Calculating aspect ratios as N:1Ĭalculating aspect ratios as N:1 is a bit simpler. Similarly, if you have an LED video wall that is 550 pixels wide by 75 pixels high (550x75p), then its aspect ratio is 22:3.Īn aspect ratio written in the format W:H is a simplified set of numbers where W is the units of width and H is the units of height. If you were to simplify the fraction 550/75, you would get 22/3 (by dividing both 500 and 50 by the GCF of 25). While an aspect ratio is not a fraction per se, calculating an aspect ratio as W:H uses the same math as simplifying a fraction. So both numbers are divided by this GCF and written as W:H. In this example, the highest number that will divide evenly by both 640 and 480 is 160. W:H = Width divided by the GCF of width and height : Height divided by the GCF of width and height. To calculate an aspect ratio as W:H, divide your width and your height by their greatest common factor (GCF), and write it as W:H, where W is units of width divided by the GCF and H is units of height divided by the GCF.Ī greatest common factor is the highest whole number that will evenly divide by a set of numbers.

Here’s how to calculate aspect ratios both ways. tall box would have the same aspect ratio as a 1mm wide by 1mm high pixel (1:1, square).Īspect ratios can be written as W:H or N:1. Additional portrait ratios include 2:3, 9:16 and 1:5.Īspect ratios are independent of size, so a 3 ft. Any aspect ratio with a height greater than width is classified as such. LED panels).Ī 1:2 aspect ratio is considered a tall or portrait ratio. and 12 square tiles x 24 square tiles (i.e. Examples of 1:2 ratios are 100 pixels x 200 pixels, 450 ft. 1:2Ī 1:2 aspect ratio indicates a height that is double the width. You might not be aware of this fact, but every frame, digital video, canvas, responsive design, and image often has a rectangular shape that is exceptionally precise in proportion (or ratio). Examples of square aspect ratios include 200 pixels x 200 pixels (200×200), 1m x 1m, and 50 widgets x 50 widgets. Aspect Ratio Calculator Use this ratio calculator to check the dimensions when resizing images. 1:1Ī 1:1, or square aspect ratio indicates a width equal to height. Additional examples of landscape ratios would be 3:1, 16:9, and 4:3.
x 300 ft., and 20 led panels x 10 led panels (1:1 panels).Ģ:1 aspect ratios are classified as wide or landscape, since the width is greater than the height.
A 2:1 aspect ratio indicates 2 parts of width for every 1 part of height.
