Enter the width and height of the image into the calculator to determine the proportion ratio. This calculator can also evaluate any of the variables given the others are known.
Image Proportion Formula
The following formula is used to calculate the proportion of an image.
PR = W / H
Variables:
- PR is the proportion ratio
- W is the width of the image (pixels)
- H is the height of the image (pixels)
To calculate the proportion of an image, divide the width of the image by the height of the image. The result is the proportion ratio, which can be used to maintain the aspect ratio when resizing the image.
What is an Image Proportion?
Image proportion refers to the relationship between the width and height of an image. It is usually expressed as a ratio, such as 4:3 or 16:9. Maintaining the correct proportions when resizing an image is important to prevent distortion or stretching. For example, if an image originally has a 4:3 proportion and it’s resized to a 16:9 proportion, the image will appear wider and shorter than the original.
How to Calculate Image Proportion?
The following steps outline how to calculate the Image Proportion using the formula PR = W / H.
- First, determine the width of the image (W) in pixels.
- Next, determine the height of the image (H) in pixels.
- Next, gather the formula from above = PR = W / H.
- Finally, calculate the Image Proportion.
- After inserting the values of W and H into the formula and calculating the result, check your answer.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Width of the image (W) = 800 pixels
Height of the image (H) = 600 pixels
