Nahvalur / Narwhal Fountain Pen Nib Size ComparisonUpdated 10 months ago

For the writing test, I inked each Narwhal fountain pen with Waterman Inspired blue and wrote on Rhodia 80gsm dot grid paper. Each nib was filled from the bottle and tested without any tuning or adjustment.

In evaluating each nib, I focused on three points of concern for pen enthusiasts: line width, smoothness, and ink flow. Results may vary if you use a different ink or paper, apply more or less hand pressure, or due to differing nib manufacturing tolerances. All measurements were taken with a pair of digital calipers and a jeweler's loupe.

Fine point - 0.37mm

Medium point - 0.47mm

Broad point - 0.57mm

Stub - 1.13mm downstroke, 0.37mm horizontal line

Double broad point - 0.66mm
