Getting your jig head size right matters more than most people think.
It’s not just about length : body thickness, balance, and hook exposure all play a part.

Here’s a simple guide based on what consistently works.

Smaller profiles

  • 120mm plastics fish best on 3/0–5/0 jig heads
  • Ideal for lighter presentations and finesse situations

Mid-size plastics

  • 150mm plastics pair cleanly with a 7/0
  • Good balance of weight, hook exposure, and swim action

Large plastics

  • 200mm plastics suit a 9/0
  • A solid option for barra when stepping up in profile

Oversize plastics

  • 220–240mm plastics are best rigged on 10/0
  • Designed for thicker bodies and better hook-up rates on bigger fish

Magnum plastics

  • 250–300mm plastics need a 12/0
  • Built for serious fish, deep water, heavy current, and confident bites

If the plastic is thick through the belly, don’t be afraid to size up.
A jig head that’s too small costs hook exposure and missed fish.
