In the biblical Noah's Ark account, what was the ark's stated width?

In the biblical Noah's Ark account, the ark's stated width was 50 cubits.

Genesis 6:15 lists the ark's three dimensions as 300 cubits long, 50 cubits wide, and 30 cubits high. These proportions describe a long, relatively narrow vessel designed to remain afloat, rather than a ship intended for ordinary navigation.

The cubit was an ancient length unit based broadly on the forearm, and its value was not identical everywhere. Modern estimates commonly place the ark's width at roughly 22 to 23 metres, but the exact conversion depends on which cubit standard is used. The biblical text itself does not specify a modern measurement.

The ark also had three decks and rooms or compartments, according to Genesis 6:14–16. Because the narrative supplies dimensions but no detailed construction plan, modern reconstructions necessarily include assumptions about walls, openings, materials, and internal arrangement.
