(Can you model to two hundredths of an inch?)

The definition works out at 1 to 87 (as near as), or one foot (or one millimetre) on the model represents 87 feet (or 87 mm) in real life.

Six feet = 3/4 of a inch.
Hope this bring a simple solution.

HO scale is roughly one scale foot equals 1/8″ or 3.5 mm.

Hope this helps,

As an example a 6 foot height is 72 inches: 72/87=0.827 inches.
