The nib-size cheat sheet

One page that ends the Japanese-vs-Western confusion forever.

EFFMBBB1.1JAPANESE F ≈ WESTERN EF
  • True-width strokes for EF → BB and the 1.1 stub, side by side
  • The Japanese ↔ Western translation table (F ≈ EF, and why)
  • A quick matcher: handwriting size + paper → the nib to order
  • The four grinds — round, stub, italic, architect — at a glance

Join the desk letter and we’ll email the sheet, plus one considered letter a week. No noise, no spam.

One considered letter a week. No noise, no spam.
