Fishing Hook Sizes – How to Choose the Right Fishing Hook

When it comes to fishing, choosing the right hook size is crucial for success. The size of the hook plays a significant role in determining whether you’ll be able to hook and land your desired catch. In this article, we’ll explore how fishing hook sizes work and provide insights into different hook types for specific fishing scenarios.

How Fishing Hook Sizes Work

Fishing hook sizes can be a bit perplexing for beginners. The sizing system used for fishing hooks may seem counterintuitive, but once you understand it, it becomes much simpler. Hook sizes are denoted by a number (#) or an aught (/) symbol. The smaller the number or aught, the larger the hook size. For example, a #2 hook is larger than a #6 hook, and a 1/0 hook is larger than a 3/0 hook.

Fishing Hook Size (#) and Aught (/)

Understanding the fishing hook size system is essential for choosing the right hook for your fishing needs. The number (#) system is commonly used for larger hooks, while the aught (/) system is typically used for smaller hooks. Both systems provide a way to compare hook sizes across different brands and styles.

The Baitholder Hook is the Best Hook to Get Started Fishing

If you’re new to fishing and looking for a versatile hook, the baitholder hook is an excellent choice. Baitholder hooks feature barbs on the shank that help keep bait securely in place. They are commonly used for bait fishing and work well with a variety of baits, such as worms, minnows, and leeches. Baitholder hooks come in various sizes, typically ranging from #6 to #2, making them suitable for a wide range of fish species.

Octopus Hook for Live Minnows & Leeches

When it comes to using live minnows or leeches as bait, the octopus hook is a popular choice among anglers. Octopus hooks have a unique design with a short shank, wide gap, and inward-facing point. This design allows for excellent bait presentation and increases the chances of a successful hookset. Octopus hooks are available in sizes ranging from #6 to #1/0, making them suitable for various freshwater and saltwater fishing applications.

Aberdeen Hooks for Insects & Removal

If you enjoy fishing with insects or need a hook for catch-and-release fishing, the Aberdeen hook is worth considering. Aberdeen hooks are light wire hooks with a long shank and a slightly offset point. The long shank makes it easier to remove the hook from a fish’s mouth, minimizing potential harm. These hooks are well-suited for fishing with insects, such as crickets and grasshoppers. Aberdeen hooks typically come in sizes ranging from #6 to #2.

Wide Gap Hooks

Wide gap hooks, as the name suggests, have a significantly wider gap between the shank and the point compared to standard hooks. This design allows for better hook penetration and increased holding power. Wide gap hooks are especially effective when fishing with bulky baits or when targeting fish with larger mouths. They are available in various sizes, with sizes between #2 and #5/0 being common for freshwater fishing.


Choosing the right fishing hook size is essential for successful angling. Understanding how hook sizes work, whether denoted by numbers or aughts, helps in selecting the appropriate hook for your fishing needs. Different hook types serve specific purposes, such as the versatile baitholder hook for various bait fishing scenarios. The octopus hook is ideal for live minnows and leeches, while the Aberdeen hook is suitable for insect fishing and easy hook removal. Wide gap hooks provide better hook penetration, and treble hooks offer multiple hook points for dough bait and lure replacements.
