This easy-to-use PPI calculator identifies the dots per inch (DPI), pixels per inch (PPI), and display size in centimeters and inches for any device, ranging from desktop PCs through to smartphones and other portable devices.PPI is a measurement of resolution or pixel density that denotes the number of pixels that appear within a 1-inch line on a display. This PPI calculator assumes that the pixels are square; as such, the horizontal and vertical PPI are identical.In addition to calculating the PPI, the calculator also identifies the total number of pixels on the display and the distance between the center of the two pixels, which is also referred to as the dot pitch and is the inverse of the PPI.How to Manually Calculate PPIVarious approaches can be employed to calculate PPI. The method that is most commonly employed involves calculating the pixels per inch from the diagonal screen size (in centimeters or inches) and the number of pixels along the horizontal and vertical edges of the display.Step one: Calculate the number of pixels that appear on the diagonal using the following formula:dp = √(w2 + h2)Where w is the number of pixels that appear along the horizontal edge, and h is the number of pixels that appear along the vertical edge.You can then use the output of this calculation to determine the PPI as the ratio between the number of pixels that appear along the diagonal screen size as follows:PPI = dp / diWhere di is the diagonal screen size in inches.Example Calculation of Pixels per Inch (PPI) & Dot Pitch (DPI)Let's apply the formula outlined above to determine the PPI of a desktop computer screen.First, measure the diagonal size of the computer display. For this calculation, we'll say it is 10 inches.Record the vertical and horizontal pixel count. For this calculation, we'll say they are 600 and 800 pixels respectively.We can now compute the number of pixels along the diagonal as follows:dp = √(w2 + h2) = √(8002 + 6002) = √1,000,000 = 1000We can use this output of this calculation to compute the PPI as follows:PPI = dp / di = 1000 / 10 = 100.As such, the desktop computer screen has 100 pixels per 1-inch line on the display.We can go one step further to calculate the dot pitch as the reciprocal of the PPI:dot pitch = 1 / 100 in = 0.01 in = 0.254 mmYou may also be interested in our eDPI Calculator or TV Viewing Distance Calculator

The 7-site skinfold calculator is a sophisticated tool used by fitness professionals and researchers to assess body composition and estimate body fat percentage. Unlike simpler methods like BMI or basic body fat scales, the 7-site method provides a more comprehensive assessment by accounting for fat distribution patterns across different body regions. Research has shown this method to be accurate within 1-3% when performed correctly by trained professionals.

And ensure it fits in your room without overwhelming the space. A 1080p projector can support screen sizes up to 150 inches diagonally. However, the ideal projection screen size depends on your viewing distance. For a comfortable experience, maintain a distance of about 1.5 to 2.5 times the screen’s diagonal measurement. Yes, screen size matters for a projector. A larger screen provides a more immersive experience but requires sufficient viewing distance. A smaller screen may be suitable for smaller rooms or closer viewing distances. Based on your room and preferences, choose the projector screen size that balances practicality. Your projection screen size should be determined by your room size and viewing distance. Measure the distance between your seating area and the intended screen location. Use a projector screen size calculator by XTEN-AV or online resources to determine the optimal screen size for your setup. While a bedsheet can technically be used as a projector screen in a pinch, it’s not recommended for optimal image quality. Bedsheets often have wrinkles and uneven surfaces that can distort the projected image. Invest in a proper projector screen for the best viewing experience. There is no single standard projector screen size. However, common sizes for home theaters range from 100 to 120 inches diagonally. The ideal projector screen size for a room depends on the available space and viewing distance. To determine your projector screen size, measure the diagonal length of the viewable area on the screen. If you don’t have a screen yet,Diagonal of a Rectangle Calculator
