Reel Line Capacity Calculator
How many meters of line fit, by gauge
Reel Line Capacity
Enter the reel's "○号-○m" spec and the gauge you want to spool for the resulting length.
Capacity
0 m
※ Assuming constant line volume, capacity is inversely proportional to gauge (length = spec length × spec gauge ÷ target gauge). Real results vary with braid and backing.
Capacity by gauge
⚠️ This calculator is a reference tool based on the standard line/sinker specifications (gauge-to-diameter) established in Japan and also used in Korea, plus publicly available conversion data. Real products vary in diameter, strength (lb) and weight for the same gauge depending on material (nylon, fluorocarbon, PE braid), maker, number of braided strands (4/8) and coating, so results may differ from the product label. PE braid lb ratings in particular vary widely by maker, so treat them as a range and always check the product label for exact values. calcstool.com assumes no liability for tackle choices, equipment damage, accidents or fishing outcomes based on these results.
FAQ
How do I know meters on a reel?
The reel spec gives a basis like "2号-150m". For another gauge, assuming equal line volume, capacity = spec length × spec gauge ÷ target gauge. e.g. a 2号-150m spool holds ~100m of 3号.
Why does thicker line spool less?
Thicker line takes more volume per wrap, so less length fits — capacity is inversely proportional to gauge.
Is it exact?
It is theoretical. Braid, backing, tension and spool shape cause differences, so use it as a guide.
