In combat sports, “light heavyweight” usually means athletes in the mid‑170s to around 205 pounds, but the exact number depends on the sport and organization.

Here’s the quick breakdown:

Boxing (pro & amateur)

  • Professional boxing: light heavyweight is 175 lb (79 kg) limit – fighters must not exceed 175 lb at weigh‑in.
  • Olympic/ amateur boxing: typically over 76 kg but under 80 kg (about 167.5–176.4 lb).

MMA (UFC and others)

  • UFC: the light heavyweight limit is 205 lb (93 kg) ; the class effectively runs from 186 to 205 lb because middleweight ends at 185 lb.
  • Many athletic commissions define the light heavyweight cap around 205–206 lb (93 kg).

Kickboxing

  • General range: often 77–95 kg (171–210 lb).
  • Example: one major ruleset defines light heavyweight as 172.1–179 lb (78.3–81.4 kg).

Simple way to think about it

  • Boxing: think “175‑pounders.”
  • MMA (UFC): think “205‑pounders.”
  • Kickboxing: think “upper‑170s to around 200+ lb , depending on the promotion.”

So if you’re asking “what weight is light heavyweight?” the answer is:

  • Around 175 lb in boxing ,
  • Around 205 lb in MMA (like UFC) ,
    with kickboxing sitting in a similar but slightly broader band depending on the organization.
