Fine Nib, or Medium?

Barrister & Bespoke

Field Guide No. 03 · The Pelikan Brief

Fine Nib, or
Medium?

The stroke width you choose once, and then write with for the next twenty years.


A fountain pen is sold by model and finish. The decision that actually shapes how it feels in your hand is neither. It is the width stamped on the nib itself: Fine or Medium.

Most retailers reduce the choice to a size chart. That is unfortunate. Nib width is the one permanent decision you live with on every page, for as long as you own the pen.

What Actually Changes

Fine Nib Medium Nib
Typical line width ≈ 0.4 mm ≈ 0.5–0.6 mm
Ink flow Sparing and controlled Generous and free-flowing
Feel on the page More textured and precise Smoother and more forgiving
Best paper Smooth stock only — can catch on rough or textured sheets Forgiving of nearly any smooth paper
Best suited for Redlines, marginalia, dense notes, small handwriting Signatures, correspondence, the pen people notice
Without saying it, it says "I take a lot of notes." "I write to be read."

A note on the figures above: nib widths are not standardized across the industry. These follow German convention, which is what Pelikan uses. Japanese houses grind narrower — a Japanese medium sits closer to a German fine — so treat these numbers as describing Pelikan nibs rather than every nib you will encounter.

This guide examines the practical differences between the two, then maps each width to the moments that matter in legal practice — redlining a draft, taking deposition notes, signing closing documents, and writing personal inscriptions.

Exhibit A — The Fine Nib

Built for margins, redlines, and small handwriting.

A fine nib lays down a narrower, more controlled line — roughly 0.4mm at the page. Less ink reaches the paper per stroke, which means less feathering on ordinary copier stock, legible text at a small size, and a slightly firmer, more textured feel as the tip meets the page. It's the nib that disappears into the margin of a draft rather than announcing itself.

It also asks a little more of the hand and the page than a medium nib does. Use a light touch rather than a ballpoint's habitual press — the tip needs less force to lay ink, not more — and keep to smooth, high-quality stock. Rough, laid, or heavily-textured paper can catch a fine tip and interrupt the line entirely, which a broader nib shrugs off.

  • AShoulder — where the nib meets the section and begins to taper. Same anchor point on every width; what happens after this is what changes.
  • BBreather hole — vents air back into the reservoir as ink is drawn out, and stops hairline cracks from creeping up the slit.
  • CSlit — channels ink to the tip by capillary action. Narrower and stiffer on a fine nib, so less ink moves through per stroke.
  • DTipping — the actual writing surface, a hard alloy ball fused to the tip. Ground smaller and rounder than a medium nib's.
Typical line width ≈ 0.4mm
Ink use Sparing — a cartridge lasts longer
Best paper Smooth, high-quality stock — avoid rough or heavily-textured sheets
Technique Light hand, gentle pressure
Best for Redlines, marginalia, dense forms, small handwriting

In Practice

Exhibit B — The Medium Nib

Built for signatures, letters, and the pen people notice.

A medium nib is the width most fountain pen owners settle on for their primary pen — wider than fine, generous with ink, and smoother on the page because more of the tipping's rounded surface is in contact with the paper at once. It's the width that makes handwriting look like handwriting, with the kind of visible ink shading a ballpoint can't produce.

It's also the more forgiving width in practical terms. A medium nib writes reliably under normal pressure and in any direction — no special grip or light touch required — and it handles nearly any smooth, uncoated paper without complaint, which is one reason it's the width most people never think twice about once they've chosen it.

  • AShoulder — the same anchor point as any Pelikan nib; the section grips here regardless of width.
  • BBreather hole — same function as the fine nib's, slightly larger to keep pace with faster ink flow.
  • CSlit — wider-set and more flexible than a fine nib's, moving more ink to the tip with less resistance.
  • DTipping — ground larger and rounder than a fine nib's, which is what puts more of it in contact with the page.
Typical line width ≈ 0.5–0.6mm
Ink use Generous — refills more often
Best paper Forgiving — handles most smooth, uncoated stock without much thought
Technique None needed — writes reliably in any direction, any grip
Best for Signatures, correspondence, the pen you actually reach for

In Practice

The M1000, stocked in medium — the width that makes a signature look written rather than printed.

The Docket

Which one, which moment

Four moments, and the case for each width.

Redlining a draft

Fine Nib

Interlineations and margin notes need a line that doesn't bleed into the text it's correcting.

Case notes / depositions

Fine Nib

Fast, dense, and small — a fine nib keeps up without turning a legal pad into a blot test.

Signing the closing documents

Medium Nib

The one signature on the page people actually look at. Let it show a little ink.

Personal notes & gifting inscriptions

Medium Nib

Warmer on cream cardstock than a fine nib manages — this tier is built for occasions, not to-do lists.

