We’ll go over What is the difference between PPI and DPI? What is image size in pixels and why does it matter? Where to size in Powerpoint? How big is a digital picture really? How to resize in Photoshop and Illustrator Using search power to help you determine image size Graphics Resources at PSU

DPI (dots per inch) vs PPI (pixels per inch) PPI vs. DPI Both describe

DPI (dots per inch) vs PPI (pixels per inch) PPI vs. DPI Both describe the resolution (or clarity) of an image, they’re not the same thing. PPI describes the number of square pixels that show up in an inch of digital screen (usually between 67 -300). DPI, on the other hand, is a printing term referring to the number of physical dots of ink in a printed document. (Via https: //99 designs. com/blog/tips/ppi-vs-dpiwhats-the-difference/)

PPI vs. DPI Takeway: Think of the PPI input as a way to adjust the physical size – not the resolution – of the eventual print-out. Decreasing the PPI, thus increasing the size of the printout, may seem to produce a lower quality image because the pixels are larger and more visible. But remember, this is only a relative gauge of quality; if you were to stand further away, the image would appear as clear as it did before. The absolute resolution of the image has not changed; there are still as many “pixels” relative to the picture as there were before. So the way to increase the resolution of an image is to produce an image with more pixels, not increase the PPI. (Via https: //99 designs. com/blog/tips/ppi-vs-dpiwhats-the-difference/)

PPI vs. DPI For example, if you are printing a 150 ppi image at 600 dpi, each “pixel” will consist of 16 dots (600 dots/150 “pixels” = 4 rows of 4 dots per “pixel”). As a rule of thumb, the higher the DPI, the better the image’s tonality and the smoother its color blending will be (it will also use more ink and take longer to print, so keep that in mind for personal home printing). 150 dpi considered the minimum standard for high quality photographic reproduction in books and magazines. 85 dpi - Newspapers 45 dpi Billboards go as low as this, but you can’t tell because you’re viewing from very far away. Typical dot matrix printers are capable for 60 – 90 dpi, inkjet printers 300 – 600 dpi, and laser printers 600 – 1, 800 dpi. (Via https: //99 designs. com/blog/tips/ppi-vs-dpi-whatsthe-difference/)

There are 2 ways that you can change the print size, by resampling or by not resampling. To Resample, or Not to Resample That is the Question Not resampling is what you normally want to do, this will only change the size of the print. Using resampling will actually change the number of pixels (and thus the file size) in order to match the print size. So for instance, if you don't resample, changing the PPI setting will increase or decrease the print size (it will increase if you drop the PPI, it will decrease if you increase the PPI). With resampling, if you change the PPI, you will loose pixels (if you set the PPI to a lower value) or you will have pixels created (if you increase the PPI). Creating pixels is a bad idea, they get generated by the computer and the results aren't usually that good. Throwing away pixels is fine as long as you won't need the bigger size later (that's why it's usually a good idea to save the original large file). (Via: https: //www. andrewdaceyphotography. com/ar

People regularly discuss digital images in terms of DPI, which stands for Dots Per Inch. DPI - The Math Further The DPI of a digital image is calculated by dividing the total number of dots wide by the total number of inches wide OR by calculating the total number of dots high by the total number of inches high. Example: An image is 1200 x 1800 pixels (dots) and 4 x 6 inches in size. That means our digital image is 1200 dots high by 1800 dots wide and 4 inches high by 6 inches wide. Our digital image has 300 DPI. We can figure that out by dividing the number of dots wide by the number of inches wide: 1800 dots wide/6 inches = 300 dots 1200 dots tall /4 inches = 300 dpi (information via https: //www. iprintfromhome. com/mso/understandi ngdpi. pdf)

Find The Information, No Digging Required Easily Find PPI On a pc: Right click

Find The Information, No Digging Required Easily Find PPI On a pc: Right click on the image, and select Properties, then on the top tabs choose Summary, it should display it here, if it doesn't then click on Advanced which should be on that summary tab. On a mac: Hold Apple + i (or command + i). This should pull up an info box. Etc: Image editors such as Photoshop Element or Paint can tell you the dpi of a file. Click on Image info.
