How to resize an image to match another in Photoshop

This tutorial shows you how to instantly match the size (width and height) of two images or documents open to Photoshop using the Image Size dialog box and the Window menu. For Photoshop CC, CS6, and earlier.

If you're composing images, designing a design, or posting photos on the web, you often have to resize images in Photoshop so that they share the same dimensions (the same width and height). One way to do this would be to manually enter the same values for width and height in the Photoshop Image Size dialog box for each image that needs to be resized. But if one of your images is already the size you need, here's a trick that will allow you to save time to resize another image to match. I will use Photoshop CC 2018 But any recent version will work.

Two images, two different sizes

Here I have two images open to Photoshop. This first image is the larger of the two and the one I need to resize (Portrait photo

To see the current size of the image, I will upload the file Image in the menu bar and select Image size:

Open the Image Size dialog box to Photoshop

Opens the Image Size dialog box.

In the Image Size dialog box, we see that this image has a width of 5184 pixels already height of 3456 pixels. Click Cancel Now to close the dialog box without making any changes:

The Image Size dialog box displays the current width and height of the larger image.

To switch to my second image, I'll click on the document tab. Note in the tabs that my largest image is called "large portrait" and my smaller image "small portrait". The names of the images will be important when we resize to match the size of the other:

Click the tab to view the second image.

After clicking on the tab, we see my second smaller image (Portrait photo

The view of its size, I will go back up to the Image menu and select Image size. And here we see that this smaller image has a width of 1600 pixels already height of 1067 pixels. I need to resize my larger image to match this exact measurement, but you don't have to write the numbers. Instead, let's see how Photohop can enter the values for us. I'll click Cancel again to close the dialog box:

The second image is already set to the width and height we need.

How to resize one image to match the size of another

Step 1: Select the image to resize

To resize an image to match the size of another open image, first select the document containing the image to change by clicking the tab. I will select my "great portrait" document:

Choose the image to resize to match the other image

Selecting the image to resize.

Step 2: Open the Image Size dialog box

With the document selected, navigate to the Image menu and select Image size:

Choose the Image Size order from Photoshop's Image menu

Ir a Imagen> Tamaño de la imagen.

The Image Size dialog box opens where we see the current width and height of the image. As a quick update, again we see that my largest image is 5184 pixels wide and 3456 pixels high:

Current width and height of the larger image

The current width and height of the image.

Step 3: Choose the image you want to match from the window menu

To resize the image to match the size of another image, go to window in the menu bar. At the bottom of the window menu is the name of each image currently opened in Photoshop. In my case, I have two open images, "portrait-large.psd" and "portrait-small.psd". The image you are currently viewing has a check mark attached to it. Choose the image you want to match. I will choose "portrait-small":

Select the image with the size you want to match in the Photoshop Window menu

Select the image with the desired size from the Window menu.

Photoshop instantly changes the width and height values to match the dimensions of the image you selected. In my case, the larger image will now share width (1600 pixels) and height (1,067 pixels) than the smaller image. Click OK to resize the image. The two images are now the same size:
