DPI/PPI Calculation Formula:
From: | To: |
DPI (Dots Per Inch) refers to the number of dots a printer can produce in a one-inch line. PPI (Pixels Per Inch) refers to the number of pixels displayed per inch on a digital screen. In Windows, DPI scaling affects how content is displayed on high-resolution screens.
The calculator uses the following formula:
Where:
Windows DPI Scaling: Windows scaling percentage affects how content is displayed. The effective DPI is calculated by adjusting the physical PPI based on the scaling factor.
Details: Understanding your display's DPI/PPI is crucial for graphic design, web development, and ensuring proper display scaling in Windows 10. Higher PPI displays show more detail but may require scaling for comfortable viewing.
Tips: Enter your screen resolution in pixels, the diagonal size of your screen in inches, and select your Windows DPI scaling setting. All values must be positive numbers.
Q1: What's the difference between DPI and PPI?
A: PPI refers to pixel density on screens, while DPI refers to dot density in printing. In Windows settings, "DPI" often refers to display scaling.
Q2: What is a good PPI for a monitor?
A: Standard monitors are around 90-110 PPI. "Retina" or high-DPI displays are typically 200+ PPI. Higher PPI provides sharper images but may require scaling.
Q3: How does Windows DPI scaling work?
A: Windows scaling increases the size of UI elements on high-PPI displays to maintain readability. At 150% scaling, elements are 1.5x larger than at 100%.
Q4: Should I use Windows scaling or application scaling?
A: For most users, Windows scaling is sufficient. Some applications have their own scaling settings that may work better for specific use cases.
Q5: How do I find my screen resolution and size?
A: Right-click on desktop > Display settings shows resolution. Screen size is usually listed in the monitor specifications or measured diagonally.
