What is PPI? Is it important? How to Calculate it?

PPI Stand for Pixel Per Inch. PPI is commonly known as pixel density. In order to understand about PPI you need to first know the exact and basic meaning of pixel. I have already explain the pixel. As the name suggest PPI is the no of  pixel per inch. It is also known as Pixels Per Centimeter (PPCM). It is an very important factor of screen resolution. Suppose in one inch there is one thousand pixels, if we increase it to two thousand than image quality will be more clear than before because pixels in per inch increased. So generally  it is said that more the pixels in per inch, more the image quality in the screen.

How to Calculate Pixel Per Inch(PPI)?

What is PPI? Is it important? How to Calculate it?

let us take an example of smartphone with an screen resolution of 1920x1080 pixel which is 5.5 inch  from both the corner as shown in the figure. Do you remember Pythagoras theorem in which if we get two side of the triangle we can find the third side. So we can find PPI in the same manner. It is already shown in figure. 

 Note: If you want to calculate pixel per centimeter than you can take centimeter instead of inch in the formula.  

conclusion:

In this article you have learned about PPI, how it is calculated and its importance. If you likes our article and want to appreciate us you can share our articles with you're friends and relatives and join us on our social media handle.

Screen Resolution And Their Types

Hello friends you have heard one of the word screen resolution such as HD, Full HD, etc while buying or seeing the features of smartphone, tablet, computers, laptop or smart television. Here we provide you with some of the basic knowledge, so that you can easily understand about this topic. 
Screen Resolution And Their Types

Screen Resolution and Pixels:

In order to understand about screen resolution we need to first understand the exact and basic meaning of term pixel. So firstly we have to know about pixel in order to understand  screen resolution.

What is pixel?

Screen of any devices whether it is smartphone, tablet,  computers, laptop or smart television are made up of small components known as pixel. It is the smallest components which can generate colors. In one pixel there are three small pixel known as sub pixel. These sub pixel consist of three color commonly known as Red, Green and Blue (RGB) color. These colors are universal colors which is capable of combining and generating new colors. So pixel use colors mixing technology to appear different colors in the screen.

Screen Resolution And Their Types
Screen view of mobile
Screen resolution is the number of pixels appear on horizontal and vertical axis in the screen. Let us take an example of mobile display which is of 1920x1080 pixels. Here p is determined as pixel. If we count pixels in horizontally basis it will be 1080 pixels  and on vertical basis it will be 1920 pixels as shown in figure. So below are the various types of screen resolution which you have heard nowadays.

NOTE: Screen resolution are generally written in horizontal and vertical form i.e. 1920x1080 pixel but in the smartphone screen it is reversed as shown in the figure.
