3 mm ruling
3 mm Lined Paper — Printable PDF
Ruled paper with exactly 3 mm (0.118 in) between lines. This page gives the measured line count for every sheet size, shows how 3 mm compares with the named ruling standards and its nearest neighbouring spacings, and provides a print-ready PDF. 3 mm is tighter than the 5 mm dotted default. Used for detailed technical sketching and dense reference notes rather than running handwriting.

Capacity
How Many 3 mm Lines Fit on a Page
| Sheet | Dimensions | Rulable height | Lines |
|---|---|---|---|
| A4 | 210 × 297 mm | 267 mm | 89 |
| Letter | 215.9 × 279.4 mm | 249 mm | 83 |
| Legal | 215.9 × 355.6 mm | 326 mm | 108 |
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.
In context
3 mm Compared With Standard Rulings
| Format | Pitch | Relative to 3 mm | Lines / A4 |
|---|---|---|---|
| Narrow Ruled | 6.0 mm | 3 mm wider | 44 |
| Dotted | 5.0 mm | 2 mm wider | 53 |
| Reporter Notebook | 6.0 mm | 3 mm wider | 44 |
3 mm is tighter than the 5 mm dotted default. Used for detailed technical sketching and dense reference notes rather than running handwriting.
Nearby spacings
3 mm vs the Closest Other Spacings
3 mm vs 2 mm: a 1 mm difference, tighter — 44 more lines per A4 sheet than 3 mm.
| Spacing | Pitch | Relative to 3 mm | Lines / A4 |
|---|---|---|---|
| 2 mm lined paper | 2 mm | 1 mm tighter | 133 (44 more than 3 mm) |
| 4 mm lined paper | 4 mm | 1 mm wider | 66 (23 fewer than 3 mm) |
| 5 mm lined paper | 5 mm | 2 mm wider | 53 (36 fewer than 3 mm) |
Suitability
Who 3 mm Lined Paper Suits
At this pitch there is very little room for a normal adult hand. It suits ledgers, indexes, annotation margins and anyone deliberately writing small. Descenders will collide with the line below unless handwriting is unusually compact.
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.
