Retail sales of pizza pans grew 7% in the 12 months ending March 2011, compared to the same time last year, signaling a consumer trend towards making pizzas at home, according to The NPD Group.

Metal pizza pans accounted for 64% of dollar sales during the 12-month period, according to NPD’s Retail Tracking Service. Stoneware/clay stone pizza pans, the second largest product segment, are outpacing sales of metal pans, however, with a 21% growth.
