Adult great white sharks usually grow to around 11–16 ft (3.5–5 m), but the largest confirmed individuals reach about 20 ft (6 m) long and over 2,000 kg in weight.

Quick Scoop

  • Most male great whites: about 11–13 ft (3.5–4 m) long.
  • Most female great whites: about 15–16 ft (4.5–5 m) long and noticeably bulkier.
  • Heaviest confirmed individuals: more than 2,000 kg (over 4,400 lb).
  • Credible maximum estimates: around 20–21 ft (about 6–6.4 m) in length.
  • Reported giants over 7–8 m exist, but many of those extreme claims are considered doubtful or heavily revised downward by scientists.

So, in simple terms: great white sharks typically grow to 11–16 ft, and the biggest reliably documented ones are around 20 ft long—absolutely massive apex predators by any standard.
