Calculate New DPI





Formula

To calculate the new DPI:

\[ D_{new} = \frac{D_{current} \times R_{new}}{R_{current}} \]

Where:

DPI Definition

DPI stands for Dots Per Inch and is a measure of the resolution of a digital image or display. It indicates how many individual dots can be placed in a line within the span of one inch. Higher DPI values generally mean higher resolution and more detail in the image or display.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ D_{new} = \frac{300 \times 1920}{1080} = 533.33 \]

The new DPI is 533.33.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ D_{new} = \frac{150 \times 2560}{1440} = 266.67 \]

The new DPI is 266.67.
