Portion sizes growing with American waistlines
Food servings are bigger than 20 years ago, but most unaware, study says
All well and good, right?
A 1994 informal survey found that the standard plate size in the restaurant industry grew in the early 1990s, from 10 inches to 12.
“That holds 25 percent more food,” Schwartz said. “That really makes a difference in how much our plates can hold and how much we eat from them.”
New math?

(pi)*6^2 = 113.0973...
78.5398/113.0973 = .694
The bigger plate would seem to be 1.44 times the area of the other.

Incidentally, the analysis above isn't taking into account the difference in plate-rim-width between a 10" and a 12" plate. The ratio of effective plate area would be
(PI*[(10-n1)/2]^2)/(PI*[(12-n2)/2]^2)
= [(10-n1)/(12-n2)]^2
Granted, if we want the result to be 1.25 then...
SQRT(1.25) = (10-n1)/(12-n2)
SQRT(1.25)*(12-n2) = 10-n1
SQRT(1.25)* n2 - n1 = SQRT(1.25)* 12 - 10
1.12 * n2 - n1 ~= 3.42
...which seems remarkably implausible.
