The shiur you use is that of R Chaim Naeh which is widely accepted. It
is far from the largest possible Amah

1. According to Rav Moshe Feinstein, the Amah is 21.25 inches (53.98
centimeters), the Tefach is 3.54 inches (9.00 centimeters), and the
Etzbah is 0.89 inches (2.25 centimeters).

2. According to Rav Chaim Noeh, the Amah is 18.90 inches (48 centimeters),
the Tefach is 3.15 inches (8 centimeters), and the Etzbah is 0.79 inches
(2 centimeters)

3. According to the Chazon Ish, the Amah is 24 inches (60.96 centimeters),
the Tefach is 4 inches (10.16 centimeters), and the Etzbah is 1 inch
(2.54 centimeters).
