Pixels Per Inch PPI Calculator For Any Screen Size

Your Result will appear here

The full form of PPI is “Pixels Per Inch.” This refers both to the density of pixel within a digital image and a fixed number of pixels that the screen displays.

On the other hand, pixel-count refers to the total number of pixels across the width and length of an image that is called image dimensions in pixels.

PPI Explanation

Let’s take it this way; these are the smallest building blocks that build an image.  Take an example of a puzzle picture that comes in slightly bigger blocks or pieces, which kids play with and affix all the pieces to make an image.  Those building blocks will get visible when you zoom in the picture on your screen. The small colored square will appear on your screen – these are pixels.

Now we comprehended that an image is built by the small pixels, but do you know what those elements are that create the pixel? There are blue, green and red elements within the pixel; in other words, subpixels that create one pixel. A human naked eye can’t see them because additive color processing (RGB) mixes them into a hue which appears within the pixel. This is the reason why ‘Pixel Per Inch’ uses the RGB (red, green and blue colors).

One thing worth considering is that these pixels or additive color processing don’t exist in prints, it only shows up in electronic display like digital photography, monitors, TV screens etc.

But why do you need to get into pixels’ quality that much if you can see the image quality with your naked eye? Well, it is not about just seeing the quality, it’s about measuring it. The higher the number of pixels, the better the image quality will be.

If you are a gaming enthusiast, photographer or just want to enjoy watching movies, you may need to calculate your PPI first to figure out the screen’s or image quality.

 Let’s check it out how are you going to do that: 

PPI calculator tool

Ranging from portable devices, desktop PCs, laptops to smartphones and any other device, this handy, easy to use PPI Calculator calculates display size in pixel per inch that also gives resolution values.

Pixel per inch is a measurement of pixel density or resolution that signifies the number of pixels that appear within 1-inch line on your display. The calculator sees the pixels as square and makes sure that the vertical and horizontal PPIs are identical.

This PPI calculator not only measures the number of pixels but also measures the distance between the center of the two pixels from the backend.

As said earlier, the usability of this tool is a lot more convenient than other tools; let’s check out how can you calculate your screen’s pixels:

Tutorial

The tool has 4 sections, including:

  • Horizontal resolution
  • Vertical resolution
  • Size in inches
  • Resolution-y

This tool automatically calculates the horizontal and vertical resolutions. The only input you will give in is your screen size in inches. Put in the size in inches and press the ‘calculate’ button.

Instantly you will get the results in pixel per inch density.

The best part is, you don’t have to add the horizontal and vertical resolutions. Once you refresh the page, it’ll pick up your screens resolution directly.

No one is an expert in every field, and many of us are not technology experts. Constantly changing and always moving forward, one can often feel as if he is left behind. Fortunately, there are always ways to improve our knowledge base. For instance, have you ever wondered what is meant by a dot or pixel? Ever wondered what the difference is? Or how one or both might affect your image’s quality?

FAQs

You better get your hands on the following FAQs to further clear your concepts regarding PPI.

Does higher PPI mean better quality?
A large number of PPI means higher resolutions that lead to creating a more detailed image and creating a crisp, high-quality display.

Fewer pixels mean lower resolutions, but if those few pixels are too large in size, they may become visible but cannot create as much high quality as the higher number of pixels do.

Is DPI better than PPI to take prints?
High DPI equals higher quality image with a superior tone, but it also indicates longer print times and more ink expense per print. If ink expense is a concern, lower DPI can help tremendously. Because DPI is based on two dimensions, halving it will actually produce a quarter of the ink dots made. For instance, 100 DPI is the equivalent of 10,000 dots per square inch, whereas 50 DPI produces only 2,500 ink dots per square inch.
How much does PPI important for printing resolution?
PPI is more specific in its meaning, and changing PPI is done primarily to change the size of a printable image.

There are two ways that changing PPI can affect an image. This is determined by whether a program is set to re-sample or not. To put it simply, if re-sample is off, proportions are constrained and changing the PPI of an image also changes the width and height of that printable image.

It is important to recall that changing PPI changes the “printable” size, not the on-screen size. Therefore, there is also the option of using re-sampling. With re-sample on, changing the PPI will not change the size of the printable image (only the resolution), but lower PPI will appear small on screen. Cameras and scanners produce images at PPI larger than most websites will display.

Is there any visible difference between PPI and DPI?
While both terms affect resolution and image quality, they do have their own applications and are not exactly interchangeable. However, do not surprise to find these terms used incorrectly. DPI is often used in place of PPI despite the actual difference in definition.
What’s the difference between pixels and dots?
We’ve already seen the PPI definition, so it is time to compare it with DPI.

Dot per inch or DPI and PPI, however, are the same elements. The only key difference between both is that PPI is made of pixels and DPI is made of dots. In other words, there’s no visible difference when it comes to measuring the screen quality since the pixel is usually considered as the “dot” of the display or an image. The difference gets more complex when we compare DPI vs PPI at a deeper level.
