Define the programme, not only the hall size
A college training centre, school sports hall and university tournament venue have different priorities. The same building could support basketball, badminton, volleyball, physical education and assemblies.
Agree which activities have priority, which are occasional, how the building is occupied throughout the day and what equipment must move between modes.
Document the teaching and recreation schedule as well as the sports list. A venue used primarily for school physical education may need a different storage and maintenance solution from one used regularly for competitive fixtures.
