# Aspect Ratio Calculator

Aspect Ratio Calculator This aspect ratio calculator computes the missing value within a particular aspect ratio. Aspect ratio is the parameter demonstrating what ratio between width and height of a rectangular is. When we see such designations like 16:9 and so on we may guess that it is exactly the ratio we are talking about. While aspect ratios are measurements of the height and width, they are often reduced to the smallest usable ratio in order to fit perfectly in every medium. To achieve a perfect aspect ratio, you must employ the use of an aspect ratio calculator. It reduces any margin of error. Check the what is aspect ratio post.

The aspect ratio of an image defines the proportion between its width and height. It is always expressed as two numbers separated by a colon (x:y). For example, images with the aspect ratio of 16:9, no matter how big or small, will always have the width of 16 and the height of 9 units of the same length. Therefore, 16 centimeters wide and 9 centimeters high image as well as 32 centimeters wide and 18 centimeters high image has the same 16:9 aspect ratio.

## How to Use Our Calculator

In order to find out the aspect ratio of an image or video, both width and height should be known in advance. If you already have these two measurements just insert them into the calculator above and aspect ratio will be calculated as a result. All calculations are being made automatically to assure efficiency, accuracy, and fluidity!

## Portrait vs. Landscape

Additionally our aspect ratio calculator will provide the mode for you picture or video. It will be determined based on the measurements provided. Mode for the images or videos which are taller than it is wide will be 'Portrait' and those with the bigger width than height will be 'Landscape'.

## Other Important Details

Please note that measurements should always include ONLY the size of the actual image or video, and NOT to include additional video player dimensions or picture frames / borders. Sometimes video players or image frames could add up to 20 – 30 pixels and as a result aspect ratio will not be as it truly is.

The first number is the tire width in millimeters.
The 2nd number is used to calculate the sidewall height or 'aspect ratio' , by percentage. So, the sidewall height of a
The 3rd number (generally preceded by an 'R') is Rim Diameter in inches. This is the diameter of the rims bead seat base, not the diameter of the outer rim edge. The rim edge, or lip, extends past the tire bead seat to hold the bead and stop the tire slipping off the rim.
When we say a rim has a inch diameter, we mean that the diameter of the bead seat base measures inches. The outer rim edge diameter will actually measure more, depending on the design.

If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray mist too!
