Unlocking the Secrets of the Fly Size Chart: Your Ultimate Guide to Fly Fishing Success

Ever felt lost at the tackle shop, staring at rows of colourful flies and a fly size chart? You’re not alone! Figuring out how to know what flies to use can seem challenging. But don’t worry, young angler! This guide will decode fly size charts for you. It will also teach you how to choose the right flies that catch fish!

Fly Size Chart: Demystifying Tiny Numbers

Fly sizes are like secret codes! Bigger numbers mean smaller flies. Most charts list sizes for dry flies (which float on top), nymphs (which live underwater), and streamers (which look like baitfish).

How to Know What Flies to Use: It’s All About the Food!

Imagine a picky eater fish. What would it want for lunch? That’s the key to fly selection! Here’s what matters:

  • Fish Menu: Trout love insects! Choose flies that look like what’s hatching on the water.
  • Seasonal Treats: Different insects hatch at different times of year. Spring means small flies, and summer brings bigger ones.
  • Water World: Fast water needs heavier flies to sink. Clear water calls for flies with realistic colours.

Matching the Hatch: Fly Fishing Fashion Show

Imagine tiny mayflies dancing on the water. That’s a “hatch”! Use a dry fly resembling those mayflies to tempt the trout.

Tip: Start with a few general flies in sizes 14-16 for nymphs and dry flies. You can always add more later! It’s also recommended to consult with local fly shops or experienced anglers in your area. Personalized recommendations that consider current conditions and the specific body of water can increase your chances of success in fishing.

Bonus Round: Common Fly Fishing FAQs

Q: How do you Know What Fly to Use to Catch Trout?

A: The most common answer to “How do you know what fly to use to catch trout?” revolves around understanding what the trout are feeding on and choosing a fly that imitates that food source. Here’s a breakdown of the key points:

1. Match the Hatch:

  • This is the primary strategy for selecting successful flies. It involves understanding what insects are hatching on the water (the “hatch”) and choosing a fly that resembles those insects in size, colour, and shape.

2. Consider Seasonal Variations:

  • Different insects hatch at different times of the year. Smaller flies are typically used in early spring when insects are smaller. In comparison, larger flies might be more suitable in late summer or fall.

3. Observe Water Conditions:

  • Water flow, clarity, and temperature can influence fly selection.
    • Faster water might require heavier flies (larger size) to sink effectively. In comparison, slower water might call for lighter flies (smaller size) to maintain a natural drift.
    • Clearer water might favour natural colours, while murkier water might benefit from brighter colours for better visibility.

4. Start with Versatile Options:

  • For beginners, starting with a few general-purpose flies in standard sizes, like 14-16 for nymphs and dry flies, is helpful. These can cover a range of insects and water conditions.

Remember, experimentation is essential. Observe the water, see what insects are present, and try different flies to see what works best on your fishing trip.

Q: What’s the most successful fly for trout?

A: Unfortunately, there isn’t a single definitive answer to the question “What is the most successful fly for trout?” due to several factors:

  • Variety of Trout Species: Trout species have different preferences and feeding habits.
  • Seasonal Variations: Insects that trout feed on change throughout the year, requiring different fly imitations.
  • Water Conditions: Factors like water flow, temperature, and clarity can influence fly selection.
  • Presentation: Even the “perfect” fly won’t catch fish if not presented properly.

However, while there isn’t a single “best” fly, there are some popular and versatile options that often prove successful across various situations for trout:

  • Nymphs: Beadhead Pheasant Tail, Hare’s Ear Nymph, Prince Nymph
  • Dry Flies: Adams, Parachute Adams, Elk Hair Caddis, Blue Dun

These flies are widely available, imitate common food sources for trout, and are relatively easy to fish. However, experimentation and local knowledge are vital to finding the most successful flies for your specific fishing conditions.

Q: What’s the best all-around fly size for trout?

A: With the fly size chart in hand, choosing becomes clearer. Knowing what flies to use is key. The “best all-around size” varies, but often it’s sizes 14-16. This range suits nymphs and dry flies best. These are top picks for trout.

Here’s why sizes 14-16 are commonly recommended as an all-around option:

  • Versatility: They cover a good range of insect sizes that trout typically feed on.
  • Visibility: They are visible enough for anglers and fish in most water conditions.
  • Presentation: They are generally a manageable size for casting and presenting effectively.

However, it’s crucial to remember that adjusting the size based on specific conditions is vital.

Q: What colour fly catches the most trout?

A: While anglers often debate the “best” colour for trout flies, the most common answer in search results is that no single colour guarantees the most success. Trout vision allows them to see a wide range of colours, and their preference can vary depending on several factors:

  • Natural Colours: Flies that imitate the natural colours of the insects trout feed on (e.g., browns, olives, blacks) are often a good starting point.
  • Water Conditions: Natural colours might be more effective in clear water, whereas brighter colours can sometimes be more visible in murky water.
  • Hatch Matching: When trying to match a specific insect hatch, using a fly that closely resembles the colour of the hatching insect is crucial.
  • Experimentation: Ultimately, the best colour often comes down to experimentation and observing what works best on your specific fishing trip.

However, the most common tip from the fly fishing chart is to go for darker colours like black, blue, and violet when the light is dim, or you’re fishing deep. Wondering how to know what flies to use? Look at the chart! It shows chartreuse and white or red and white as top picks for any light. They stand out the most. And because it pops against the backdrop, black is the go-to colour in most situations, especially effective at night.

Remember: The best fly is the one that looks most like the food the fish are eating!

Bonus Q: What tippet size and diameter should be used per fly size for fish of what size?

A: The most common answer to the question “What tippet size and tippet diameter should be used per fly size for what size fish?” emphasizes a balance between several factors:

  • Fly Size: Generally, a tippet size should be one-third the size of the fly. For example, if you’re using a size 14 dry fly, a 4X tippet (around 0.007 inches diameter) might be suitable.
  • Target Fish Size: You’ll need a stronger tippet to handle the fight for larger fish. However, a very thick tippet can be unnatural and spook fish.
  • Water Conditions: Faster-moving water requires a heavier tippet to avoid getting swept away. Conversely, calmer water allows for a lighter tippet for better presentation.
  • Knot Strength: Ensure the tippet chosen allows for strong knots that can hold the weight of the fish.

Here’s a breakdown of common tippet size ranges based on fly size:

  • Large Flies (Size 8 and above): 0X – 3X (thicker for larger fish and stronger currents)
  • Medium Flies (Size 10-16): 4X – 5X (most versatile range for trout fishing)
  • Small Flies (Size 18 and below): 6X – 7X (thinnest for delicate presentations)

Important points to remember:

  • This is a general guide, and adjustments might be necessary based on specific situations.
  • Always consult a local fly shop or experienced angler for recommendations based on your target species and fishing conditions.
  • Consider the breaking strength of the tippet in relation to the size of fish you expect to catch.
  • Balance is essential: Choose a strong tippet to land the fish while remaining thin enough for a natural presentation.

With this fly size chart, picking the right fly becomes easier. Knowing what flies to use boosts your chances. You’re on the path to fly fishing success now! Keep practicing, try out various flies, and enjoy exploring fly fishing’s vast world!
