Resize an image in Photoshop



Adobe Photoshop logo

Is your image too big or too small to fit your needs? With Adobe Photoshop on Mac or Windows, it’s easy to quickly and accurately resize a photo. Here’s how to do it.

To get started, open Photoshop on Mac or Windows PC and load the image you want to resize. In the Photoshop menu bar, click “Image”

; and then select “Image Size” from the menu that appears.

Select Image Size” in the Photoshop menu bar.” width=”650″ height=”319″ onload=”pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);” onerror=”this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);”/>

In the “Image Size” window, you must first decide which unit of measurement you want to use to resize the image. If you click the drop-down menu next to the “Width” or “Height” fields, you can choose the unit type. Here’s what each choice means:

  • per cent: Allows you to resize by a percentage of the current image size. For example, if you use 50% as the target image size, the image will be half the current size. Likewise, 200% makes it twice as big.
  • Pixel: Allows you to specify exact pixel dimensions for the resulting image size.
  • Inches, Centimeters, Millimeters: These are standard measurement sizes that only apply when an image is printed, and they are related to the DPI of the image.
  • Points: A point is a unit of measurement common in typography that corresponds to 1/72 of an inch. In a 72 DPI image, one dot equals one pixel.
  • Pics: One pica equals 1/6 inch or 12 points and is most commonly used in design for printing.
  • columns: Allows you to resize by number of columns, any unit defined in Preferences > Units & Rulers.

Many people use “Percentage” to notice changes in relative size, but if you’re resizing images for the web, you’ll probably want to pick “Pixels” from the list.

Select a unit of measure on the

Then decide whether you want to keep the aspect ratio of the original image. The aspect ratio is the proportional relationship between the two sides of the image (width and height).

If you choose to keep the original aspect ratio of the image, you only need to change the value of “Width” or “Height” for your image. Photoshop will automatically change the value of the other field based on the existing ratio.

In general, you should keep the aspect ratio so that your photo doesn’t look weird. But if you want to disable it, click the chain icon between “Width” and “Height” so that the small lines pointing to “Width” and “Height” disappear.

Keep or discard the aspect ratio on the

Now comes the part where you resize your photo. To change the width of your photo, click the “Width” field and enter a new size. Likewise, to change the height of the photo, click on the “Height” field and enter a value.

Then click “OK” at the bottom of the “Image Size” window.

The resized version of your photo will now appear on your screen. If this is okay with you, click File > Save in the Photoshop menu bar to save the photo.

To save the resized photo as a copy (so that your original photo is not affected), click File > Save As from the menu bar.

Select Save As” in the Photoshop window.” width=”650″ height=”403″ onload=”pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);” onerror=”this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);”/>

If you chose “Save As”, you should now see the Photoshop save window on your screen. Enter a name for your photo at the top of this window, then select an image format from the “Format” drop-down menu and click “Save” at the bottom.

That is it! Your photo is now exactly the size you wanted and you can use it anywhere it didn’t fit before.
