Champaign context
Champaign's growth since its 1855 founding has left window openings across the city that reflect whatever sash sizes and proportions were standard when each home was built, from 19th-century originals to modern manufactured units. That range is why window replacement in the Champaign-Urbana area often starts with matching a home's actual opening, not assuming a standard size.
