Pixel density
Understanding Pixel Density: What It Is and Why It Matters Pixel density is a crucial aspect of modern displays, whether they're in smartphones, tablets, televisions, or computer monitors. It impacts the clarity, sharpness, and overall visual experience of a screen. But what exactly is pixel density, and why should you care about it when choosing a device or display? Let's dive in. What Is Pixel Density? Pixel density refers to the number of pixels displayed in a given area of a screen, typically measured in pixels per inch (PPI). It essentially tells you how many individual pixels are packed into each inch of the display. A higher PPI means more pixels in each inch, leading to a sharper image. Conversely, a lower PPI means fewer pixels per inch, which results in a more pixelated or less sharp image when viewed up close. Formula : Pixel Density (PPI) = √(Horizontal Pixels² + Vertical Pixels²) / Diagonal Size of Screen (in inches) This formula calculates the number of pixels th...
