Convert Pixels to Inches

pixels to inches conversion chart

How to convert pixels to inches

To convert pixels to inches, you have to divide pixels by resolution. For example, a 600 x 400 pixels image displayed on a 96 DPI screen is going to have 6.25 x 4.17 inches when printed.

To find the resolution of an image in DPI, you need to know the image width in both pixels and inches, then divide the image width in pixels by the image width in inches. For example, a 600 pixels wide image that’s also 6.25 inches wide, has a resolution of 96 DPI.

To print an image at some specific dimensions, you can check the DPI of your screen by consulting the manufacturer specs. Alternatively, you can use our handy-dandy method explained below.

Use the chart on the right for standard pixels to inches conversions, or the conversion calculator below.

How to find DPI of your screen?

The easiest way to find your display DPI is to take a ruler or a measuring tape to measure the red portion of the screen from the right. Go to size chart below to find DPI resolution of your display. The most common value is 75 DPI for most of monitors.

Uncommon measurement? Calculate DPI below.

Measurement Screen DPI
3 inches 100 DPI
3 ¼ inches 92 DPI
3 ½ inches 85 DPI
3 ¾ inches 80 DPI
4 inches 75 DPI
4 ¼ inches 70 DPI
4 ½ inches 66 DPI
4 ¾ inches 63 DPI

What is a pixel, what is an inch?

Pixel definition provided by Dictionary.com

A pixel is the smallest element of an image that can be individually processed in a video display system.

Inch definition provided by Dictionary.com

An inch is a unit of length, 1/12 (0.0833) foot, equivalent to 2.54 centimeters.

When you have to convert pixels to inches?

Usually, converting pixels to inches is a good way to see how your images will look to a different screen or projector. If you have a presentation, and you want to add some images in that presentation, you may want to see how this image will show on the projector that you will use. Knowing the width and height of the image (in pixels) that we will use in the presentation, we can calculate the image width and height in inches, to make an idea how it will be displayed on the projector or another display, bigger or smaller.

      Hi Yoshi. There’s a checkbox on the right side of the calculator that says “Activate custom DPI”. Check that box and enter your DPI value. 20 DPI in your case.

      First off you need to know your printer DPI. Most printers have 300 DPI. If that’s the case, you can use Inches to Pixels conversion tool, select 300DPI and convert your sizes to pixels.

      Hi Thrushitha,

      First you need to find out your monitor DPI, either by using DPI Finder from above, or looking into your pc settings.

      Then you can convert Inches to Centimeters to match your requirements.

      As an example, if your monitor has 60 DPI, then your sizes in pixels will be approximately: 213×165 px.

        Thank you. In Monitor specifications, they have not mentioned its DPI. I use Samsung LED monitor, model : S22F355FHW

        If i go through an expression (which i found on some discussion forum) , i get 102 as dpi. But if i go through this site in measuring red bar i found 3.6inch = 83 dpi.

        Expression what i followed is

        Resolution set = 1920 * 1080
        = 16 : 9

        we have width = 16x and height = 9x

        Screen measurement along diagonal = 21.5 inches

        Therefore, we have (16x * 16x) + (9x * 9x) = 21.5 * 21.5
        337x^2 = 462.25
        x^2 = 1.37166

        Therefore x = 1.17118

        Hence width =16x = 18.7389
        height = 9x = 10.5406

        Therefore Area = width * height
        area = 197.5192878

        PPI = Sqrt of ((1920*1080)/(area))
        = 102 pixels

        I found this expression in one of the sites when they are speaking about DPI calculation
        Can you please suggest me, which value is right

          Hi Thrushitha,

          I don’t really understand what you want to accomplish…

          You want to draw an image of 9x7cm that will be displayed on your monitor, or that size should be when printed?

          If you draw the picture at 9x7cm on your screen, then display it on a projector or another display, the sizes will change, because the other devices might not have the same DPI as the monitor you’re working on.

            Hi,
            I am sorry for confusing you. First i need to know what is the dpi of my monitor. (Samsung LED monitor, model : S22F355FHW). Then after knowing it i want to know how many pixels are used to draw an image say 9 x 7 cm.

            If i know what is dpi, then it ll be easy to caluculate number pixels for my respective images

            To know DPI, one method was to use that RED BAR in this website and another was by using expression.

            By red bar, i measured red bar using scale which resulted in 3.6inch = 83 dpi.
            By using expression, (explained in earlier chat), i got 102 dpi.

            I want to know which is right.

          • n1nj@ says

            July 13, 2017 at 4:28 am

            The formula is correct. I tested it with two monitors and a mobile phone display, and it gives me the exact result as when using the measurements of the red bar.
            Are you sure you have the measured the red bar correctly in inches? For a DPI of 102, it should have between 2.92 and 2.94 inches.

            Hi,

            I went through that link and found my monitor resolution is 1536 x 864. when I use this value in my expression, i find PPI = 82 , which is almost equivalent to this red bar calculation 83.

            In my system configuration, it is showing resolution as 1920x 1080 at 125%.
            but with 100%, that link shows 1920 x 1080 and red bar measures about 2.9 inch thats equal to 103 dpi. whixh is equal to my expression calculation also. now i got clear idea about ppi and resolution.

      Hi Nicky,

      The DPI varies from one device to another, so that’s why you’re getting different results.

      Also, you should calculate based on the output device DPI (in this case, the printer).

    I just don’t get this…I need to submit a photo and this is the request: The .jpeg should be 6 inches on the longest side, 72DPI

    I don’t see dpi on my resizing, just % and pixels. Usually, submissions are supposed to be at 1920 pixels minimum, but that makes my image HUGE according to this converter. Under properties on my photo, it does show it set at 300dpi, but of course I don’t know how to change that, or if it matters, since the image will be viewed on the judges computer. Can anyone help me using very simple terms?

      Hi Coleen,

      According to Inches to Pixels converter, your image should have 450px on the longest side.

      The process I followed: Selected 75 DPI from the dropdown menu, entered 4 in the Inches box and the calculator showed me 450px as the result.

      You can use an app like Gimp to change the photo resolution to 72. See here how to do it: http://cdn.makeuseof.com/wp-content/uploads/2015/10/gimp-change-dpi.gif

    I can easily convert my JPEG image (that average 5+ MB File size) to a TIFF image, with an average of 15+ MB File size, but how do you size the picture to a print size of 8″ x 10″, and at 300 DPI?

      For the moment the converter doesn’t know how to convert any other DPI’s than the preset ones. I will update the converter soon, and you should be able to calculate the DPI value by yourself and type other DPI values to convert your dimensions into inches.

        I have kind of craft thing made out of paper with lot of curve forms on it. I like to have drawing of the the item for laser cutting machine to make a copy of it. Can I dimension such such curves and sections using pixels?

          Hi Ted,
          Theoretically, you can. Just be sure you have specified the correct DPI.
          Could you share a pic of your project? It sounds very interesting.
          Have a nice day,
          Jeffrey
