USER ID - think of a piece of paper as a FF Sensor. Halve it, and you have an APS-C Sensor.
Halve it, again - and you have a Micro Four Thirds Sensor ...
Halve it, again ... and you have a 1" sensor.
Halve it, again ... and you have a 1/2.3" (bridge) sensor ...
Then measure the square area ... and double it back again,
and again and again and again - and you're back at Full Frame !!!!!

Forget the square area. It has no effect
on IQ, only on cost. Linear measure is
what determines image size.
Your visualization with the sheet of paper
is quite handy for getting the general idea.
But there are small discrepancies of a mm
here, a mm there, that do add up in the
real world result, not to mention the 4x3
vs 3x2 difference in shapes. If your sheet
of paper analogy were 100% perfect then
m4/3 would have a 3x2 shape and APSC
would have a 4x3 shape ... but the actual
fact is the exact opposite. Go figger :-O
When you halve a rectangle you get a new
shape. When you again halve the smaller
new rectangle, you get the original shape:
36x24, 24x18, and 18x12, easy ratios to
see without great math ability ! But these
are NOT the real world ratios for the two
smaller formats :-(
