What was the biblical Ark’s width in cubits, according to Genesis?

According to Genesis, the biblical Ark was 50 cubits wide.

Genesis 6:15 gives three principal dimensions: 300 cubits in length, 50 cubits in breadth, and 30 cubits in height. The breadth is the Ark’s stated width, making 50 cubits the specific answer to this question.

A cubit was an ancient unit based broadly on the length of the forearm, so its exact modern equivalent is uncertain. Estimates often place a biblical cubit around 44 to 52 centimeters, but Genesis itself does not convert the measurement into meters or feet.

The 300-cubit length is much more frequently quoted, which can lead to confusion between the dimensions. The text also says the Ark had three decks. These measurements describe the biblical narrative and should not be treated as a complete modern naval specification.
