Resize an Image Using Photoshop

By Halstatt Pires

Photoshop is a wonderful tool for graphic design, web development and any other form of digital media creation. In this article, we discuss resizing an image using the program.

Photoshop has many uses and is a very powerful program with many different capabilities and functions. Photoshop can have a high learning curve and may be a little overwhelming at first because of all the different tools and options available to use, but I am sure you thought the same thing about learning to read. Now look at you, you are a pro.

As with any thing in life practice is the key to becoming better at things you don’t know or think are too difficult. Try not to become intimidated and don’t be afraid to try new things and experiment. Someone famous once said that learning from failure is the key to success.

While Photoshop may be a lot more program than you need to resize an image, it is an important function to learn because it is a common technique in digital media development. Why would you want to resize an image in the first place? There are numerous reasons, but the most common is to make photos fit on web pages or print material.

Ok, as for the actual steps involved in resizing an image here they are:

1. Open Adobe Photoshop and the photo you wish to resize.

2. Once you have your photo open navigate your mouse to the tool bar that runs along the top of the screen and click on “Image”.

3. Once you click on “Image” from the tool bar, a drop down menu will appear. Select “Image Size” from the drop down menu. A window should popup with the images properties.

4. Initially, for our intents and purposes we only want to pay attention to “Pixel Dimensions” in the popup window. You will see that you can control the width and height values of the image in the popup window. You should also see a drop down menu for selecting “pixels” or “percent”. Make sure pixels is the unit selected in both the width and height fields. Pixels are tiny dots of color that make up the photo. If you ever look at printed material under a magnifying glass you will notice that the image is made up of tiny dots of color. These tiny dots of color are analogous to what pixels are in a digital image.

5. Okay. Let’s pretend that the image you opened up at the start of this tutorial is very large, something like 2000 pixels wide by 1500 pixels in height and we want to resize the image to fit on a web page. Most web pages are somewhere around 800 pixels wide by some arbitrary height. The reason height is arbitrary is because it is determined by how much content appears on the page. Let’s say that we want the image to take up about half the width of the web page. To accomplish this we would change the pixel width value from 2000 to 400 pixels (which is half of 800 pixels, the width of the web page). Make sure that the “Constrain Proportions” option is checked so that the ratio between width and height is preserved and the image does not become distorted.

6. Click “OK” and save the newly resized version of your image. YOU’RE DONE!

You just resized your first photo using Photoshop and are now 100 times more advanced. Congratulations you are on your way to becoming a Photoshop master.
