Lure size sets your rod, your line and how deep you can fish it. This is the length-to-weight-to-tackle match, and the species each bracket targets.
| Lure size | Weight | Hook size | Rod power | Line | Targets |
|---|---|---|---|---|---|
| 1.5–2 in | 1/16–1/8 oz | #10 – #8 | Ultralight | 2–4 lb | Panfish, trout in small water |
| 2–3 in | 1/8–1/4 oz | #8 – #6 | Light | 4–6 lb | Trout, crappie, small bass |
| 3–4 in | 1/4–3/8 oz | #4 – #2 | Medium-light | 6–8 lb | Trout, walleye, bass finesse |
| 3.5–4.5 in | 3/8–5/8 oz | #2 – 1/0 | Medium | 8–12 lb | Largemouth and smallmouth bass |
| 4–5 in | 5/8–3/4 oz | 1/0 – 2/0 | Medium-heavy | 12–17 lb | Bass in cover, pike |
| 5–7 in | 3/4–1 1/2 oz | 2/0 – 4/0 | Heavy | 20–30 lb | Pike, muskie, stripers |
| 7–10 in | 1 1/2–3 oz | 4/0 – 8/0 | Extra-heavy | 30–50 lb | Muskie, big pike, saltwater |
Weight ranges overlap because body shape matters as much as length: a compact lipless crankbait weighs far more than a slender soft plastic of the same length.
The lip is what makes a crankbait dive. A longer, wider lip catches more water and drives the bait deeper; a short lip gives a shallow, wide wobble. Line diameter changes it too — thinner line means less drag and more depth.
| Lip type | Typical depth | Use when |
|---|---|---|
| Shallow / square bill | 0–4 ft | Shallow cover, wood, and bouncing off rock |
| Medium diver | 4–10 ft | General purpose over grass and points |
| Deep diver | 10–20 ft | Ledges, humps and the thermocline |
| Extra-deep diver | 20 ft+ | Summer deep structure — needs a heavier rod and thin line |
Two rules cover most mistakes. Cold or clear water, go smaller. Fish are less aggressive and can inspect the bait more closely. Stained water or low light, go bigger. You want a profile they can find and a vibration they can feel.
Then match the forage. If the lake is full of 2-inch shad, a 6-inch swimbait is not cleverer — it is just different from what they are eating. When in doubt, start with something close to the size of the baitfish you can see.
One lure per depth bracket, and you can fish almost any lake.
The one that comes through cover instead of hanging up on it. Fish it around wood and rock in 0 to 4 feet.

Lure packages mix inches, ounces and millimeters. The lure weight calculator checks the weight against your rod, the jig head weight calculator sizes the head that carries it, and the lure sink rate calculator covers fall speed. Panfish, crappie and perch are fish people keep, and the fillet yield calculator has the yield range for each of them.
Three to five inches covers most bass fishing, in the 3/8 to 3/4 oz range, on a medium to medium-heavy rod with 8 to 17 lb line. Go smaller in cold or very clear water and larger in stained water or when targeting big fish.
It depends on the lip and your line. A squarebill runs 0 to 4 feet, a medium diver 4 to 10 feet, a deep diver 10 to 20 feet and an extra-deep diver beyond 20 feet. Thinner line and a slower retrieve both add depth.
Sometimes, but not always. Big lures do filter out small fish, yet big fish often eat small prey and will ignore an oversized bait. Match the size of the local forage first, then go one step up if you only want large fish.
A medium-heavy rod. Lure weight and rod power have to match: too light a rod cannot load properly and you lose distance and accuracy, too heavy a rod will not load at all and you lose feel.
Size and profile first. If the size and action are wrong, color will not save it. Once the size and action are right, color becomes the fine adjustment — natural tones in clear water, brighter or higher-contrast in stained water.
