Genesis specifies that Noah’s Ark had three stories, or decks.
The ark’s dimensions and layout appear in Genesis 6:15–16. After giving its length, width, and height, the passage instructs Noah to make a lower, second, and third deck. The three-level arrangement is therefore part of the textual description rather than a feature invented by modern artists.
The passage also mentions a roof, a side door, and rooms or compartments. Translations differ in how they render some architectural terms, but the three-deck structure is consistently recognized. These details portray the ark as a large, organized vessel intended to hold people, animals, and supplies.
The number is sometimes confused with the ark’s three principal dimensions: 300 cubits long, 50 cubits wide, and 30 cubits high. Those measurements describe size, while three stories describes internal arrangement. The two sets of details answer different questions about the same vessel.
