Suitability
Who 9 mm Lined Paper Suits
A generous ruling for larger handwriting, younger writers and anyone who annotates between lines. Common in primary education and for writers who find standard ruled paper cramped.
If you need a named format instead, wide ruled paper is the closest match. The full specification table lists every ruling on this site, and the glossary explains the terminology.
