I forgot where I was discussing this.

"Eerdman’s Dictionary of the Bible

[7, page 1373] states “… archeology

and literature suggests an average

length for the common cubit of

44.5 cm (17.5 in.).” This citation

also gives a range of 42–48 cm

(17–19 in) for the cubit. Range is

an important parameter because it

indicates the variation operating

on this measure. Variation

indicates multiple influences."

A cubit is the size of a human forearm
According to the research done by the Ark Encounter, a 20 inch cubit was used in the building of Noah's Ark. But an 18 inch cubic would give us exactly 1.5 feet which is probably more accurate, since the Ark of the Covenant was also measured in cubits, and the lexicons give it as 18 inches also.

THE ARK OF THE COVENANT
And they shall make an ark of shittim wood: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof, and a cubit and a half the height thereof. (Exod 25:10)

Not certain, but I believe a cubit is one forearm plus a hand breadth.

Since those are mere approximations (and the can vary from person to person), 18 inches would be the best equivalent. Exactly 1.5 feet.

For my own curiosity, I have just measured my own forearm length plus my handbreadth, and here is my results.
(I am 5'8" and fairly normally proportioned in all aspects.

I believe humans have become taller over the centuries, so 1.5 ft. seems inordinate, but I could be way off base.

Gen 6:15b . . the length of the ark shall be three hundred cubits, its width
fifty cubits, and its height thirty cubits.

There was a cubit among the Babylonians, and one in Egypt too. But there
seems to have existed double standards in both countries. Because of that,
there exists no undisputed example of the cubit that remains to the present
time; so the length of the cubit has been variously estimated.

One of the ancient cubits was the length of a man's forearm, from the elbow
to the tip of the middle finger, as is implied from the derivation of the word
in Hebrew and from the Latin cubitum. It seems to be referred to also in
Deut 3:11 as "after the cubit of a man." But that's too vague, and unsuitable
for a scientific standard because not all men's arms are exactly alike.

The Babylonians employed two different cubits: the so-called royal cubit and
the common cubit. From the remains of buildings in Assyria and Babylonia,
the royal cubit is made out to be about 20.6 inches. A cubit of similar length
was used in Egypt. This was probably the cubit mentioned by Ezk 40:5 and
possibly that of Solomon's temple as "cubits after the first measure" (2 Chr
3:3)

The commercial cubit was shorter, and has been variously estimated at
between 16 and 18 inches or more, but the evidence of the Siloam
inscription and of the tombs in Palestine seems to indicate 17.6 inches as
the average length. This was the cubit of six palms, while the longer one
was of seven (Ezk 40:5). The cubit mentioned in Judges 3:16 is from a
different word, the Hebrew gomedh, and was probably shorter.

The cubit of Noah's day remains a total mystery. We have no way of
knowing exactly how long it was. Maybe Noah and his boys passed on their
antediluvian knowledge of weights and measures to the post-flood world and
it stayed pretty close to the original standards over the years; but it's
impossible to know for sure.

NOTE: If we use an 18-inch cubit as a close approximation, then the ark
would have been in the neighborhood of 450' long x 75' wide x 45' high. The
ark's beam was 30 feet wider than its height, so should have proved very
stable, and difficult to capsize even in rough seas-- especially since it had a
flat bottom, which was good too for the purpose intended.

Nothing fancy. Since the ark didn't have to navigate; then it didn't require a
means of propulsion nor was there any practical use for a bow, or a stern, or
a wheel house, a rudder, sails, engine room, anchor, windlasses, or masts--
not even a handrail around the main deck.

Since the ark didn't have to cut through the water like a schooner, then it
didn't need tapered undersides. All the ark really had to do was float. It was
really nothing in the world but a barge: and a very crude barge at that.
Really little more than a very large watertight crate.

Compared to modern ships, 450 feet is not all that big. Oil tankers are
around 1,500, and the Nimitz aircraft carrier is about 1,092 feet. The
distance from home plate to the center field fence in major league baseball,
averages 400 feet or better. So the ark would just about fit into Yankee
stadium. The main playing area of a football field is 300 feet. Add 26 more
for the end zones, and the total is 326; which is still 124 feet short of the
ark's length but at least gives some idea of its scale.

Elbow to fingertip is the customary....and usually based on somebody important.

But it wasn't really that exact and precise....just a rough measurement for most. It could be though....and a cubit on each project was created and replicated precisely. So everything would measure correctly.
