## What Is PPI?

PPI pixels per inch is the term used to define the resolution of screens such as mobile displays, computer monitor, television screen. It is used as a density measurement unit of displays which describes to the sharpness of the screen. In simple words, its pixels per inch is the number of pixels in a square inch surface. The higher the value of PPI the more detail of the image you can see. But the human eye is made to see these details till a particular value after which the higher number doesn’t matter. While buying a television or mobile phone, it is important to know the pixel density as low pixels per inch will end up in bad image quality on display screens. Our ppi calculator is your best companion that helps to calculate PPI of a display within a couple of seconds.

### What is The PPI Formula?

If you want to calculate PPI, then you ought to divide the length of the diagonal in pixels by the length of the diagonal in inches. Additionally, you can use the PPI resolution calculator to get pixel per inch.
The PPI Formula is:
PPI = (diagnol in Pixels)/(diagnol in Inches)
PPI = d_p/= d_i

Our PPI calculator also uses the above formula while calculating PPI of a display.

## Calculate Total Pixels, PPI, and Dot Pitch With Our PPI Calculator:

Well, come to the point, the team of calculator-online provided an interactive PPI calculator through which you can able to calculate the pixel density or resolution of your screen display depending on screen dimensions and the pixel count. For some people, this tool is referred to as a dpi calculator, the tool that shows the number of pixels, which can be fitted on a 1-inch line.

### How to Use Our PPI Calculator:

Don’t to worry; our pixel density calculator is fully loaded with a user-friendly interface. You just have to follow these steps to get total pixels, PPI, and Dot pitch.

• First of all, you have to enter diagonals screen size in (inches) in the field of ‘Diagonal Screen Size.’
• Right after, you ought to enter the screen height in (Pixels) in the field of ‘Vertical Resolution.’
• Very next, you have to enter the screen width in (Pixels) in the field of ‘Horizontal regulation.’
• Finally, hit the calculate button of this pixel calculator and get the Pixels Per Inches (PPI), Total Pixels, and Dot Pitch

## Why There Is a Need to Know About PPI?

It is quite essential to determining Pixels Per Square Inch (PPI) as it helps to choose the right computer monitor, phone, television, laptop, or camera. Once PPI calculated, you will get a better idea as to what the optimal screen resolution for these devices is. Apart from it, it is also useful to graphic designers that need to figure out the scale of an image or pixels to inches conversion.

Calculating pixel density is not an easy calculation as it involves diagonal display screen size, horizontal pixels, and vertical pixels. You can’t calculate ppi it manually you’ll need the help of our screen ppi calculator to get the idea of the best image quality product between many products.

## How to Calculate PPI (Manually)?

The most prominent method that can employ to calculate PPI is according to the diagonal screen size in (cm or inches), the number of pixels along the vertical and horizontal edges of the display.

At first – you ought to calculate the number of pixels that appear on the diagonal using the given formula:

The formula is:

dp = √(() w^2 + h^2)

Where;

‘w’ represents the number of pixels that appears along the horizontal edge

‘h’ represents the number of pixels that appear along the vertical edge

The output of this calculation can be applied to the formula that we mentioned earlier.

That is:

PPI = dp / di

Where,

‘di’ represents the diagonal screen size in inches.

## DPI Vs PPI:

When it comes to DPI, it stands for Dot Per Inch. It is referred to as a physical characteristic of a printer – yes, every printer prints dot that when put next to each other comprise a photo, and each dot contains a physical size. DPI is also said to be as the maximum resolution that a printer is capable of. No doubt, low-end printers have lower DPI, and on the other hand, high-end printers have higher DPI. In simple words, it is the number of dots a printer can print per inch.

Pixel Per Inch or PPI definition is already described above, and even you come to know about the functionality of our PPI calculator. Now, compare both terms – you come to know that DPI is the term that stands for dot per inch, on the other end, PPI is also the same but with pixels instead of dots. Keep in mind; there are no such major differences between both terms since the pixel is considered as the dot of the screen. But, when we compare both at a deeper level, it might be got complicated. You might be thinking that how to calculate dpi of the screen, you can get the ease of dpi calculation with the help of dpi calculator.

Here are some formulas that you need to know while doing pixel per inches calculations:

### Convert Pixels to Inches:

Knowing about the pixel to inch conversion is immensely important as it helps when you are going to print a physical copy of the image or displaying it on a larger screen. You can readily convert pixels to inches with the ease of the given formula:

The Formula for pixels to inches is:

Pixels / DPI = Inches

### Converting Inches to Pixels:

However, converting pixels to inches can be assisting in getting a digital image to a physical image, inches to pixels conversion can assists you bring a physical image into a digital form. You just have to stick on the given formula:

The formula for Inches to Pixels is:

Inches x DPI = Pixels

Thankfully, you come to know about both conversions!

## When You Have To Convert Pixels to Inches?

Typically, converting pixels to inches ensure that how your images will look to a different screen/projector. If you have a presentation, and you are going to add some images in it, then you ought to see how this image will show on the projector that you are going to utilize. You can utilize the above formula to convert pixels to inches.

### How Many Pixels In An Inch?

There is not any actual answer of how many pixels in an inch – It depends on the size of the pixel as not all pixels are created equal.

Additionally, the dots per inch of the display determines the smallest pixel size you can display on your device, but remember that there’s nothing stopping you (or more precisely your graphics driver) from displaying larger pixel sizes that are same as fewer pixels per inch.

But, if you are going to try to display a larger pixel size than an exact integer multiple of your displays native Dot Per Inch, then some of the pixels will get smeared across the edges of the dots, and as an outcome, you’ll get a fuzzy text, lines etc.

But, you can unfold the question of how many pixels per inch with some standards that are:

0.01 pixel (X) – 0.0001041667 in
0.1 pixel (X) – 0.0010416667 in
1 pixel (X) – 0.0104166667 in
2 pixel (X) – 0.0208333333 in
3 pixel (X) – 0.03125 in
4 pixel (X) – 0.041666667 in
5 pixel (X) – 0.0520833333 in
6 pixel (X) – 0.0625 in
7 pixel (X) – 0.072916667 in
8 pixel (X) – 0.083333333 in
9 pixel (X) – 0.09375 in
10 pixel (X) – 0.104166667 in

### How to Measure Monitor Size?

No doubt, it is critical to measure the monitor screen accurately to make sure the proper fit of your computer filter. So, to figure out the filter size, you have to measure diagonally from one corner to the opposite diagonal corner. Make sure that you only measure the viewable screen area; there is no need to include the dimensions of the screen’s frame or casing.
