Our report about how restaurant dinner plates have grown from 9" in the 1960s to 12" today grabbed a lot of attention. With so much extra room on our plates, many restaurants are filling up that extra space with more food. The food is relatively cheap, but not necessarily good for us.
We did our math wrong and were too conservative with our initial estimates of how much extra space. Many viewers reminded us that 3" more space on a round plate = 78 percent more space. (We reported that it was a 33 percent increase -- we forgot to use the simple middle school math formula a = pi * r2).
Seventy-eight percent more food -- talk about a mouth-full!
