The chain is launching a "Mac Jr" and a "Grand Mac" nationwide for a limited time in early 2017, the company said Thursday.
The Mac Jr. is a miniature version of the Big Mac with a single 1/6-pound burger patty.
The Grand Mac features 66% more beef than the regular Big Mac, an extra slice of cheese, and a larger bun.
The regular Big Mac has two 1/10-pound burger patties, three pieces of bread, and two slices of cheese, special sauce, lettuce, pickles, and onions.
"The Big Mac is a legend and a great-tasting burger with hints of pickle relish, mustard, garlic and onions," McDonalds Chef Mike Haracz said in a statement. "We listened to our customers who told us they wanted different ways to enjoy the one-of-a-kind Big Mac taste. The classic combination of ingredients remains timeless and customers around the world continue to enjoy its signature taste."
Some customers will be able to try to burgers in advance of the national rollout. They will be available in Florida and the Pittsburgh area beginning in mid-November.
