Easy. We often use idioms for comparisons.

One old way would be: “Trump and Hitler are both 2/3 yards from one piece” which means “They’re cut from the same (bad) fabric”.

Fabric was cut in an old measurement"alen" which was 2 foot or 2/3 yards, so simply stating the length would be understood as fabric, similar to how everyone knows that a 2x4s is a piece of wood and such.
