什么是DPI 计算器？
A DPI (Dots Per Inch)计算器 helps gamers and designers calculate mouse sensitivity and screen resolution settings for optimal precision.
如何使用
输入您的 mouse DPI, in-game sensitivity, and screen resolution. The 计算器 向您展示r effective sensitivity and pixels per 360-degree turn.
常见问题
What is DPI?
DPI stands for Dots Per Inch. It is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
How do I calculate pixel size from physical dimensions?
To find the pixel size, multiply the physical width or height (in inches) by the DPI value. For example, a 2-inch wide image at 300 DPI is 600 pixels wide.
How do I calculate print size from pixels?
To find the physical print size, divide the pixel width or height by the DPI. For example, a 1200 pixel wide image at 300 DPI will print at 4 inches wide.
What is the standard DPI for high-quality printing?
The industry standard for high-quality photographic printing is 300 DPI. For standard documents or newspapers, 150-200 DPI is often acceptable, while large format billboards may use as low as 30-75 DPI due to viewing distance.
What is the difference between DPI and PPI?
DPI (Dots Per Inch) refers to the physical output of printers, while PPI (Pixels Per Inch) refers to the digital resolution of a screen or image file. Though often used interchangeably in casual conversation, they refer to distinct concepts in digital imaging.
Does changing DPI change file size?
Not directly. Changing DPI without resampling (changing pixel dimensions) does not affect file size. File size only changes if the pixel dimensions (width x height) change.
Why is my image blurry when printed?
Blurry prints usually occur because the image has too few pixels for the print size (low DPI). Ensure your pixel dimensions are high enough to support the print size at 300 DPI.
