image Size

To resize your image, go to the “Image” menu and select “Image Size.” A dialog box will appear, displaying the current dimensions of your image.

Step 4: Set the New Dimensions

In the “Image Size” dialog box, you can specify the new dimensions for your image. You have several options to control the size:

  • Width and Height: Enter the desired width and height in pixels, inches, centimetres, or other units. Make sure the “Constrain Proportions” box is checked to maintain the original aspect ratio.
  • Resolution: This refers to the number of pixels per inch (PPI) and is essential for print projects. For web and screen use, you can ignore the resolution and focus on width and height.

Step 5: Choose Resampling Method

Photoshop offers several resampling methods to adjust image size. For most cases, “Automatic” or “Bicubic” interpolation works well. “Automatic” is recommended for reducing size, while “Bicubic Smoother” is better for enlarging images. Avoid “Resample” for now, as it may lead to loss of image quality.

Step 6: Preview and Adjust

As you make changes in the “Image Size” dialog box, the preview of the resized image will be displayed. Pay attention to the “Document Size” section to see the final dimensions and resolution. If you’re satisfied with the changes, click “OK” to apply the resizing.

Step 7: Save Your Resized Image

After resizing, save your image using “File” > “Save As” and choose a new name to distinguish it from the original. If you’re working on a layered image and want to preserve layers, save it as a PSD file. For web use or sharing, save it as a JPEG or PNG file.

Some final tips!

  • Always work on a duplicate layer to preserve the original image.
  • Keep the “Constrain Proportions” box checked to avoid stretching or squashing the image.
  • For print projects, ensure you have a suitable resolution (usually 300 PPI).
  • Avoid resizing images multiple times, as it can lead to loss of quality.

That’s it! You’ve learned the best way to resize images in Photoshop. With this skill, you can confidently adjust image sizes for various purposes, whether it’s for web, social media, or print projects. Happy editing!
