What was the Ark’s width in the dimensions given by Genesis?

Genesis gives Noah’s Ark a width of 50 cubits. In the same set of measurements, the vessel is 300 cubits long and 30 cubits high.

These dimensions appear in Genesis 6:15 as part of God’s instructions to Noah. Since the ancient cubit was not a universally fixed modern unit, the width cannot be converted with complete precision. Depending on the standard used, 50 cubits is often estimated at roughly 22 to 26 metres.

The proportions make the Ark six times as long as it is wide and ten times as long as it is high. This has led commentators and naval writers to describe the biblical vessel as a stable, box-like craft designed for capacity rather than speed or manoeuvrability.

Readers sometimes swap the three numbers because they are presented together. The easiest distinction is that 300 is the length, 50 is the width, and 30 is the height.
