Fishing Reel Line Capacity Calculator

The Fishing Reel Line Capacity calculator helps you determine how much fishing line can be loaded onto a reel when switching line diameter.

Fishing Reel Line Capacity Calculator?

By inputting your current line diameter and length, as well as the new diameter you plan to use, this calculator provides the new potential line length. It's ideal for both beginners and experienced anglers who want to maximize their reel’s efficiency

Key Inputs for the Calculator:

Line Diameter - The thickness of your current fishing line.

Line Length - The length of the fishing line currently on your reel.

New Line Diameter - The diameter of the new line you want to load on your reel.

Formula Used to Calculate the New Line Capacity

If you know the line capacity for a specific line diameter of the fishing reel, you can approximate the new capacity for a different diameter easily.

New Line Length = (Current Line Length*(Current Line Diameter)^2)/New Line Diameter

  • Current Line Diameter = Original line thickness
  • Current Line Length = Length of the original line
  • New Line Diameter = Thickness of the new line
  • Example Calculation

    If you have a fishing reel loaded with a 300-yard, 0.015-inch diameter line and want to switch to a new line with a diameter of 0.010 inches,

    New Line Length = (300 * 0.015^2)/0.010

    New Line Length = 675 yards

    FAQS

    How does line diameter affect reel capacity?

    Line diameter directly impacts how much line can fit on a reel. Thicker lines take up more space, reducing overall capacity, while thinner lines allow for more length.

    Can this calculator be used for any line type?

    Yes, this calculator can be used for monofilament, fluorocarbon, and braided lines.

    Is there an ideal line length for each reel size?

    The ideal line length depends on your fishing style, target species, and reel specifications.
