This Aspect Ratio Calculator provides the calculated amount based on the desired aspect ratio. Add your own aspect ratio or adjust the width and height fields to start calculating.

One of the traditional aspect ratios is 4:3 which was used for early standard television screens. Nowadays the most common aspect ratio is 16:9 which is used for televisions and computer monitors. 16:9 is a widescreen aspect ratio and also the international standard image format for UHD, HDTV and Full HD. Another popular aspect ratio is 21:9, which is used for high-end computer monitors also known as ultrawide displays. This aspect ratio roughly matches the various anamorphic formats used in film.

You can use the Aspect Ratio Calculator to calculate the above mentioned aspect ratios to find the correct amount of pixels for these types of displays. Or if you need to adapt content for social media posts, such as vertical 9:16 videos with 1080 x 1920 pixels used in Instagram Reels and TikTok.
