Aspect Ratio Calculator

This aspect ratio calculator (also, very handily, a screen size calculator) will answer all of your questions regarding what is aspect ratio and how to use it. In brief, aspect ratio and screen size are two very essential, quick and comfortable measures used when you want to resize your images or videos for the purpose of adapting them to the requirements of your project.

Aspect ratio is a proportional relationship between the width and height of an image. It is usually described with two numbers and a semicolon between them, for example, 2:1. This means that the width of the image is twice its height. It's a very useful device for resizing photos or videos for your blog or social media account.

Applying the aspect ratio calculator is very easy. You need to divide the original height by the original width and then multiply this number by the new width to get the new height. These steps will give you the correct height for your edited image.

• Take your original height. In our example, it will be 1200 pixs
• Take your original width. Our image has a width of 1600 pixs
• Divide the height by the width, e.g. 1200 / 1600 = 0.75
• Multiply the quotient by the preferred width, e.g. 0.75 * 300 = 225
• The resulting figure is your new height given in pixels.

Screen size detects the physical dimensions of your display in inches and indicates the number of pixels that can be displayed on the screen of your computer. It's essential for all you webmasters out there to be able to calculate screen size. In order to do that, you can either calculate it on your own or use our calculator. Read the next section to learn how.

The very first thing you need to do when calculating screen size is to chose your aspect ratio. Then, you will have to measure any of these three measurements: diagonal length, width or height. It is enough to simply give one of them and the rest will be calculated automatically in centimeters or in inches.

• Set up you aspect ratio
• Give one of the measures: height, width or dimensional
• Choose your preferred units: centimeters or inches
