How to spool a spinning reel
Put fresh line on a spinning reel so it lies firm and even, sits at the right depth, and casts without looping.

What this skill is for
How line sits on the spool decides almost everything downstream: casting distance, tangles, and how honestly your drag reads. Line wound under tension casts in tight loops; line wound loose coils off the spool in springs that turn into bird's nests on the first good cast.
What you need
- Spinning reel and rod
- New spool of line
- Line clippers or small scissors
- A box or your feet to brace the line spool
- A damp cloth for tension
Step by step
- 01
Check how much you need
Most reels print a line capacity on the spool. Fill to just below the spool lip — a little less rather than a little more — and start with the amount your line's diameter suggests for that capacity.
- 02
Brace the supply spool
Stand the new line spool on the floor with the label facing up so the line comes off the top, or squeeze it between your feet. It must spin freely as line comes off; if it stutters, tension is going into the line and you will put a curl into it.
- 03
Tie the line to the spool
An arbor knot is the standard: an overhand around the spool arbor, then a second overhand around the standing end, moistened and pulled tight so the first knot slides down against the spool. Trim the tag end close.
- 04
Wind with steady tension
Clip the reel onto the rod, open the bail and wind by the handle at an even pace. Pinch the line through the damp cloth in your other hand — firm, constant pressure, enough to feel it, not enough to stretch the line.
- 05
Fill to the right depth
Stop when the line sits a millimetre or two below the spool lip. Overfilled line throws loops the moment the bail opens; underfilled line rubs the spool edge, loses distance, and makes your drag weaker than the line's rating.
- 06
Clip, tie on and settle it
Cut the line, tie on the lure or lead you'll fish with, and make a dozen gentle casts to bed the new line down. Check the depth again after that and top up if it has settled.
Where it goes wrong
- Filling above the spool lip — the classic cause of overruns and tangles.
- Winding with no tension, which leaves soft, spongy layers that coil off in springs.
- Letting a smooth spool run bare under braid, which can spin under load; back it with monofilament or a strip of tape first.
- Tightening an arbor knot dry, which heats and weakens monofilament.

Filling above the spool lip — the classic cause of overruns and tangles.
How do I know spool a spinning reel is done correctly?
The spool feels firm under a thumb, the line lies flat across the whole width, and it sits just under the lip rather than level with or above it.
