# What Is Pixel Density And Pixels Per Inch (PPI)?

Have you ever wondered how many pixels your computer screen has? What is Pixel Density and Pixels Per Inch (PPI)? If you don’t, then this blog is for you. This blog will look at what PPI and pixel density are, why it matters, and how you can use them to get a better screen.

Pixels per inch, or PPI, refers to the number of pixels within an inch of a display. A display made with a higher PPI has more vivid details than a display with a lower PPI. The term pixel density is used interchangeably with PPI.

Pixel density is the resolution at which a device is able to display graphics and it’s measured in pixels per inch. It’s usually simpler to explain what it’s not. It’s not the number of pixels that a device has as some devices have the same number of pixels but have different pixel densities.

However, there is a lot of confusion around pixel density and what it means. I will try and make things simple in this blog and hopefully answer some of the questions that people have about pixel density.

## What is Pixel Density?

Pixel density is the number of pixels combined in an area of the screen. It is measured in pixels per inch (PPI). The pixel density of screens is an important factor to consider when buying a computer. That is because higher pixel density means more pixels packed into the same sized area. This results in a sharper display, as you can see more details.

Let’s take an example. If you are using a smartphone and you have a 5-inch screen, then its pixel density will be about 440 PPI. If you are using a 7-inch screen, then its pixel density will be about 564 PPI. So, it means that if you are using a smartphone with a lower pixel density, it will look blurry. Hence, it is best to have a screen with a high pixel density.

## What is Pixels Per Inch (PPI)?

The Pixels Per Inch (PPI) value is a measure of the resolution of an image. It is the number of pixels in a linear measurement of an image. The pixel is the smallest unit of digital image data. So, the more pixels you have in an image, the higher resolution it will be.

You can also say that the PPI value is the number of pixels that make up one inch. If you look at the PPI value of an image, you will get to know how many pixels make up one inch. For example, the PPI value of the image below is 72.

If you look at the image above, you can see the difference between the size of the photo and the phone’s camera. If we zoom in on the image, we will get to know how many pixels make up one inch.

### Why Does Pixel Per Inch (PPI) Matter?

It is very important to have a high PPI value because it is directly proportional to the clarity of the image that you see on the screen. For example, if you are looking at an image on a device that has a PPI value of 300, then it means that every single pixel is 3 times bigger than the actual size of the image. This is the reason why we get to see very clear and crisp images when we use a phone that has a high PPI value. So, it is a must to choose a good quality monitor with a high PPI value.

### How Does Pixel Density Matter?

Pixel density is one of the most important factors when it comes to choosing the best laptop for yourself. If you are using a lower resolution screen then you will be able to use a smaller display. The same thing applies to mobile phones.

If you are buying a laptop, then you should first know about the screen resolution and then check the pixel density. It is important to know that a higher resolution means a bigger display, but it doesn’t mean that it will provide you with better results.

## Conclusion

Pixel density is a term that describes how many pixels exist when an image is viewed at a specific distance. PPI describes the same measurement but is generally used to describe the screen on a device, such as a smartphone or a tablet. It is a measurement of the number of pixels per inch of a display. Having a high pixel density will provide a clearer and more detailed image. The higher the PPI, the sharper the image will appear.

We’ve all heard the term “retina display” being thrown around, but what does that mean? Well, if you have a screen with a high PPI, your eye won’t be able to detect the pixels, making the images on the screen appear super clear and sharp. Most of the time, the higher the PPI, the better the picture quality, but this isn’t always the case.

If they have the same screen resolution, the screen with a higher PPI will appear to have smoother text and images(ne x monitor images).
