4 mm ruling
4 mm Lined Paper — Printable PDF
Ruled paper with exactly 4 mm (0.157 in) between lines. This page gives the measured line count for every sheet size, shows how 4 mm compares with the named ruling standards and its nearest neighbouring spacings, and provides a print-ready PDF. 4 mm sits just below the 5 mm dot-grid pitch. Workable for very small, careful handwriting or detailed diagrams, but cramped for normal writing.

Capacity
How Many 4 mm Lines Fit on a Page
| Sheet | Dimensions | Rulable height | Lines |
|---|---|---|---|
| A4 | 210 × 297 mm | 267 mm | 66 |
| Letter | 215.9 × 279.4 mm | 249 mm | 62 |
| Legal | 215.9 × 355.6 mm | 326 mm | 81 |
Line pitch is measured centre to centre between adjacent rules, which is how ruled paper is specified. Changing the margin in the generator changes the line count accordingly.

Suitability
Who 4 mm Lined Paper Suits
Four millimetres leaves room for small, controlled handwriting — the handwriting of children in the lower primary grades, of adults who write small deliberately, and of anyone annotating a dense diagram. It is the practical floor for handwriting: tight enough to fit a lot on a sheet, loose enough that an adult hand can stay on the line.
Below 5 mm the practical question is whether the writing is handwriting or annotation. Annotation on a technical drawing benefits from density, because it has to fit alongside the drawing without pushing the scale. Running prose does not — at 4 mm a page holds around 35 lines, which reads as a solid block of text rather than as writing.
If you need a named format instead, dotted paper is the closest match. The full specification table lists every ruling on this site, and the glossary explains the terminology.
