This is a guide covering DPI in photography.

Understanding DPI is essential for photographers who want to produce high-quality prints or digital images. It affects the clarity, resolution, and overall quality of your photos, and it can be the difference between a stunning masterpiece and a blurry mess.

In this article, we will dive deep into the concept of DPI in photography, explaining what it is, how it works, and why it matters. Whether you’re a seasoned pro or a beginner, this knowledge will help you improve the quality of your photos and take your photography skills to the next level.

Well, we’ve got you covered!

What is DPI in photography?

DPI refers to the number of printed dots within one inch of a printed image.

The best result you will get with paper photos is between 300 dpi to 600 dpi.

How Do I Know the DPI of an Image?

There are many ways to check the DPI image or change it.

Like file explorer in windows, you can see the DPI of an image while the photo editing app allows you to change the image size or DPI resolution.

The window file explorer app is the easiest way to check the DPI and resolution of an image, so let’s see the step-by-step process.

  • Click the window logo in the bottom left corner and write file explore on the text bar. You can also open the file explorer app to click the window and E button on your keyboard simultaneously.
  • You can also search for the location of the image which you want to check by using file explorer.
  • Place a right-click on the image, then click on properties at the bottom of the list.
  • In the properties list, click on the Details tab.
  • Scroll down to the “Image” section of the menu.
  • In the last bar, you can see two options for your image DPI: “Horizontal Resolution” and “Vertical Resolution.”

How does DPI affect resolution?

The matrix of the dots is enough to make fool the human eye because digital print is just an optical illusion.

A fine dotted pattern makes a beautiful image, and viewers think that they might see an image in real life.

To get that fine image, you must meet the following conditions:

  • the density of dots
  • the size of the image
  • the distance from the observer must be at a suitable range for our illusion to work

It’s basically an accurate measurement to judge how finely we have to print so that our image comes smooth and detailed.  


DPI is doing well when it comes to the printer, but when we are talking about digital graphic designs and image sizes, then the confusion begins between two different concepts PPI (pixel per inch) and DPI (dot per inch), because all the image files, digital camera, and electronic screens work in pixels. DPI is all about how we calculate the density of pixels.

In other words, DPI refers to the number of printed dots within one inch of a printed image. PPI refers to the number of pixels within one inch of an image on a computer monitor.

What is a Good DPI for Photos?

Generally, a 600 DPI scan is the best image resolution and pixel count for photos printed on paper.

Final Remarks

In the end, we can say that even the best design image can ruin just because of poor resolution. That’s why DPI is very effective in photography.

Frequently Asked Questions

What is good DPI for photos?

The ideal DPI (dots per inch) for photos depends on the purpose and size of the final image. Generally, a resolution of 300 DPI is considered suitable for high-quality prints, while a resolution of 72 DPI is sufficient for digital images displayed on screens.

Is 300 DPI high resolution?

Yes, 300 DPI (dots per inch) is generally considered high resolution, particularly for printed materials. It results in sharp and detailed images that are suitable for printing in large formats or high-quality publications.

Should I use 300 or 600 DPI for photos?

The choice between 300 DPI and 600 DPI (dots per inch) for photos depends on the specific context and purpose of the image. Generally, 300 DPI is suitable for most printing needs, while 600 DPI is typically used for extremely high-quality prints or specialized applications.
