Resizing Images in Lightroom – Pretty Presets for Lightroom

Resizing in Lightroom

How to Resize an Image in Lightroom

If you are new to Lightroom (or not so new, as this took me a while to figure out), you may be a bit confused as to how you can resize images in Lightroom. For the longest time, I searched high and low for the resize option, but came up empty-handed! I was actually using Photoshop to resize, but once I figure out how to resize in Lightroom, I realized it’s a piece of cake!

You will find the resize option in your Export dialogue. So, go to your top toolbar, select File, Export, and you will see this box:

Once you see the above box, use the arrow on the right to scroll down until you see Image Sizing, then check the “Resize to Fit” box.

At this point, you will have several options for resizing, so let’s look at how they work:

Resizing Image: Width and Height

With all of the resizing options, you can choose your dimensions in either pixels, inches, or centimeters, as well as select your resolution. In the example below, I am using pixels with a measurement of 2048 X 2500. This is the quick, easy and custom way to set your pixels and resolution.

Resizing Image: Dimensions

As you can see below, I changed my dimensions to inches, and entered 8X10. This function isn’t to be confused with cropping in Lightroom. If you haven’t cropped your image in Lightroom previous to exporting using this method, Lightroom will resize the image as close as it can to the dimensions you entered but may not get it exact. Cropping your image to the 8×10 aspect ratio before exporting will ensure that the image fits those dimensions perfectly.

How to Change Resolution in Lightroom

Resizing Image: Long Edge and Short Edge

With this feature, you can choose to edit either the long or short edge of your image, and Lightroom will automatically adjust the rest of the dimensions for you. This is extremely handy if you are editing a photo for online sharing, as websites and blogs often require a specific pixel measurement on one edge of the image.

Image Resolution

Another important factor to keep in mind is resolution. If you are editing for the web, a resolution of 72 pixels per inch is more than enough for screen display, however, if you are going to make a large print, you will want a high resolution of 240-300 ppi.


If actual file size is a factor in your exporting, you can set your megapixels. This is a great option if you are not bound by specific dimensions, but rather, file size. This feature comes in hand for submitting images to competitions or if specific websites have a maximum file size allowed when uploading. This feature is also helpful if you are emailing your photos or simply do not want to use too much space on your blog or website.

Create Sizing Presets

Another useful trick in your Export dialogue is the ability to create presets for your commonly used dimensions. To create your own sizing preset, first set the export settings exactly how you would like them in the Export dialogue box. Then in the Export dialogue, select Add (lower-left side of box, above the Plug-in Manager button).

Once you have named your preset, click Create. In the future, you will find your preset under the User Presets options on the left side of the dialog box and be able to quickly apply the same settings to your images.

Resize Without Overwriting the Original

As you probably know, one of the greatest benefits of Lightroom is its non-destructive editing. So, you can resize your images in Lightroom, without having to worry about accidentally overwriting your original image with a smaller version. Many times I have accidentally overwritten my original edit with a smaller version in Photoshop, destroying the original forever.

Lightroom does not overwrite the original when you resize. It is possible to do, but you really have to go out of your way to tell it to overwrite the file. If a file is about to be overwritten, Lightroom will ask you if you want to overwrite the original file, or use unique names. Always select “Use Unique Name” just to be on the safe side.
