What was the width of Noah's Ark in the Genesis account?
Answer
50 cubits
The width of Noah's Ark was 50 cubits in the Genesis account.
Genesis 6:15 gives a compact set of dimensions: 300 cubits long, 50 cubits wide, and 30 cubits high. These figures describe the ark as much longer than it was wide or tall.
The answer is expressed in cubits because Genesis uses an ancient measurement system. Since historical cubits differed in length, modern conversions are approximate rather than exact. The text itself is certain about the numerical proportion, even when the modern equivalent is debated.
The width is sometimes confused with the ark's height, which Genesis gives as 30 cubits. Remembering the dimensions as 300–50–30, in length, width, and height, keeps the three figures distinct.
