According to Genesis, Noah’s Ark had three levels.
Genesis 6:16 tells Noah to make the ark with lower, second, and third decks. These instructions describe a multi-level vessel designed to contain Noah’s family, animals, and supplies. The passage also mentions a window or opening, a door in the side, and compartments within the ark.
The three levels are separate from the ark’s dimensions. Genesis gives its length as 300 cubits, its width as 50 cubits, and its height as 30 cubits. Because the biblical cubit has no universally fixed modern length, exact metric conversions vary, but the proportions are clear in the text.
Popular illustrations often show the ark as a large boat with several decks, but Genesis provides only limited architectural detail. It does not specify the exact number or arrangement of individual stalls, rooms, or ramps beyond the broad construction instructions.
