Berkley Trilene 100% Fluorocarbon
Diameter chart, reel capacity & backing guide
US package-label reference for 10, 15, and 20 lb Trilene 100% Fluorocarbon. The 10 lb evidence is a 2000 yd bulk spool; the 15 and 20 lb evidence is for 200 yd filler spools. These are exact pictured packages, not a complete strength range or a guarantee about every production run.

Full-spool fluorocarbon or a measured working length?
Berkley identifies this as 100% PVDF main line, distinct from fluorocarbon-coated nylon and its separate leader products. The verified 15 and 20 lb filler options are .015 and .017 in; check reel capacity before choosing them for a small spool. Backing can reserve the documented fluorocarbon for the working portion, provided the connection stays beyond the line you need to fish.
Berkley 100% Fluorocarbon diameter chart
US manufacturer-label evidence only: TF2010-15 at 10 lb/2000 yd, TLFFS15-15 at 15 lb/200 yd, and TLFFS20-15 at 20 lb/200 yd. Both diameter units are printed independently on each label. Other strengths and package combinations are intentionally omitted; these photographs do not establish stock availability.
| Strength | Inches | mm | Spools (yd) |
|---|---|---|---|
| 10 lb | 0.012 | 0.300 | 2000 |
| 15 lb | 0.015 | 0.380 | 200 |
| 20 lb | 0.017 | 0.430 | 200 |
Choosing your Trilene 100% Fluorocarbon strength
The documented 10 lb bulk spool is .012 in/.30 mm and contains 2000 yd. That is a bulk supply for planned fills, not an instruction to put the whole package on one reel.
The 15 lb filler label prints .015 in/.38 mm and 200 yd. Compare that diameter with the reel's rating when planning a baitcasting fill or a shorter working length over backing.
The 20 lb filler label prints .017 in/.43 mm and 200 yd. Its larger cross-section leaves less line on a given spool than the .015 in option; choose within the rod, lure, and reel requirements.
No numeric estimate is offered here for the remaining strengths simply because they appear in a store selector. The exact diameter and package must both be documented.
This is a source-based specification and setup guide, not a hands-on performance or aging test.

Separate bulk supply from reel fill
The 10 lb row documents 2000 yd, while the 15 and 20 lb rows document 200 yd. Measure each working length and keep the remaining line with its original strength and model identification.
Budget the working length
Leave enough fluorocarbon for casting, fish movement, and later trimming. When using backing, account for that working length before filling the remaining spool space.
Keep main line and leader identities separate
A short section used as a leader does not turn this product into Berkley's dedicated leader formulation. Do not substitute ProSpec, Vanish, Trilene XL Fluorocarbon, or a coated line's numbers into this chart.
Trilene 100% Fluorocarbon questions, answered
Berkley specifies a proprietary 100% PVDF formula for Trilene 100% Fluorocarbon. This page is for that mainline product, not fluorocarbon-coated nylon.
Why are only 10, 15, and 20 lb included?Those are the strengths for which the inspected manufacturer package labels provide exact diameters and lengths. The current official selector lists more strengths but leaves diameter metadata blank.
Why is the 10 lb package 2000 yd?The verified photograph is the TF2010-15 bulk spool, SAP 1564072. A 200 yd filler package is a separate package identity and is not inferred from that bulk label.
Are the retailer diameter tables being used as the source?No. For 15 and 20 lb, the source is the manufacturer's printing on the actual spool pictured by the retailer. The printed model codes and SAP numbers match official Berkley US records.
Why do the inch and metric numbers not convert perfectly?Both are separately printed rounded label values. This chart preserves them; capacity calculations use the published inch diameter rather than replacing it with a conversion of the rounded metric field.
