Default ccd cmos size

Is there a web site that actually shows the differences in sizes between the different imaging chips? I see that some prosumer chips are listed as 1/1.8" and then others...like the 10D cannon's size is listed in millimeters. Is there a way I can see the relative differences without doing the math? It would be neat to see the sizes from the smallest to the largest of the chips.

Here's a site where you can convert inches to millimeters:

The 1/1.8 ICX452 (C-5050) is the 5Mpixels version of the 2/3 ICX282 (F717, D7's, CP5700, E-20):

The dimensions are in mm in their repective datasheets. The 10D sensor is 22.7x15.1mm. As a reference the new 4/3 E1 is 19.7x15.04mm... so they are quite larger! And where they all fit in:

Here's what we have in the Olympus E-1 review:



Left to Right: The common 1/1.8" (most 3-, 4- and 5-megapixel cameras), 2/3" (E-20n) and 4/3 System CCD imagers. The imager in the E-1 has four times the spatial area of the E-20n's imager. The diagonal measurement of the FT-CCD sensor is 22.3mm.





The EOS-1Ds is a full-frame sensor, same size as 35mm film, the D60 sensor is a little bigger than the Olympus E-1 imager shown above. The G2 uses a 1/1.8" size image sensor.
