There are a lot of soft plastic worms out there, and I’ve caught fish on just about every size — from teeny-tiny to absolutely massive. They all have their time and place. But does your worm size actually matter to the fish? I ran a two-day, as-scientific-as-I-could-make-it test — the smallest worm I own against one of the biggest — to find out. Here’s what the bass told me.

How I Set Up the Comparison
The matchup was a 4-inch stick bait against a 10-inch Strike King Zeus worm — about as small-versus-big as my box gets. To keep it fair, I alternated in blocks of roughly 10 casts with each worm, back and forth, fishing the same laydowns and cover so each bait saw the same water. I ran it over two different days on two different fisheries so the result wasn’t just one body of water’s preference.
One variable I deliberately controlled: the weight. The small worm got a 3/16-ounce and the big worm a quarter-ounce, because the big curly tail has more resistance on the fall. I wanted both to sink at close to the same rate so I was testing size, not fall speed. You can’t keep everything identical on the water, but over an hour-plus of casting the averages even out.
When you compare two different soft plastics, don’t just pin the same weight to both. A bulkier bait or a bigger tail falls slower on the same weight. Bump the weight up slightly on the bigger, higher-resistance bait so both baits fall at the same rate — then you’re actually testing the thing you care about.
What the Bass Actually Did
Day one (fishing sticks and laydowns on a river): the small worm took the numbers, 5 to 2, in a short one-hour window — and it even grabbed the biggest fish of that session, a solid chunk. Surprising, since I’d gone in expecting the big worm to shine around that wood.
Day two (a big North Texas lake, fishing around flooded timber): the small worm kept piling up numbers — it ended something like 15 to 5 overall for sheer bite count. But the big worm did the one thing that actually matters to a lot of anglers: my buddy Kevin stuck a true giant on the 10-inch Zeus — right around a 9-pounder — plus a couple of other quality three-pound-class fish. The small worm never produced anything close to that size.
Across both days the pattern was clear: the small worm got far more bites, and the big worm got the bigger bites. The size of the worm correlated with the size of the fish. If you want numbers, go small. If you’re hunting one kicker, go big.
| Worm | Bite Count | Fish Size | Best Use |
|---|---|---|---|
| 4-inch stick bait | Won big (numbers) | Mostly smaller, average fish | Getting bit, pressured water, tough days |
| 10-inch Zeus worm | Fewer bites | Produced the giants (up to ~9 lb) | Hunting a big-bite kicker |
Why “It Depends” Is the Honest Answer
If you’ve watched my Tackle Time comparisons before, you know the answer to almost every “which is better” question is it depends on your situation. Can a smaller worm catch bigger fish sometimes? Absolutely — especially on pressured water, or when the presentation changes. A small worm on a drop shot or a shaky head, or dragged behind a Carolina rig instead of a traditional Texas rig, is a totally different deal than what I tested here.
So there’s rarely a hard yes-or-no in fishing — same as asking whether scent matters. But here’s where my confidence lands after two days: in these two scenarios, shallow wood and deeper wood, the size of the fish tracked the size of the worm. When I’m specifically going for bigger-than-average bass, I’ll reach for the bigger worm the vast majority of the time. When I just want to get bit, the little stick bait is tough to beat. Your experience may differ — that’s fishing.
What I Was Throwing
Both worms were on a 7-foot medium-heavy flipping-and-pitching setup (really anything 7-foot to 7-foot-3 works), with strong 17-to-20-pound Seaguar InvizX fluorocarbon — you could tell from how often I horsed fish out of the trees that it holds up. My hook picks: the VMC Redline hybrid worm hook in a 3/0 for big worms and a smaller version for the little stick bait.
Whatever size worm you throw, let it fall on a slack line. After the cast, peel a little line out so the worm drops straight down and looks the most natural — and you get the longest retrieve back to you. The moment you flip the bail or click the spool, the line tightens and the worm pendulums toward you, which is rarely what you want.
Final Thoughts
Does worm size matter? Based on two days and a whole lot of bass: yes — but not in a one-size-wins way. Small worms got the numbers; big worms got the giants. Tie both on, let the fish tell you what they want that day, and lean bigger when you’re specifically hunting a kicker. There are a dozen more variables we could test — rig, scent, color, fall rate — and that’s exactly why fishing is never a flat yes or no.
