Work out new aspect ratio for images (aspect ratio calculator)

This is a short post that will show you a great, and free, online tool to help you work out how to re-size an image without breaking the aspect ratio. This is a useful tool for when you want to change the size of an image to make it fit a specific space on your blog or website and don’t want to distort the image, or the video.

I have a number of sites where I find that I need to use stock images or other freely available images on the internet to illustrate an article or a post. One of the common headaches that I have with this occurs when I want to resize an image. This isn’t usually an issue if you have some image editing software on your computer that allows you to resize while preserving the aspect ratio of the image….. but what if you don’t, or if you want to scale up the perfect video that you have to illustrate a post, or you only have one length (height or width) defined and you want to calculate the missing value for a particular aspect ratio?

This tool Aspect Ratio Calculator provides a simple solution to this issue.

It is a simple form where you can enter the width and height values for your original image, and then simply type in either the length or height that you want to convert the image or video to, and the form will give you the new values.

To break it down further, lets say that you have an image that is 1600 x 1200 pixels, and you want to decrease the size of the image to fit into a space that is only 600 pixels wide – simply go to the tool above and enter your original dimensions on the left hand side. Then you would type in 600 in the width section on the right hand side, and the form would then automatically calculate that you image would need to be 450 pixels in height, in order to preserve the aspect ratio of the image.
