What Is a Picture’s DPI and How Can You Change or Increase it?

What is the DPI of an Image? In this modern world, there are many people who want to click pictures or take selfies from their smartphones or DSLR cameras. Most people prefer to take pictures and print them for decoration purposes.

There are many companies that like to print a big banner and use it for promotional purposes. When printing large posters, it’s really important that your image has a high DPI for the most efficient printing. DPI is Dots per inch, defines the clarity of the print. There are many ways to increase the DPI of the image.

What is DPI?

DPI stands for “dots per inch” and is a specification for adjusting and printing the print resolution of an image.

A print is made from millions of tiny ink dots. The DPI setting determines how many dots the printer leaves per square inch of the image. You need to understand how DPI works because it controls the two most important things in printing:

  1. The quality of your print.  In simple terms, a higher DPI means a higher quality print. Most good home printers can output at 300dpi, and professional printers are much higher.
  2. The size of your print.  A pixel in a digital image is equivalent to a dot in a print. So if you print an image that is 300 pixels wide at 1800 dots per inch, the printed image will be six inches wide. Print the same image at 180 dpi and it will be 10 inches wide.

How Does DPI Affect Your Prints?

Here is a picture to show. Below are two lines of 40 identical squares of the same size and color. Frames are less tightly packed in the top row, which equates to a lower DPI; and the bottom line is more tightly packed for a higher DPI.

The effect is obvious. On  a lower DPI  the line gradient is much less smooth. You can see clear edges against each of the squares. The line is also much longer.

On  Higher DPI  the line gradient is much smoother. Almost seamless. The line is also much shorter.

This shows you the balancing act you often have to do when adjusting the print resolution: size and quality. If you’re working with low resolution images, you need to strike a balance between the two.

Whenever possible, you should always save your work in as high a resolution as possible. Because resizing your image to enlarge will not improve print quality.

What DPI Should You Use?

All this begs the question: What is the best DPI for printing? The standard rule of thumb is that  you should aim for 300 dpi . It’s a great quality for photos, and it’s questionable how much detail the human eye can discern beyond this level.

But don’t worry if your image is too small to print at 300 dpi. The intended viewing distance of the print plays a big part in the resolution you need. For images you hold on hand, such as photographs, brochures, or magazines,  target 300 dpi or higher , but 250 at a time will suffice.

If you’re going to frame it with posters or pictures, you can get away with a lower resolution because you’ll mostly be looking from a few meters away. 200 dpi should be fine , even slightly lower. This also applies when printing on different materials such as canvas.

And such. The further you intend to look at your image, the lower you can set the resolution. A billboard banner designed to be seen from across the street can be printed at  as low as 20 dots per inch .

How to Check the DPI of a Picture

To find the DPI of an image in Windows, right-click on the filename and choose  Postings  >  Details . You will see the DPI   in the section labeled  Image Horizontal Resolution  and  Vertical Resolution . On Mac, you need to open the image in  Preview  select  Tools > Adjust Size . labeled solution .
