In Genesis, how wide was Noah’s Ark?

In Genesis, Noah’s Ark was 50 cubits wide.

Genesis 6:15 specifies the Ark’s main dimensions as 300 cubits long, 50 cubits wide, and 30 cubits high. The biblical text uses the ancient cubit, a unit generally based on the length of an adult’s forearm, so its exact modern equivalent is uncertain.

The width is one part of a three-number specification rather than a modern engineering measurement. Depending on which cubit length is assumed, 50 cubits is often estimated at roughly 22 to 26 metres, but the text itself does not provide a metre or foot conversion.

Readers sometimes remember only the Ark’s length because 300 cubits is the most frequently quoted dimension. Width and height are separate figures, and changing the assumed cubit affects modern estimates without changing the biblical numbers.
