A clear answer. Here’s how.

Uses the minimum of three width readings and minimum of three height readings per window. Subtracts your total deduction once from each dimension, rejecting non-positive results. Up to 1,000 windows. Supplier conventions differ; this does not choose inside/outside mounting, clearance or a supplier-specific manufacturing size.
