Ball lightning objects have been reported to vary from pea-sized to several meters in diameter.
Notes on verification
Multiple independent sources (Science Notes, Discover Magazine, USPTO patent filing, local science columns) corroborate the pea-to-several-meters size range, consistent with Wikipedia's description.
