How Large Was Noah’s Ark?

"The length of the ark shall be three hundred cubits, its width fifty cubits, and its height thirty cubits." (Genesis 6:15)

Unlike many whimsical drawings that depict the Ark as some kind of overgrown houseboat (with giraffes sticking out the top), the Ark described in the Bible was a huge vessel. Not until the late 1800s was a ship built that exceeded the capacity of Noah’s Ark.

The dimensions of the Ark are convincing for two reasons: the proportions are like that of a modern cargo ship, and it is about as large as a wooden ship can be built. The cubit gives us a good indication of size.¹ With the cubit’s measurement, we know that the Ark must have been at least 450 feet (137 m) long, 75 feet (23 m) wide, and 45 feet (14 m) high. In the Western world, wooden sailing ships never got much longer than about 330 feet (100 m), yet the ancient Greeks built vessels at least this size 2,000 years earlier. China built huge wooden ships in the 1400s that may have been as large as the Ark. The biblical Ark is one of the largest wooden ships of all time—a mid-sized cargo ship by today’s standards.

1. The cubit was defined as the length of the forearm from elbow to fingertip. Ancient cubits vary anywhere from 17.5 inches (45 cm) to 22 inches (56 cm), the longer sizes dominating the major ancient constructions. Despite this, even a conservative 18 inch (46 cm) cubit describes a sizeable vessel.
