The only thing a jig head has to do is reach the strike zone and stay in contact with the bottom. Everything else — brand, paint, eyelet style — is secondary. Depth, wind and current set the number.
The rule of thumb: you want the lightest head that still touches bottom. Too light and you fish above the fish, feeling nothing. Too heavy and the bait drops like a stone, killing the horizontal glide that makes a swimbait look alive.
Find your depth, then pick the calm or windy column. These are starting points for a soft plastic on 10–20 lb braid.
| Depth | Calm / no current | Windy or moving current |
|---|---|---|
| 1–5 ft | 1/16 – 1/8 oz | 1/8 – 3/16 oz |
| 5–10 ft | 1/8 – 3/16 oz | 3/16 – 1/4 oz |
| 10–15 ft | 3/16 – 1/4 oz | 1/4 – 3/8 oz |
| 15–25 ft | 1/4 – 3/8 oz | 3/8 – 1/2 oz |
| 25 ft+ / deep river | 3/8 – 1/2 oz | 1/2 – 1 oz |
Buy a weight assortment before you buy a brand. Having 1/8 through 1/2 oz in the box is worth more than any single premium head.
An assortment lets you follow the chart instead of guessing. Look for a kit with both round-ball and shad-style heads in the 1/8, 3/16, 1/4 and 3/8 oz sizes.

Jig head weight and hook size are separate decisions. A 1/2 oz head with a 2/0 hook is right for a 4 in swimbait; the same head with a 4/0 hook is right for a 6 in bait. The hook gap should be roughly 2.5x the thickness of the plastic where it exits the body.
Use the Jig Head Weight Calculator to convert between ounces and grams for imported heads, and the Hook Size Selector for the hook, and Sinker Weight Converter when you are matching a head to a slip sinker rig.
Depth and current decide the head far more than the fish do. The jig head weight calculator gives the starting number, the lure sink rate calculator turns it into fall speed, and the hook size chart matches the hook to the head.
3/8 oz. It reaches about 15 ft in wind on standard line, casts well on a medium spinning rod, and still glides on the fall rather than dropping straight down. Buy more of that size than any other.
Yes, indirectly. Braid has almost no stretch and is thinner than mono of the same strength, so it sinks faster and transmits bottom contact better. Thinner line lets a lighter head reach the same depth.
Yes, but you can also fish upstream and let the bait swing down naturally. Going one size heavier is the simpler fix; fishing the swing is the more productive one when fish are pressured.
Pick the lightest head that still reaches the bottom and keeps the bait in the strike zone. As a starting point, 1/16 to 1/8 oz covers water under 6 ft, 1/8 to 3/16 oz covers 6 to 12 ft, 1/4 oz handles 12 to 18 ft, and 3/8 oz and heavier is for 18 ft plus or for working fast in current. Add weight when you cannot feel the bottom, not before.
A 3 inch soft plastic usually pairs with a 1/8 to 3/16 oz head and a 2/0 or 3/0 hook, depending on the profile. A bulky paddle tail needs less weight than a slim straight tail, because the tail itself slows the fall. The head also sets the hook gap, so match the hook to the body thickness rather than to the weight alone.
