DPI to File Size Calculator

Calculate File Size







Formula

The formula to calculate the File Size (FS) is:

\[ \text{FS} = (\text{W} \times \text{DPI}) \times (\text{H} \times \text{DPI}) \times \text{CD} / 8 \]

What is DPI?

DPI stands for Dots Per Inch and is a measure of the resolution of a printed or digital image. It indicates the number of individual dots that can be placed within a linear inch. Higher DPI values mean more detail and sharper images, while lower DPI values result in less detail and blurrier images. DPI is commonly used in printing and scanning to ensure that images are reproduced with the desired clarity and detail.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{FS} = (8.5 \times 300) \times (11 \times 300) \times 24 / 8 = 7650000 \times 24 / 8 = 22950000 / 8 = 2868750 \]

The File Size (FS) is 2,868,750 bytes.
