What was the stated height of Noah’s Ark in Genesis?

The stated height of Noah’s Ark in Genesis was 30 cubits.

Genesis 6:15 records the Ark as 300 cubits long, 50 cubits wide, and 30 cubits high. The instructions also mention three decks, which means the height was not simply the height of one open boat interior. The text does not provide a detailed engineering plan for dividing the decks.

Because ancient cubits differed in length, 30 cubits is usually converted only approximately, often to around 13 or 14 metres. The biblical number is more reliable than any single modern conversion. It also should not be confused with the dimensions of later models or with measurements claimed for alleged Ark-shaped geological formations.

The proportions create a vessel far longer than it is high, which would favor stability in rough water. Naval engineers have sometimes discussed that shape as a hypothetical barge design, but such calculations do not establish that the biblical vessel existed as a recoverable archaeological object.
