PPI calculator assist to unearths the pixels in keeping with inch (PPI), dots consistent with inch (DPI), and show size for any selected tool.

This dpi calculator allows to discover a dot consistent with inch (DPI) that is referred to as the range of revealed dots contained within one inch of an picture printed with the aid of a printer.

what is the PPI method?

In case you need to calculate PPI, then you definately have to divide the length of the diagonal in pixels by means of the duration of the diagonal in inches. additionally, you may use the PPI calculator to get pixel in step with inch.

The PPI system is:

PPI = (diagonal in Pixels)/ (diagonal in Inches)

PPI = d_p / d_i

formulation for Diagonal length in Pixel:

The system to calculate the period of diagonal in pixel is as follows,

dp =√(width)2 + (Height)2

Where,

Dp =√(width)2 + (height)2

A way to use the Pixel according to Inch Calculator:

Don’t to worry; our pixel density calculator is completely loaded with a user-pleasant interface. You simply must observe those steps to get ppi and dpi resolutions.

Inputs:

  • Initially, you have to input the display width in (Pixels) in the discipline of ‘Horizontal law.’
  • Right after, you must input the display screen top in (Pixels) within the discipline of ‘Vertical decision.’
  • Very subsequent, you need to enter diagonals display length in (inches) in the subject of ‘Diagonal display screen length.’
  • After this, pick out your device from the dropdown of this pixel calculator either it's far a computer, cellphone or a tablet.
  • Eventually, hit the calculate button of this screen dpi calculator and get the Pixels according to Inches (PPI), overall Pixels, and Dot Pitch.

Outputs:

  • Pixel in step with Inch (PPI).
  • Dot pitch.
  • display size.
  • total pixels of screen.
  • Pixel in line with square inch (PPI2)
  • Diagonal period.
  • Aspect ratio.

The way to Calculate Ppi Manually (Step-through-Step)?

Before everything, for the calculation of ppi you have to calculate the variety of pixels that seem at the diagonal using the given method:

dp =√(width)2 + (Height)2

Where,

‘width’ represents the wide variety of pixels that looks alongside the horizontal edge.

‘peak’ represents the variety of pixels that seem alongside the vertical facet.

The output of this calculation can be applied to the system that we stated earlier.

That is:

PPI = d_p / d_i

wherein,

‘di’ represents the diagonal display screen length in inches.

let’s strive an instance for manual calculation.

Example:

Suppose your screen has a horizontal resolution of 1800 pixels, a vertical resolution of 900 pixels, and a diagonal screen size of 20 inches.

How would you calculate the PPI (Pixels Per Inch) of your screen?

Solution:

Step 1:

Calculate the diagonal resolution (dp) using the Pythagorean theorem:

\(d_p = \sqrt{(horizontal \, resolution)^2 + (vertical \, resolution)^2}\)

\(d_p = \sqrt{(1800)^2 + (900)^2}\)

\(d_p = \sqrt{3,240,000 + 810,000}\)

\(d_p = \sqrt{4,050,000}\)

\(d_p \approx 2012.46 \, pixels\)

Step 2:

Now, calculate the PPI using the formula:

\(PPI = \frac{d_p}{d_i}\)

Where:

  • \(d_p\) = diagonal resolution (2012.46 pixels)
  • \(d_i\) = diagonal screen size (20 inches)

\(PPI = \frac{2012.46}{20}\)

\(PPI \approx 100.62\)

Thus, the screen has a pixel density of approximately 100.62 PPI.
