In the UFC, the bantamweight limit is 135 pounds (61.2 kg).

More specifically:

  • Fighters in UFC bantamweight compete in the 126–135 lb (57–61 kg) range in MMA rules.
  • For UFC title fights at bantamweight, the contracted limit is exactly 135 lb (no extra allowance).
  • For non‑title bantamweight bouts, many commissions allow a 1 lb tolerance (so up to 136 lb on the scale), but the division is still classified as 135 lb.

So if you’re asking “what weight is bantamweight UFC,” the short answer is: it’s the 135 lb (61.2 kg) division.
