手机开发中不免会遇到分辨率、DPI、PPI和屏幕尺寸等术语,那就弄弄清楚这些概念的真正含义。 分辨率 分辨率这个词在很多地方都有,比如相机、视频、扫描仪。这里说的就是显示器的分辨率。显示器是由一个个像素点(pixel)所组成的,一般所说的显示器分辨率是1280x720就表示这个显示器水平方向有1280个像素,垂直方向上有720...
1. 名词理解 屏幕尺寸(screen size) 屏幕尺寸(screen size),是屏幕的对角线长度,一般讲的大小单位都是英寸。 DPI (dots per inch) dpi是(英文Dots Per Inch)(每英寸所打印的点数)的缩写,是打印机、鼠标等设备分辨率的单位。国际上都是计算一平方英寸面积内像素的多少。这是衡量打印机打印精度的主要参数之一,一...
How to Compute PPI Screen? What are Screen Size, Screen Resolution, and PPI Screen Size:The screen size or the display size is the size of your mobile screen. In modern smartphones, it can vary from 4.7 inches to 9.7 inches. Screen Resolution:A mobile screen uses a lot of pixels to ...
Step One: Find the Screen’s Diagonal The first step to calculate PPI is to measure the screen’s diagonal size in inches. Most displays, screens, monitors, and televisions are sold by their diagonal measurement, which should be marked on the screen or its documentation. ...
Screen Dimensions Apple iPhone 14 Pro screen size is 6.1 inch with ~ 87.0% body ratio of actual device size. Physical dimensions for Apple iPhone 14 Pro device is 5.81 x 2.81 x 0.31 INCH or ( 147.5 x 71.5 x 7.9 MM). Displaying of Units are in this order "Height x Width x Thicknes...
Then, you can calculate the PPI as the ratio between the number of pixels along the diagonal and the diagonal screen size: PPI = dₒ/dᵢ where dᵢ is the diagonal screen size in inches. You probably noticed that you can also enter the width and height of the display into the PPI...
In case you have a 27″ 1080p monitor, you’d need to be 42″ (107cm) away from the screen for it to be ‘Retina’, and so on. You can visitthis websiteand calculate at what distance a certain screen size/resolution becomes retina or check the table below, which consists of the...

This is a free easy to use converter which you can use to convert PPI to DPI automatically. Convert pixels per inch (PPI) to dots per inch (DPI) online.
PPI is an interesting metric, but it cannot be used by itself as a sharpness benchmark because the distance between our eyes and the display is as important as the pixel density itself. If you bring your screen closer to your eyes, you will see the pixels. If you move the device furthe...
