In short,pixel density is the ratio between a screen’s size and itsresolution. For instance, the standard 1920×1080 Full HD resolution will result in a different pixel density (or pixels per inch) on a 24″ screen (92 PPI) and on a 27″ screen (82 PPI). ...
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...
A display or image of 1920x1080 pixels is 1080p resolution – commonly known as ‘high definition’. To work out PPI, you’d also need the diagonal measure of the screen or image in inches. Pixel count can then be divided by the number of inches. ...
Megapixels are most commonly used to calculate the resolution of stills. Digital video is still calculated in terms of pixels, but the megapixel quantity is used infrequently. Instead, video resolution is typically calculated as width-times-height. When you see a video’s resolution described as ...
The resolution of a CCD is a function of the number of pixels and their size relative to the projected image. CCD arrays of over 1,000 x 1,000 sensors (1 Mega-pixel) are now commonplace in scientific cameras. The trend in cameras is for the sensor size to decrease, and cameras with...

Pay attention to resolution Here is a quick overview of some basic resolution concepts: PPI (pixels per inch)refers to how many pixels will appear in a single inch of any digital screen. PPI, also known as pixel density, is used to measure the clarity of images. The higher the PPI, the...

What is a pixelated image? A pixelated image refers to an image that appears blocky or jagged due to the visible individual pixels. This usually happens when an image is displayed at a low resolution or when it is enlarged beyond its original size. When the pixel density is insufficient to...
The physical size of a pixel depends on the set resolution for the display screen. If the display is set to its maximum resolution, the physical size of a pixel will equal the dot pitch, or the dot size, of the display. But if the resolution is set to something less than the maximum...
