How many pixels is a cent?

What would be the pixel dimensions for a cent at actual size?

Depends on the resolution.

There are varying sizes of pixels as technology gets better. For example a 17 inch LCD from a few years ago that could max out at 800x600 had 800x600=number of pixels. But now a 17 inch can do 1920x1280 ie full HD has more than twice the pixel exponent on the same size screen. So a pixel is not a pixel is not a pixel. In fact a 17 inch tv now that can do full HD has smaller pixels than a 55 inch tv doing full HD.
If you were going by camera, the distance you are from the coin determines how many pixels it is as a ratio to the number of pixels in the photograph you are taking. For example, in theory you could stand far away from the penny with an 8 megapixel or whatever megapixel camera where the penny is exactly 1 pixel in size. Youd see no details but that would be the size of hte viewable penny in pixels. Or you could be very close, zoom right in to a spot, and have the picture be nothing but a zoomed area, say the date, and in theory the entire penny would then be even more pixels than that camera setting.

So to answer your question, what size pixels are you talking about and at what distance, and then on what monitor ar eyou viewing that picture on. Kinda makes the question unanswerable.

Generally, image software has setting to change the "size" displayed between pixels & inches & sometimes centimeters.


state software used and perhaps someone here can hep you find it.

although as mentioned above, size on a monitor will vary with pixel size the monitor has.

The question, as stated, has no definitive answer - it requires many qualifying points. Cheers, RickO

72 pixels on my monitor.

I have an older 17" monitor and its native resolution is 1280x1024.

17" is diagonal, so actual width of this monitor is 13.375"

A cent is 0.75" in diameter.

0.75 / 13.375 = .056, so a cent at actual size would take up 5.6% of screen width

.056 x 1280 = 71.8, so 5.6% of 1280 pixels is approx 72 pixels.

Just replace your monitor dimensions and your resolution in the calculations above to determine the number of pixels on your screen.

Interesting approach. Still doesnt give a universal answer, but can narrow it down to specific monitor sizes + resolutions.

I think it only requires one. Pixel density of either the input or output device expressed as pixels per unit area (e.g. pixels per square inch).

Did you have others in mind?

Most pixels have 2 dimensions.

MsMorrisine

and if you really want to be a purist, save it in .bmp format or some other non-loss file format.

Well in teh case of monitor sure you can jsut place it flat on the screen and count the pixels, but in the case of a digital camera, distance becomes a variable.

OK, here is a more complete answer:

We'll use my monitor as a baseline of 72 pixels. For any other monitor, the number of pixels (P) is directly proportional to the resolution (R) , and inversely proportional to the screen width (W), so use the following formula:

P = 72 * (R / 1280) * (13.375 / W)
= 0.752 * R / W

So if your monitor is a 21" diagonal with a 16.5" width, and your resolution is set for 1920x1440, the formula would give:

P = 0.752 * 1920 / 16.5 = 87.5

I think you are all approaching it wrong.

You can't set up formulas correctly if you do not have a proper grasp of units.

A cent is a measure of money.

Your monitor has pixels.

Your monitor was purchased with money.

My monitor, with a resolution of 1920 x 1200, has a total of 2,304,000 pixels.

It cost me $475. Or 47,500 cents.

2,304,000 pixels / 47,500 cents = 48.5 pixels per cent

48.5% is definitely a failing grade.

BTW, I think you've all been drinking this fine evening.

Entirely dependant on the monitor. I would say 100 pixels in diameter should be close on average.

Well, if I use my point and shoot digital camera, it can be 3,100,000 pixels. If I use my DSLR, it can be 16,700,000 pixels.

Those calculations just give the width. It is a 2 dimensional object. Well actually it is a 3 dimensial physical object but represetned as 2 for the question. Again, there is no answer. A pixel is not a pixel is not a pixel. Its like asking how many balls fit in a bag without defineing what kind of balls or how big a bag.

yer all wrong theres only 20 up & down...20 left to right!

see!?.......(kinda have to squint yer eyes tho...)

I thought it was obvious that the height would be the same as the width, but apparently not. So if I use my "formula" for calculating the height on my 17" 1280x1024 screen:

P = 72 * (1024/1280) * (13.375/10.75) = 72

So on my screen, the cent would indeed be 72x72 pixels. Again, just replace your dimensions and resolutions in the formula (either height or width).

adam... definitely the only one to get this trick question correct

Again, you are narrowing it down to YOUR screen. Ther veritcal spacing and horiz spacing is not always the same.

No, I was just using my screen as an example. To find the size on your screen:

Pwidth = 0.75 * YOUR SCREEN Horizontal Resolution / YOUR SCREEN Width
Pheight = 0.75 * YOUR SCREEN Vertical Resolution / YOUR SCREEN Width

Seems a very simple formula and will work on any screen, any size, any resolution

My previous formula showed 0.752, but it was due to a rounding error. 0.75 is correct since that is the diameter of a cent...
