In Genesis, what was the stated width of Noah’s ark?

In Genesis, the stated width of Noah’s ark is 50 cubits.

The ark’s measurements appear in Genesis 6:15. The verse describes a vessel 300 cubits long, 50 cubits wide, and 30 cubits high. These figures are part of the instructions given to Noah before the Flood in the biblical narrative.

Because the cubit was not a universally fixed modern unit, the width cannot be converted with complete precision. Estimates commonly place 50 cubits at approximately 22 to 23 metres, or around 75 feet, depending on which ancient cubit is assumed. The biblical answer remains 50 cubits.

This measurement is sometimes confused with the ark’s height, which Genesis gives as 30 cubits. It is also distinct from the number of decks: Genesis describes the ark as having lower, second, and third decks, but it does not state their individual dimensions.
