12-inch Burger? Carl’s Jr., Hardee’s Test Market A Foot-Long

The fast-food world has proof positive that size matters: a foot-long cheeseburger.

A cheeseburger sold as a foot-long sandwich, with three burgers and three cheese slices, is being tested at 50 Carl's Jr. restaurants in Southern California and 50 Hardee's units in Indiana. That's the same chain that introduced the world to the 1,400-calorie Monster Burger and the Monster Breakfast Sandwich, with 47 grams of fat.

The Carl's foot-long fetches $4 without lettuce and tomatoes, $4.50 with.

Sonic just added a $2.99 foot-long hot dog this month. Subway, the king of the $5 sub, will roll out a line of spicy foot-longs in mid-August. Quiznos is eyeing a line of premium foot-longs early this fall — one made with prime rib — for $5.

"We live in a society that's fascinated with all things big," says Scott Hume, editor of BurgerBusiness.com, an industry trade site. "It's inherently American to push for something bigger and better than anyone else has."
