Sometimes one size doesn't fit all. On Tuesday, McDonald's (NYSE:MCD) revealed a new lineup for its iconic Big Mac burger that includes both a smaller -- and much bigger -- version of the meal.

Beginning March 11, fast-food fans will have the option of ordering a "Little Mac," which includes less beef and bread. Hungrier fans of the venerable burger brand can buy a "Double Big Mac," which features four patties -- twice the beef.

The chain celebrated the 50th anniversary of the Big Mac last year and this limited-time offer is part of that commemoration. There are likely more innovations like this on the way, too. "We're not done with the Big Mac love just yet and can't wait to show you what's next," the company said in a press release.

McDonald's recently closed the books on an unusually strong fiscal year as its global growth rate hit a 10-year high. But customer traffic is still trending lower in the U.S. market, and management is hoping that menu innovations can help flip that trend back into positive territory. Today's Big Mac announcement fits in with that strategy to drive more fast-food visits and higher average spending in its home market.
