An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...
Paper size standards govern the size of sheets of paper used as writing paper, stationery, cards, and for some printed documents. The ISO 216 standard, which includes the commonly used A4 size, is the international standard for paper size.
Visualization with paper sizes in formats A0 to A8, exhibited at the science museum CosmoCaixa Barcelona An A4 paper sheet folded into two A5 size pages. ISO 216 is an international standard for paper sizes, used around the world except in North America and parts of Latin America.
Thus a printer translates the pixels into a series of dots using a process called dithering. The dot pitch, smallest size of each dot, is also determined by the type of paper the image is printed on. An absorbent paper surface, uncoated recycled paper for instance, lets ink droplets spread — so has a larger dot pitch. [3]
The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...
This number lets the printer or software know the intended size of the image, or in the case of scanned images, the size of the original scanned object. For example, a bitmap image may measure 1,000 × 1,000 pixels, a resolution of 1 megapixel. If it is labelled as 250 PPI, that is an instruction to the printer to print it at a size of 4 × 4 ...

Calculate the scaled pixel size as 1 ⁄ 96 in × (56/28) = 1 ⁄ 48 inch (0.53 mm). Calculate the DPI of the TV as 2160 / (30 in / √ 9^2 + 16^2 × 16) ≈ 82.61 dpi. Calculate the real-pixel count per logical-pixel as 1 ⁄ 48 in × 82.61 dpi ≈ 1.721 pixels. A browser will then choose to use the 1.721× pixel size, or round to a 2× ratio.
