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.

    SO easy! Makes defining image size in Lightroom, which uses ONLY pixels a breeze; no need to send to PhotoShop to get the inches!

    Hey all y’all, I found a tool that converts Pixels to Inches.

    I used it to successfully convert a wiring diagram to print out on an 8½ x 11 sheet of typing paper.

    I want to calculate as how many pixels is needed to draw that image.

    Also I mean that image size is in cm, i need to mention that size in pixels
    Can anyone help ?

    Thanks in advance.

    • 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.

          • 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.

          • Rated 5 / 5 stars.

            Yes sir. I am using measuring tape (tailor) 60 inches in length , to measure red bar. I am getting 3.6inches .
            on led monitor with 1920 x 1080 resolution set.

            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.
            U helped me a lot.
            Thanks a ton sir :-)

    so, if i create an image on my phone (which i have calculate from your site is 150dpi) and its size is 4500 on the longest side (30 inches) why is it when i send an email to a computer (75dpi) and print it, it doubles to 60 inches? why is there not a standard? like and inch is an inch. why does it vary so?

      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?

    I want total document of less than 500kb & document width of 820px, night of 842px. According to your dimensions it will be ok for 75 dpi. Actually is more than 500kb. Suggest me.

      If the application know to resize the signature it should be ok. It will not be the same aspect ratio, but it’s close enough. You can check our Aspect Ratio calculator to make sure it has the same aspect ratio when you scale down you signature photo.

    Hi,

    Your website is really helpfull.

    But please can you please tell me the formula of how you calculate dpi

    Reply

    • Hi Fahim, glad you enjoy it.

      About your question..
      The formula to calculate pixels into inches is: Pixels / DPI = Inches
      From this formula we can extract DPI as: DPI = Pixels / Inches

      Hope it helps. If you have further questions, I’m here.
      Have a nice day,

    Image Submission requirements: The image submission must be a TIFF image of 300 DPI, picture size of 8″ x 10″, and submitted on a DVD.
    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?

        In Photoshop click on TOOLS and where it shows a capital T ,click on it to highlight it which it opens a bat at the top of PC which shows another Capital T and in the box it says PIXELS I want it to say inches
        Reply

        • I checked my Photoshop install and you cannot change to inches. You can at most to change to millimeters.
          Photoshop menu > Preferences > Units & Rulers > Change to Millimeters.
          You could use an online tool to convert millimeters to inches I think.

    The red bar measures 2 and 7/8″ on my screen. Can you please
    tell me what my DPI is ? It must be more than 100.
    Thanks
    Reply

    • Hi Nagaraj.
      If I’m right, 2 7/8” should be 2.88 inches in decimals. In this case, your DPI is 104.
      You could use the DPI calculator from the left of the table for uncommon measurements like this one.
      Hope it helps.

    • Hi Shantal,

      Your DPI value is 150.
      Stay tuned, I will release the new version of the converter soon and you will have the option to calculate the DPI value by yourself.

    I may be a little confused. When I measured the red area I got 2 5/8 inches. Does that seem right? If so, what would my DPI be? Thanks for your help!

    • Hi Joann,

      Your DPI is 114.

      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.

      Tell me your values in pixels and I’ll do the conversion for you.

      Thank you for your feedback,
