What were the biblical dimensions of Noah’s Ark in cubits: length, width, and height?
Answer
300 by 50 by 30 cubits
The biblical dimensions of Noah’s Ark were 300 by 50 by 30 cubits: length, width, and height. Genesis 6:15 gives these three measurements in its construction instructions.
A cubit was an ancient unit based broadly on the length of the forearm, so its exact value varied by culture and period. Using a common estimate of about 45 centimeters, the Ark would be roughly 135 meters long, 22.5 meters wide, and 13.5 meters high. Modern conversions are therefore approximations.
The proportions produce a long, broad, relatively low vessel. Naval engineers and historians have sometimes noted that such proportions would favor stability, though the biblical account does not describe the Ark as a maneuverable ship.
The figures are often confused with measurements from later traditions or modern replicas. The canonical Genesis numbers are specifically 300, 50, and 30 cubits.
