What point size should I choose, 0.5mm or 0.7mm?

A 0.7mm tip is the most common everyday choice and balances smooth ink flow with legibility. A 0.5mm extra-fine point (offered on the Pilot Precise V5 and a Pilot G2 variant) suits small handwriting, forms, and detailed work but can feel scratchier on cheaper paper. Most candidates here default to 0.7mm.
