Fly Tying Bead Reference Guide
Fly tying beads play a major role in how a fly sinks, balances, and fishes. Bead material, size, shape, and style all affect weight, profile, and performance. This guide explains the most common types of fly tying beads and how to choose the right option for nymphs, jig flies, and streamers.
This reference is designed to work alongside our fly tying materials and bead collections, helping tiers make informed choices at the vise.

Bead materials
The material a bead is made from determines its weight and how quickly a fly sinks.
Tungsten beads
Tungsten beads are significantly heavier than other bead types of the same size. They are commonly used for Euro nymphs, Perdigons, and fast-sinking nymph patterns where getting down quickly is important.
Brass beads
Brass beads offer moderate weight and are a versatile option for traditional nymphs and wet flies. They are often more affordable and work well when less weight is needed.
Glass and specialty beads
Glass beads and other specialty materials are lighter and are typically used for aesthetic purposes, subtle weight, or specific traditional patterns.
Bead shapes and styles
Countersunk beads
Countersunk beads have a tapered hole that allows the bead to sit flush against the hook eye. These are commonly used on standard nymph hooks.
Slotted beads
Slotted beads are designed to fit jig hooks. The slot allows the bead to slide back over the angled hook eye, helping the fly ride hook point up.
Coneheads and specialty heads
Coneheads add weight and create a smooth, tapered profile for streamers and larger patterns. They are commonly used on woolly buggers, leeches, and baitfish imitations.
Fly tying bead sizing explained
Fly tying beads are typically sized in millimeters (mm). Larger bead sizes add more weight and bulk to a fly.
| Bead size (mm) | Common uses |
|---|---|
| 2.0–2.4 mm | Small nymphs, midges |
| 2.8–3.2 mm | Standard trout nymphs |
| 3.5–3.8 mm | Larger nymphs, stoneflies |
| 4.0 mm+ | Large nymphs, streamers, jig flies |
This chart is a general guideline. Hook size, wire diameter, and bead hole size all influence final fit.
Matching beads to hooks
Choosing the right bead requires matching the bead hole size to the hook wire and eye shape.
- Standard nymph hooks typically pair with countersunk beads
- Jig hooks require slotted beads
- Heavier wire hooks may need a larger bead hole
- Smaller hooks often require down-sizing bead diameter to maintain proportions
Test-fitting beads on hooks before tying helps avoid clearance issues at the hook eye.
Choosing beads by fly type
- Euro nymphs and Perdigons: tungsten slotted beads for maximum sink rate
- Traditional nymphs: brass or tungsten countersunk beads
- Wet flies: brass or glass beads for subtle weight
- Streamers: coneheads or larger beads for profile and movement
Beads for beginner fly tiers
New fly tiers do not need a large selection of beads to get started. A small, versatile range will cover most patterns.
- Brass countersunk beads in 2.8 mm and 3.2 mm
- Tungsten countersunk beads in 2.8 mm or 3.0 mm
- Slotted tungsten beads for jig hooks (optional)
Starting with these basics allows tiers to experiment with weight and balance before expanding into specialty bead styles.
Common bead selection mistakes
- Using beads that are too large for the hook size
- Choosing countersunk beads for jig hooks
- Over-weighting flies for shallow water
- Ignoring bead hole size relative to hook wire
Balancing bead size, hook choice, and pattern style leads to better sink rates and more effective flies.
