How to Choose the Right Cast Net Size

The most common cast net question we get: "What size do I need?" Most people overthink it. This guide explains the measurements, the trade-offs, and gives you a clear recommendation based on what and where you're fishing.
Radius vs. diameter — what the size actually means
Cast nets are measured by radius— the distance from the center horn to the lead line at one edge. When a net is listed as "10 ft," that means it opens into a circle 20 ft across (10 ft diameter on each side of center).
This trips up a lot of buyers. A 10 ft net sounds smaller than it is. In water, fully open, it covers an area of about 314 square feet. That's a significant circle.
The real question: what's your experience level?
Net size is partly about where you fish and what you're catching — but mostly about whether you can throw it. A bigger net is harder to throw cleanly. If it doesn't open fully because you can't handle the weight, it's worse than a smaller net that opens perfectly every time.
| Radius | Best for | Experience |
|---|---|---|
| 3–5 ft | Kids, kayaks, very small bait | Beginner |
| 5–6 ft | Most freshwater fishing, wading | Beginner–Intermediate |
| 8 ft | Saltwater, bridges, docks | Intermediate |
| 10 ft | Experienced casters, open water | Experienced |
| 12 ft | Professional / commercial | Expert |
If you're new to cast nets, start with a 6 ft. It's the most forgiving size to learn on, covers more water than you'd think, and is available in every series. Once your throw is consistent, step up to an 8 ft.
Mesh size — the number that matters for what you catch
Mesh size controls which bait stays in the net vs. slips through. Smaller fish need smaller mesh openings.
- 1/4" mesh — Glass minnows, mud minnows, spearing, baby mullet. Fine mesh that catches almost everything but has more water resistance.
- 3/8" mesh — The all-purpose choice. Mullet, shad, menhaden, pilchards, shiners. If you're not sure, get 3/8".
- 1/2" mesh — Bigger bait: croaker, spot, large mullet. Faster sink rate.
- 5/8" mesh — Jumbo mullet, menhaden, large threadfin. Very open — small bait escapes immediately.
For general freshwater and inshore saltwater fishing, 3/8" is the right call 80% of the time. The BasicGear Basic, Sports, and Classic series all come in 3/8" as the default option.
Sinker weight per foot — why it matters
Cast nets are rated in pounds per foot of radius. This tells you how fast the net sinks and how tightly it closes on the bottom.
BasicGear Basic and Sports: 3/4 lb/ft. Standard weight — good for most freshwater and calm saltwater fishing.
BasicGear Classic: 0.75–1 lb/ft with pure lead sinkers. The lead is denser, so it sinks faster for the same weight. In current or deeper water, the Classic gets to depth before bait schools scatter.
The practical rule: calm, shallow water → standard weight is fine. Current, depth, or fast-moving saltwater bait → go heavier.
What series should I buy?
BasicGear Basic Series — most people start here
Zinc iron sinkers, monofilament nylon mesh, available in all sizes and mesh options. Best all-around value. If you're not sure what you need, this is the right starting point.
BasicGear Sports Series — if you fish from a boat
Identical to the Basic in every way except the sinkers are PVC-coated. That coating protects fiberglass hulls and aluminum gunnels from scratching. If you throw from a boat, this is worth the small price difference.
BasicGear Classic Series — for current and depth
Pure lead sinkers mean a faster sink rate. Ideal for fishing from bridges, piers in tidal current, or any situation where you need the net to hit bottom quickly.
BasicGear Pancake Series — professional grade
Designed for maximum opening radius on each throw. Available in Gold and Blue variants. Harder to throw than the other series — this is a net for experienced casters who know what they want.
Our recommendation for most anglers
Start with a BasicGear Basic Series, 6 ft radius, 3/8" mesh. It's the best all-around net for someone learning to throw or fishing mixed freshwater/inshore environments. Upgrade to an 8 ft or the Classic Series once you've got consistent technique.
