What is pixel? How it looks like?

Pixel is a tiny square dot but the very powerful indeed. If you are in digital platform everything you see is made of pixels like in science everything is made of atoms.


The blue square dot in the above picture is a pixel. Let’s take an example of  a rectangle box of 10px width and height 8px. So how many pixels are there in this box? Let me demonstrate you.


There are 80px in the above rectangular box. You use simple mathematics multiplication formula to calculate the total pixels.

Pixels are in image

This is the image of Patan Durbar Square which I took it from my Sony Xperia Zr back 2-3 years ago. You can see how beatiful this image is but where are the pixels. I’ll show you how pixels are formed to give a nice view of this image.

Fig. 1.c Patan Durbar Square

Here you can see some pixels of image that I have zoom to 3200% to its original image ratio. Now you can imagine how many pixel will be there in one image. You can calculate total pixels in image with simple mathematics if you know the width and height pixels of any image.

Fig. 1.d Pxiel showing
Fig. 1.d Pixels in the image

This image dimension is 800×450 pixels so there are total 360,000 pixels in this image.


If this tiny square dot(called pixel) collected with millions of different colors you can form any kind of image you want.
