DPI Change Calculator

Formula

To calculate the new DPI:

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

Where:

\(D_{new}\) is the new DPI
\(D_{current}\) is the current DPI
\(R_{new}\) is the new resolution
\(R_{current}\) is the current resolution

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:

Current DPI (\(D_{current}\)) = 300
New Resolution (\(R_{new}\)) = 1920
Current Resolution (\(R_{current}\)) = 1080

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:

Current DPI (\(D_{current}\)) = 150
New Resolution (\(R_{new}\)) = 2560
Current Resolution (\(R_{current}\)) = 1440

Using the formula:

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

The new DPI is 266.67.
