There is no magic number — the checker shows your term distribution so you can spot stuffing (same phrase every sentence) or dilution. Natural coverage across headings matters more than any percentage.
Titles display fully up to ~60 characters; descriptions truncate around 155–160. The snippet preview shows exactly where Google cuts each one off.
