In Genesis, what was the height of Noah’s Ark in cubits?

In Genesis, Noah’s Ark was thirty cubits high.

Genesis 6:15 gives the Ark’s three principal measurements as 300 cubits long, 50 cubits wide, and 30 cubits high. The height is one of the text’s explicit dimensions and is distinct from the Ark’s length and width.

A cubit was an ancient unit based broadly on the length of a forearm, but its exact value varied by culture and period. As a result, modern conversions are estimates rather than perfectly fixed measurements. The biblical text itself gives the dimension in cubits, not in meters or feet.

The stated proportions produce a long, rectangular vessel rather than the boat shape commonly shown in paintings. The Genesis description also says the Ark had three decks, making the height relevant to its internal arrangement.
