How to Tie Fishing Line Onto a Reel: A Step-by-Step Guide for Beginners

Updated November 2026

Learning how to tie fishing line onto a reel takes about five minutes once you know the method, and it is the first skill every new angler needs. In this guide you will attach line to the spool with an arbor knot, fill the spool evenly, and set up a reel that casts smoothly and holds up under a fish. The steps below work for most spinning and baitcasting reels.

What You Need Before You Start

Gather a few basics before you touch the spool. Having everything ready keeps the line from twisting and saves you from redoing the setup.

• A spool of fishing line rated for the reel’s line capacity (check the rating printed on the spool or reel body)
• Scissors or line clippers
• A pencil or dowel to hold the spool while you wind
• A pair of gloves or a towel for grip if the line is slippery

How to Tie Fishing Line Onto a Reel with an Arbor Knot

The arbor knot is the standard way to attach line to a reel spool. It grips the spool core firmly and holds under the pressure of a hooked fish.

1. Pass about 6 inches of line around the bare spool core, then tie a simple overhand knot around the standing line.
2. Tie a second overhand knot around the standing line, pulling it snug against the first.
3. Wrap the tag end around the spool core at least three times, then pass it through the loop you made in step one.
4. Moisten the knot with water or saliva, then pull the standing line and tag end slowly to tighten everything against the spool.
5. Trim the tag end close, leaving about 1/8 inch so it does not slip.

Spooling the Line Correctly

Once the knot is secure, the way you fill the spool affects casting distance and how much trouble you will have with tangles later.

Keep tension on the line as you wind. Use a pencil through the spool center and have a helper hold the spool, or place it in a line spooler. Stop when the spool is filled to about 1/8 inch from the lip. Overfilling causes the line to jump off during casts, and underfilling reduces casting distance.

Setting Line Tension on a Spinning Reel

On a spinning reel, wind the line onto the spool with the bail closed and the line guided evenly across the spool. Avoid letting the line loop or twist as it goes on, because twists are a common source of later tangles.

Setting Line Tension on a Baitcasting Reel

On a baitcasting reel, turn the spool by hand while holding the line with light pressure from your thumb. Wind slowly and evenly so the line lays flat, and avoid overfilling the spool.

Common Mistakes to Avoid

• Skipping the moistening step, which can let the knot slip under load.
• Trimming the tag end too close, which can allow the knot to work loose.
• Winding with no tension, which leads to loose coils and bird’s nests.
• Filling the spool past the lip, which causes line to spill during casts.
• Using line heavier or lighter than the reel’s rated range, which affects drag and casting performance.

Recommended Gear

A line spooler keeps tension steady while you fill the reel, which makes even winding much easier for beginners. View on Amazon

FAQ

Can I use a regular overhand knot to attach line to a reel?

A plain overhand knot can slip on the spool core under load. The arbor knot grips the core better and is the method most anglers use for this job.

How much line should I put on a reel?

Fill the spool to about 1/8 inch from the lip, and match the line weight to the reel’s rated capacity. Check the manufacturer’s label on the reel for guidance.

Why does my line keep twisting while I spool it?

Twists usually come from spooling without tension or from line that has been stored coiled. Keep steady pressure on the line and let the spool turn evenly as you wind.

Conclusion

Tying line to a reel with an arbor knot takes only a few minutes and gives you a secure base for every cast. Fill the spool evenly with steady tension, and stop short of the lip. Once your reel is set up, you are ready to start fishing.
