McDonald’s now has a solution for Goldilockean carnivores long dissatisfied with the one-size-fits-all nature of the Big Mac.

Meet the Little Mac and the Double Big Mac, two new versions of the classic menu item with different dimensions but all the same ingredients you know, love, and sing about: all-beef patties, Special Sauce, lettuce, cheese, pickles, and onions on a sesame seed bun. And they're available for a limited time now at certain locations.

If your eyes tend to be bigger than your stomach, you may want to opt for the Little Mac, which is really only little when compared to its father burger. Without the Big Mac’s customary second beef patty and extra layer of bun, the Little Mac is essentially a regular-sized burger.

If you’re so hungry you could eat a bear (or you’re looking for a burger big enough to actually feed one), spring for the Double Big Mac, a Brobdingnagian fast food feat with a whopping total of four beef patties. However, it doesn’t include an additional layer of cheese to maintain the ideal meat-to-dairy ratio—so you could either ask the drive-through attendant for an extra slice, or make use of the Kraft Single you keep in your wallet at all times.

As Food & Wine reports, it’s not the first time McDonald’s has introduced altered burgers into the Big Mac family. Back in 2016, it released both the Mac Jr., a single-layer version with a bigger patty, and the Grand Mac, an all-around larger burger with the same ingredient ratio as the original Big Mac. Since the Little Mac and the Double Big Mac only comprise items that McDonald’s kitchens already keep in stock, it’s likely easier for franchises to accommodate these menu changes.

Before you drive off to enjoy your perfectly-portioned meal, the workers want you to check to make sure they really did get it just right—find out 13 other secrets of McDonald’s employees here.