Building the Kit

Four ways in

Every tier is a genuine Pelikan, made in Germany by a house continuously in business since 1838. The difference is nib material, fill mechanism, and how much presence the pen carries on the table.

Three of the four pens below fill by piston rather than cartridge — a mechanism Hungarian engineer Theodor Kovács patented in 19291 and licensed to Pelikan, who brought it to market the same year with a transparent ink window built in from the start2. That patent lapsed decades ago and other makers now build their own piston pens, but the mechanism is unchanged in principle since 1929: it shows you how much ink remains, holds more of it than a cartridge, and refills from any bottle. The exception is the P205, which uses a cartridge instead — part of why it costs and weighs less than the three above it.

Tier I — The Entry

Pelikan P205

Stocked in fine and medium

Steel nib, cartridge-and-converter fill, chrome trim. The lightest of the four and the only one that doesn't fill by piston. This is the pen to buy if you want to find out whether you like writing with a fountain pen before deciding how much you like it.

See the P205

Tier II — The Step Up

Pelikan M200 Marbled

Fine in green-marbled · medium across the collection

The first piston filler in the range, with the ink window that has been part of the design since 1929. Steel nib, gold-plated trim, marbled resin barrel. Most of what makes a Pelikan a Pelikan, well short of the Souverän price.

See the M200

Tier III — The Standard

Pelikan Souverän M800

Fine in black · medium across the collection

Solid 18K gold nib and a brass-sleeved barrel that gives the pen the heft people mean when they say a pen feels serious. If you intend to own one fountain pen for the rest of your practice, this is the one most owners settle on.

See the M800

Tier IV — The Flagship

Pelikan Souverän M1000

Stocked in medium

The largest pen in the range, and the softest nib in it — an 18K nib with noticeably more give underhand than the M800's. Sized for a full grip and long-form writing rather than a shirt pocket.

See the M1000

A Note on Availability

Fine nibs are stocked selectively rather than across the board. The P205 is carried in both widths. The M200 is carried in fine only in green-marbled, the M800 in fine only in black, and the M1000 in medium.

If the Docket above points you toward a fine nib at the senior tiers, write to us before you order. We will tell you what is on hand, what can be brought in, and roughly how long it will take. We would rather special-order the right pen than sell you a width you did not choose.

Exhibit C — Anatomy of a Nib

The detail that decides how a pen feels in ten years.

Steel — standard on the P205 and most M200s, steel nibs are firm and consistent from day one: what you feel at first is close to what you'll feel in year ten, and they're cheaper to produce, which is part of why the entry tiers cost less than the Souveräns above them.

18K gold nib silhouette Illustration of an 18K gold fountain pen nib filled with a warm gold gradient. 18K GOLD NIB

18K gold — standard on the M800 and M1000, gold nibs flex slightly under normal writing pressure and don't corrode, so most owners find one quietly adapts to their hand over time. The nib itself is solid 18K gold — it's the pen's trim (cap bands, clip, rings) that's gold-plated brass.3 Either way, the tipping that actually touches the paper is the same hard tungsten alloy; gold changes the flex, not the wear.

The Argument

The Pelikan Brief

Why Pelikan earned a place in this catalog — the case for the file.

A curated catalog means every item had to earn its place, not just be available. Three grounds are why Pelikan did.

Ground I — Continuity

One house since 1838

Pelikan has been in continuous business since 1838 and built fountain pens since 1929, including piston-fill engineering unchanged in principle across the century since4 (see also notes 1–2, supra). A house that has serviced its own mechanism for a hundred years is a safer long-term bet than one that has changed hands recently.

Ground II — The Nib

Solid gold, verifiably

At its senior tier, Pelikan's nib is solid 18K gold, not a spec-sheet phrase that quietly means something thinner (see note 3, supra) — a claim a skeptical reader can check against the maker's own documentation.

Ground III — The Look

Traditional, on purpose

Pelikan's striped resin barrels and gold nibs were never designed to look modern. They sit in the same traditional register as the leather and brass this catalog is built around — part of the collection, not an accessory bolted onto it.

  1. The 1838 date traces to the Hannover ink and artists' colour works of Carl Hornemann; Günther Wagner acquired the business in 1871 and registered the pelican mark in 1878. The firm's first fountain pen followed in 1929, together with the piston mechanism described in notes 1–2, supra. Ink and artists' materials, not pens, are what the 1838 date refers to.

Closing Argument

A signature is the one piece of handwriting in a legal career that gets read as carefully as it's written — on a closing, a judgment, a partnership agreement. Nib width is a small, permanent decision that shapes every one of them. Choose based on what you're actually writing, not the size chart, and you'll rarely choose wrong.
