What was the width of Noah’s Ark in the Genesis dimensions?

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

Genesis 6:15 presents the Ark’s three principal dimensions in a set order: 300 cubits long, 50 cubits wide, and 30 cubits high. Since the length is six times the width, the description portrays an unusually elongated, box-like vessel. Converting cubits into modern units is approximate because ancient cubits were not perfectly standardized.

The width matters when comparing the Ark with modern reconstructions. Many replicas choose a particular cubit length and then reproduce the biblical ratio, while others make artistic changes for structural or visitor-access reasons. The biblical text itself gives the width only in cubits.

This figure is sometimes confused with the Ark’s height, which Genesis gives as 30 cubits. It is also separate from the measurements of Noah’s family, the animals, or the later dimensions assigned to other legendary flood vessels.
