How Do You Size a Fly Fishing Hook?

Fly fishing hooks come in all shapes and sizes, but the most important factor when sizing a hook is the size of the fish you are Targeting. Knowing what size hook to use can be a challenge, especially for beginners. To help anglers make the right choice, we have put together this guide on how to size a fly fishing hook.

Step 1: Determine the Species of Fish

The first step in sizing a fly fishing hook is knowing what species of fish you are Targeting. Different species of fish require different sizes and styles of hooks. Knowing what type of fish you are trying to catch will help you determine which size and style of hook is best for that situation.

Step 2: Consider the Size of Fish

Once you know what species of fish you are Targeting, consider the size range that they typically grow to. For example, if you are Targeting small panfish like bluegills or sunfish, then smaller hooks in the 12-16 range would be best. But if you are Targeting larger fish like bass or trout, then larger hooks in the 8-10 range would be more appropriate.

Step 3: Consider Hook Style

The third step is to consider what style of hook is best for your situation. Different styles have different characteristics that make them better suited for certain types of fishing.

For example, single hooks tend to be best for dry flies while double hooks are better for streamers or nymphs. There are also offset hooks and barbless hooks which can be useful depending on your situation.

Step 4: Select Your Hook

Once you have determined the species, size and style of hook that is appropriate for your situation, it’s time to select your hook. There are many manufacturers who produce quality fly fishing hooks so it’s important to do some research before making your selection. Make sure that you select a quality hook with sharp points and strong metal so that it won’t bend or break when taking larger fish.


: Sizing a fly fishing hook correctly can make a big difference in your success when out on the water. By determining what species of fish you are Targeting, considering their typical size range and selecting an appropriate style and size of hook, anglers can ensure they have the right tools for successful fishing trips!
