Equivalent ratios or equal ratios are two ratios that express the same relationship between numbers. You can use the equivalent ratio calculator to solve ratio and/or proportion problems as required by entering your own ratio to produce a table similar to the 'Equivalent Ratios of 16.9:20.9 table' provided below. This ratio table provides an increasingly list of ratios of the same proportions where the numerator and denominator are a direct multiplication of the multiplying value (m_{x}). Ratio tables are very useful in math for calculating and comparing equivalent ratios, although most will likely use a ratio calculator to calculate equivalent ratios, it is also useful to have a ratio table where you can quickly cross reference associated ratios, particularly when working with complex math equations to resolve advanced math problems or physics problems. As a useful reference, we have included a table which provides links to the associated ratio values for the ratio 16.9:20.9, for example 16.9.1:20.9, 16.9:20.9.1, 16.9.1:20.9.2 and so on. We hope you will find these quick reference ratio tables useful as you can print and email them to yourself to aid your learning or a useful learning aide when teaching ratios to math students.

## About Aspect Ratio

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.
