Common screen dimensions are listed in the table below (the most common diagonal dimensions in inches as of 2020 are bolded). If the display is not listed, then the following equations can be used. Note that D is the diagonal (in centimeters or inches), W is the width (in pixels), and H is the height (in pixels).
10 meters – wavelength of the highest shortwave radio frequency, 30 MHz; 10.2 meters – length of the Panzer VIII Maus, the world's largest tank; 12 meters – height of the Newby-McMahon Building, the world's littlest skyscraper; 23 meters – height of Luxor Obelisk, located in the Place de la Concorde, Paris, France
The following is a comparison of high-definition smartphone displays, containing information about their specific screen technology, resolution, size and pixel density.It is divided into three categories, containing smartphones with 720p, 1080p and 1440p displays.

For a pixel pair (one white and one black pixel) this gives a pixel density of 128 pixels per degree (PPD). 6/6 vision is defined as the ability to resolve two points of light separated by a visual angle of one minute of arc, corresponding to 60 PPD, or about 290–350 pixels per inch for a display on a device held 250 to 300 mm from the eye.

A 50 m × 25 m (164 ft × 82 ft) Olympic swimming pool, built to the FR3 minimum depth of 2 metres (6.6 ft) would hold 2,500 m 3 (660,000 US gal). The US National Institute of Standards and Technology (NIST) defines the Olympic swimming pool as 1 million litres, which is the approximate volume of the smaller FR2 pool.
The main tasks of rasterization (including pixel processing) are: [16]: 2, 3.8, 23.1.1 Determining which pixels are covered by each geometric shape in the 3D scene or 2D image (this is the actual rasterization step, in the strictest sense)
The difference between the semi-major and semi-minor axes is about 21 km (13 miles) and as fraction of the semi-major axis it equals the flattening; on a computer monitor the ellipsoid could be sized as 300 by 299 pixels. This would barely be distinguishable from a 300-by-300-pixel sphere, so illustrations usually exaggerate the flattening.
