Do you want to understand your camera and take great photos today?

Yes Please

At some point, you are going to want to resize, crop or modify the size of your image. Adobe Lightroom can resize an image, but you will need Adobe Photoshop to do it more professionally.

Read here for our tips on how to resize an image in Photoshop.

How to Resize an Image in Photoshop

Let’s start with the image you want to resize in Photoshop. Open Photoshop and click on open. Find your image in the navigation box and click open.

Your image will appear in its default state. This depends on the original dimensions of the image.

First, check the resolution and actual size of your image.

Click on Image in the top bar menu.

Continue to Image Size.

This box will give you all the information you need about the size of your image.

Change the resolution to 300. This is how many dots per inch (dpi) there are. This means your image has the highest quality from the start.

Under Image Size, you will see the initial size of the image, and the current size.

This has decreased due to changing the resolution from 72 to 300 dpi and the size from 168.31 cm to 30cm.

You can change the width and height as you see fit. You might prefer to resize in cm to print the image for a specific frame.

Working in pixels would be better for web. WordPress and websites tend to use images of 700 pixels at their longest edge.

The thing to note is resampling. If this box is checked, it will keep the initially set dimensions, and the same ratio of the image (usually 2:3).

Under the drop-down menu Dimensions, you can find preset sizes.

After clicking OK, your image will reappear in the usual interface.

If it’s too small, or you would like to continue to work on it, look towards the bottom left-hand corner.

The percentage size is the percentage of the actual size of the image you are seeing. In this case, the image is 4 times smaller than its actual size.

You can choose to zoom in, or click on the percentage to type a new value.

At the top, you will see Style and a subsequent drop-down menu.

Normal allows you choose the size.

Fixed Ratio keeps the predetermined ratio.

Fixed Size is a specific size.
