PPI calculator is the abbreviation of pixel per inch calculator which refers to the density of a pixel on a digital image. Similarly, it also refers to the pixels in a screen on display. To make it easy, pixels are actually a combination of tiny lights that come together to form a display on any screen. These pixels make form an image on the screen thus the quality of pictures deeply depend on them.
Many pixels combine to form pictures that can be less or more in number depending on the quality of the picture. To know about the number of pixels in an image, we refer to a term which is known as pixel count. It is the total number of pixels that are present across both the dimensions (width and length) of an image.
PPI calculator tool
Online PPI calculator is an easy to use and simple tool that can calculate the PPI of the display of any digital device. This calculation tells you about the quality of display and gives you precise resolution values of the device. PPI is the measurement of pixels per inch on a display screen that appear as squares in front of the calculator tool.
The calculator tool ensures that both the vertical and horizontal PPIs are identical to count the pixels. Besides, it also measures the distance between centers of two pixels from the backend. This calculator has four sections to fill in order to calculate the pixels of the screen. Let us now get to know about the step by step instructions on how to use PPI calculator tool.

Steps of calculating PPI
- Our PPI calculator tool automatically detects the horizontal and vertical resolution from the screen of your device. In case the tool does not detect the resolution, refresh the page and you will see that it fills automatically.
- The next step is to enter the size of the screen in inches in the “size in inches” section of the tool. Once you enter the size then click on the calculate button.
- The tool will come into action and calculate the pixels per inch of the screen within no time. Once the calculation is done, you will see the results in the ‘resolution –Y’ section of the tool.
What is Pixels per Inch?
Pixels are dots or small building blocks that come together to create an image on a screen of a digital device. These dots of colors combine in a sequential manner to create a sound looking image on display. When they come together in their order, the picture becomes visible and users can clearly see it on their computer or mobile screens.
Let us take a puzzle picture as an example to explain the formation of images with the help of pixels. In a puzzle the blocks are actually the colorful dots that need to be arranged in a proper way. When all the blocks are arranged in their perfect sequence, they combine the colors to form the picture on display. Whenever you zoom on these pictures, you can see the pixels in the form of colorful dots.
Elements of pixels
By now, you are familiar with how the pictures are created on your screen with the help of pixels. As you know, pixels are colorful dots that create an image but what is the nature of these dots? Actually, they are tiny dots of colors that are blue, green and red in nature which are sub-pixels in an image. This group of sub-pixels combine together to create a single pixel on the screen.
Due to additive color processing, they are not visible with the naked eye because they are mixed with each other within the pixel. This process is the mixture of RGB (red, green and blue) into a new color which is why you always come across RGB in pixels per inch. It is only available on digital screens and does not show up in paper prints.
Importance of pixels per inch
Whenever we come across any image online, it is usually visible with the naked eye. You may have come across photos that have a clearly visible or a blurry display. It is these pixels that measures the pixels of a photo and determine the quality of these images. For instance, a picture with higher number of pixels will have a better quality than the one with lesser pixels.
All those who love to watch movies, take photographs or play games on a computer or mobile want to have a clear display. For this purpose, they have to calculate the PPI of the screen and the image to know about the quality of the display. To check the quality of a screen, you will have to understand how to use this online tool.
Pixels form the display of a screen therefor they are of great importance in the digital world. A damaged or dead pixel can cause an obstruction on the display and can reduce the quality of an image. Besides, pixel resolution also determines the quality and visibility of a screen. Thus, it is always necessary to choose a device that has a high number of functioning pixels.
Frequently Asked Questions
Is higher PPI equivalent to better quality?
Yes, with the more number of pixels on a screen, you will have a better image quality. It is because of the fact that higher number of pixels creates higher resolution images that look sharp and clear.
Which one among DPI and PPI is a better option to take prints?
DPI is a better option to take prints as it creates a higher quality image in the form of prints. Remember that it always consumes a lot of ink per print therefore you should go for a lower DPI to take prints.
What role does PPI play in printing resolution?
PPI changes can help you in changing the resolution of the printable image but the size will be the same. This means that the image quality will be a little lower but it will have the same size just like the one on the screen.
What is the main difference between DPI and PPI?
The main difference between both these terms is that DPI is the dots per inch in an image in print form. On the other hand, PPI is the number of pixels in a single inch of picture frame on the computer screen. Sometimes, people use it interchangeably as they are unaware of the main difference between them.
