According to Whatis.com it varies depending on your screen resolution, here's the explanation:

You can even get rulers to measure them.

I believe it does depend on the size of your monitor and your resolution.

Sorry but you are wrong there. A "." is made up of quite a few pixels otherwise you would not be able to see it.

I think it is about as big as a gnats digit.

It depends.

Lots of things have pixels.

CCDs (the sensor in your digital camera, or webcam, or video camera.

LCD/TFT displays.


FAX machines.


On a "big" screen at a sports ground, the pixels are quite large. The famous NY Times screen used to have standard light bulbs as pixels. (Now it's lotsof LEDs).

On an astronomical CCD, the pixels might be about 10 microns --- 1/100 th of a millimetre,

On a CRT, .12 mm used to be considered quite good.

Yea thanks people.Just wondering if the guy who bought my ds has a dead pixel.

nintendo will replace/fix your DS free of charge within if any dead pixels become too bothersome, ofcorse they encourage you so wait a few months to see if that becomes the case.


"With a small number of Nintendo DS screens, one or two dots on the screen may appear to be "stuck" on a particular color, such as white or red. This effect is caused when a particular pixel (the dots that make up the screen) is not working properly, even with the high quality standards set by LCD manufacturers. You will find this situation is common in many LCD devices, (PC monitors, televisions, cell phones, etc.).

It's important to understand that this issue will remain limited to the pixels you have already noticed. The problem will not get any worse and you should not expect to see the problem in any other areas of the screen.

We suggest that you use your system for a few weeks to determine whether this interferes with your enjoyment of game play. If, after using your system for awhile, you feel that this tiny dot is too distracting, the Nintendo DS does carry a one-year warranty. We are happy to inspect and, if necessary, fix your system at no charge within the warranty period."
