Image Equivalent Ratio Calculator

Formula

The formula to calculate the missing dimension of an image is:

\[ OW = \frac{OH}{DH} \cdot DW \]

Where:

\(OW\) is the original image width
\(OH\) is the original image height
\(DW\) is the displayed image width
\(DH\) is the displayed image height

Image Equivalent Ratio Definition

An image equivalent ratio is a mathematical relationship between the original dimensions of an image and its displayed dimensions. This ratio helps in maintaining the aspect ratio of the image when resizing it, ensuring that the image does not appear stretched or compressed. By using the image equivalent ratio, you can accurately scale images to fit different display sizes while preserving their original proportions.

Example Calculation

Let's assume the following values:

Original Image Height (OH) = 1200 pixels
Displayed Image Height (DH) = 600 pixels
Displayed Image Width (DW) = 800 pixels

Using the formula to calculate the Original Image Width (OW):

\[ OW = \frac{1200}{600} \cdot 800 = 1600 \]

The Original Image Width (OW) is 1600 pixels.
