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

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

Genesis 6:15 gives the ark’s dimensions as 300 cubits in length, 50 cubits in width, and 30 cubits in height. These measurements are part of the instructions Noah receives before constructing the vessel. Genesis does not define the cubit in modern units, so converting the height into feet or metres requires an external estimate.

A cubit was an ancient unit based broadly on the length of a forearm, but actual standards varied. For that reason, proposed modern heights differ according to which cubit is used. The unconverted biblical figure is the most certain answer.

The 30-cubit height also corresponds to the ark’s three decks, with Genesis 6:16 listing lower, second, and third levels. The text does not state that each deck was exactly 10 cubits high; that would be an assumption because structural space, floors, and roof design are not specified.
