In Genesis, how high above the ark was its window in Noah’s Ark?

In Genesis, the window of Noah’s Ark was one cubit high above the ark’s roof or structure, depending on translation.

Genesis 6:16 includes a difficult architectural phrase often translated as making a window and finishing the ark “to a cubit above.” Many English versions understand this as a window or opening associated with a one-cubit measurement. The text does not provide a modern-style diagram of its exact design.

Because the Hebrew wording is unusual, translations differ in how they describe the feature. Some say Noah made a window, while others refer to an opening or a source of light. The number itself is generally rendered as one cubit.

This detail should not be confused with the ark’s total height, which Genesis gives as 30 cubits. The one-cubit measurement belongs to the window or upper opening instruction, not to the vessel’s overall elevation.
