What the grading comes down to
Braided line is made of polyethylene fibre, and the letters PE name that material. The corpus uses them in exactly that sense — « super glattes 8-fach Multifaden PE », « X8 PE-Geflechtschnur ».
The same letters are also used as a grade: PE 0.6, PE 1, PE 2 and upward, a numbering that comes from Japanese line sizing and that European listings reprint. It approximates a thickness band rather than stating a measurement.
Where a European maker prints a PE grade, it almost always prints its own diameter in millimetres beside it. That millimetre figure is the maker’s declaration, and it is the one this site compares.
What it does not promise
It does not promise a diameter. A grade is not a measurement, and two spools at the same grade can differ.
It does not promise a breaking strain, which is declared separately and belongs with the diameter.
It does not promise a section. Braid is woven and not round, and a grade describes it no better than a single diameter does — which is why the strand count appears in nearly every braid title in this corpus, from four-strand to eight.
And it carries no published method. Nobody publishes how a grade is assigned.
Where it shows up on this site
On the braid shelf, where it sits beside the declared diameter and the strand count. It is worth knowing because a reader who has seen PE 1 in one listing and 0,16 mm in another is looking at two different kinds of claim, and the pages say which is which.
It is read alongside the spool length, because braid is sold in 100 m, 150 m and 300 m and a reel needs nylon backing under a short spool.
How it is read here
A page prints the PE grade only where the maker printed it, names it as a grade, and puts the declared diameter and breaking strain beside it. It does not convert a grade into millimetres, and it does not compare two brands on their grades alone.
The questions that keep coming back
Is PE 1 a diameter?
No. It is a grade from a Japanese line-numbering tradition, and European listings usually print it beside their own declared diameter in millimetres. Where both appear, this site prints both and treats the millimetre figure as the maker’s own declaration.
Can I compare PE numbers between brands?
Loosely at best. The grade is a tradition rather than an enforced measurement, and the same PE number from two houses can carry two different diameters and two different strains. The pair of declared figures is the comparison that holds.
Why does the word PE appear at all?
It names the material family — the polyethylene fibre that braided lines are made from. The corpus shows it used that way too: « 8-fach Multifaden PE » and « PE-Geflechtschnur » describe what the line is, not how thick it is.
Which figure should I buy on?
The diameter and the breaking strain, as a pair, plus the strand count. The PE grade is useful for finding the right shelf and not for choosing between two spools on it.
