How many inches equal one pixel?

Answer 1

It depends upon the physical resolution of the display unit and its manufacture. There can be between about 70 pixels per inch and 325 pixels per inch. (or each pixel is between approx 0.014 in and 0.0031 in wide) - from this the limitations of the resolution than can be displayed is derived.

For example, I have an 19 in CRT monitor which can physically display 1600 px by 1200 px over an area of approx 14.4 in by 10.8 in; which means that there are 111 pixels per inch, making each physical pixel approx 0.009 in. Other resolutions of output (1280x1024, 1024x768, 800x600, 640x480) are achieved by overscanning the pixels, sometimes using more than 1 physical pixel to display the pixel (eg 800x600 is achieved by displaying 4 pixels for each pixel (a 2x2 grid) of the output, making the pixels approx 0.018 in in this case, or approx 56 px/in).

My laptop display is approx 13 in by 8¼ in with a physical resolution of 1280x800 which gives 96 px/in and thus each pixel is approx 0.0104 in (as given by Lifesnadir above). Again, other resolutions are achieved by over scanning pixels.

Another 17 in CRT monitor I have has a dot pitch of 0.28mm which gives approx 91 px/in or each pixel is 0.011 in for its native resolution of 1280×1024.

According to a pixel to inches converter, 1 pixel equals 0.010416667 inches.

However, I'm unsure whether the size of 1 pixel changes or depends on monitor screen size. Hopefully, another person will comment on that area.
