Side-by-Side Comparison Binders & Hole Punching

ISO 838 (4-Hole) vs. Japanese Multi-Hole (JIS)

Comparing 2 standards across 11 specifications. 11 key differences identified.

Comparing:
ISO 838 (4-Hole)
Japanese Multi-Hole (JIS)

The ISO 838 4-Hole extension (commonly known in Europe as the '888' format) specifies four holes spaced at three consecutive 80.0 mm intervals (80–80–80 mm, spanning 240.0 mm total) with standard 6.0 mm hole diameters. It is standard for heavy A4 4-ring presentation binders and archival document protectors to prevent page sagging.

The Japanese Loose-Leaf standard (governed by JIS P 0138) specifies a fine multi-hole grid with an exact 9.5 mm (3/8 inch) pitch and 5.5 mm hole diameter, featuring 26 holes for B5 paper and 30 holes for A4 paper. Engineered by stationery manufacturers such as Kokuyo and Maruman, it eliminates paper tear-out entirely.
