One of many key decisions you’ll need to make when on the ice, is “what weight line should you use for ice fishing?” The weight line you choose for ice fishing will depend on several factors, including the size and species of fish you’re targeting, the depth of the water you’re fishing in, and the type of lure you’re using. In this article, we’ll explore these factors in more detail and provide some guidance on how to choose the right weight line for your ice fishing needs.
Different types of fishing lines, such as monofilament, fluorocarbon, and braided lines, can all have different weight capacities. So, what weight line should you use for ice fishing depending on fish, water depth, and lure type? Let’s break it down.
Intended Fish Species Affect Ideal Line Weight
To determine the right weight line for ice fishing, you need to consider the species of fish you’re targeting. You also need to know the material of your fishing line, as this will impact which weight you should select. Panfish, kokanee, and trout can be caught using a 3-4 lb monofilament or fluorocarbon line or a 4 lb braided line with a 3-4 lb leader. For walleye and bass, a 6 lb monofilament or fluorocarbon line or an 8 lb braided line with a 6 lb leader is recommended. For lake trout, a 15 lb monofilament or fluorocarbon line or a 10 lb braided line with a 12 lb leader is suggested, while for pike, a 20 lb monofilament or fluorocarbon line or a 20-25 lb braided line with a 20-25 lb leader should be adequate.
Water Depth Matters for Weight of Fishing Line
The depth of the water you’re fishing in will also affect the weight of line you should use. A simple rule of thumb is the deeper the water, the heavier the line you’ll need to get your lure down to the fish. This is because water exerts pressure on the line, making it more difficult to sink.
As a general rule, you’ll want to use a line that’s about 1-2 lb. test per 10 feet of water depth. So, if you’re fishing in 20 feet of water, you’ll want to use a 4-8 lb. test line. If you’re fishing in 40 feet of water, you’ll want to go up to 8-16 lb. test line. However, make sure to take the other factors covered in this guide into account too.
Take Lure Type into Account when Choosing Line Weight

The type of lure you’re using will also affect the weight line you should use. Different lures have different weights and sink rates, so you’ll need to match your line weight to the weight of your lure to ensure that it sinks properly.
As a general rule, you’ll want to use a line that’s slightly heavier than the weight of your lure. So, if you’re using a 1/16 oz. jig, you’ll want to use a 2-4 lb. test line. If you’re using a 1/4 oz. jig, you’ll want to go up to the 6-8 lb. test line. If you’re using a heavier lure like a spoon or a jigging rap, you may need to go up to a 10-12 lb. test line.
Tips for Selecting Weight of Line for Ice Fishing
In addition to these factors, there are a few other best practices to keep in mind when choosing a line weight for ice fishing. Here are a few tips:
- Always check the regulations for the body of water you’re fishing in to make sure you’re using a legal line. Some lakes and rivers have specific rules regarding line weight or material. This isn’t too common, however.
- Consider the weather conditions. If you’re fishing in windy or choppy conditions, you may need to go up in line weight to maintain control of your lure.
- Use a high-quality line that’s appropriate for the conditions. Ice fishing can be tough on lines, so you’ll want to make sure you’re using a line that’s strong, abrasion-resistant, and designed for cold temperatures.
- Don’t be afraid to experiment with different line weights until you find what works best for you. Every angler has their preferences and techniques, so what works for one person may not work for another.
Pick the Correct Weight Line for Ice Fishing
Choosing the right weight line for ice fishing is an important decision that can impact your success on the ice more drastically than you’d expect. Just remember to consider the size and species of fish you’re targeting, the depth of the water you’re fishing in, and the type of lure you’re using when making your decision. Keep in mind where you’re ice fishing, as there could be other geographic factors to consider. As much as it would simplify things, there’s not a “one size fits all” line weight for ice fishing. Don’t be afraid to experiment until you find what works best for you!
