Making sense of the sensor size?

Those are not described in that way; only compact cameras use the fractional
inch method. Nikon and some other DSLRs mostly use a sensor of either 23.7 x
15.6 mm or 23.6 x 15.8 mm, in either case roughly the same as the full APS-C
format and often referred to by that term.

Whatever it's called, the 2/3 type is the largest sensor generally found in
any digicam. Its actual size is about [6.6] x [8.8] mm.
Other common sizes are 1/1.8 and 1/2.5 -- there are several other sizes as
well, but those appear to be the ones most often used today.
What are the actual physical dimensions of 1/1.8 and 1/2.5 sensors? Do
DSLR sensors really have more than six times the area of a 2/3 sensor? Wow.
Thanks for the informative article.
