How many pixels are in one inch?
Just wondering to know about the pixels in one inch.
This is completely dependent on each individual's resolution and screen size. For instance two users can have a resolution of 1920x1080, but user A has a 22 inch monitor/screen while user B has a 24 inch monitor/screen. User A would roughly have 100 pixels per inch while user B would have roughly 92 pixels per inch.
"Given billions of tries, could a spilled bottle of ink ever fall into the words of Shakespeare?"
100 pixel in 1 inch.
Back in the days when every PC had a 15 inch screen displaying 800x600 pixels there was a standard 75 pixels per inch. This also happened to be 1/4 the standard printer resolution of 300 dpi (dots per inch). So images were displayed 4 x bigger on the screen than they printed out. All very simple.
Today, as others here have already pointed out, there is a very wide range of resolutions and screen sizes, so there is no standard dpi. However, assuming that the most used screen resolution for viewing the web is 1366x768 on a 17 inch screen, the predominant dpi is probably something like 100.
You must have good eyesight if you are using a display showing 1000ppi, do you wear it on your wrist???

Laughing at most of the responses here, especially since the only one that even comes CLOSE to being right is Jedaisouls'. It's a factor of resolution vs physical size, and screens come in all sorts of different ratios of same.
There is no fixed value across devices, saying "72" or "96" is ignorant nonsense... Let's do some math based on some displays I happen to have access to here.
My current 17" laptop -- visible width 15 inches, resolution 1920x1080
Pixels Per Inch: 128
Old 17" Laptop -- visible width 14.25 inches, resolution 1440x900
Pixels Per Inch: 101
MSI Wind U123 Netbook -- visible width 8.75 inches, resolution 1024x600
Pixels Per Inch: 117
My primary workstation 27" IPS -- visible width 23.25", resolution 2560x1440
Pixels Per Inch: 110
Secondary workstation 24" LCD's (one left, one right) -- visible width 20.5", resolution 1920x1200
Pixels Per Inch: 93.6
Workbench 17" LCD -- visible width 13", resolution 1280x1024
Pixels Per Inch: 78.77
14" Junk VGA CRT -- Visible width 11",
1024x768 (what I'd run) = 93dpi
800x600 (what "normal" people run) = 72dpi
21" Viewsonic CRT -- visible width 17.8", resolution 1600x1200
Pixels Per Inch: 89.9
4.5" Cubot GT99 (android phone) -- visible 'long' way 4", resolution 1280x720
Pixels Per Inch: 320
42" Sanyo TV -- visible width 36.5", resolution 1920x1080
Pixels Per Inch: 52.6
Get the idea? (I may have gone overboard here)
Of course with 4k displays (4096x2160) displays coming down the pipe, interface scaling is going to be even more important, which is why declaring fonts or layouts in pixels is shortsighted idiotic nonsense; unless you want people to pretty much HAVE to rely on zoom to use your sites, which of course is why fixed width layouts are idiotic nonsense, since when you zoom those they don't adjust to fit the display resulting in side-scrolling or worse, a broken layout.
Again, guidelines like the WCAG exist for a reason.
Oh, it's also a laugh that Win 2k and XP 'assumed' that desktops ran "normal" claiming 96dpi, and they referred to 8514/large/120%/win7 medium / whateverthey'recallingitthisweek as being a 100% fictional 120dpi, given that at the time most displays people owned were running at 70 to 78dpi, and display resolutions I was running (usually one notch higher) were 90...100dpi.
About the ONLY time you actually got physical PPI matching your OS PPI claims was the old black-and-white original Mac's. See the system on the right side of this pic:
But hey, I've been running 1024x768 or higher on Windows since 1989.
100 pixel equal 1 inch. also you can visit this site for more information. http://www.translatorscafe.com/cafe/...pixel_%28Y%29/
96.0000000000011 pixel are in one inch
... and look, more posts by people who have no clue what they are talking about.
It depends on resolution and screen size. Majority of laptops and PC monitors have 75-100 ppi, but some of them can have almost 300 ppi (for example Toshiba's Satellite P50t which has the resolution of 3840×2160 - 282 pixels per inch).
