Ruled paper with exactly 4 mm (0.157 in) between lines.

⚠ Print at 100% — not “Fit to Page”

Your PDF reader's default print scaling shrinks the sheet by a few percent, which changes the real line pitch. In the print dialog, set scaling to **100%** or **Actual Size** so the measurements on this page match what comes out of the printer.

Capacity

### How Many 4 mm Lines Fit on a Page

_Ruled lines per sheet at 4 mm spacing, allowing a 15 mm margin top and bottom._

| 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

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](https://linedpaperpdf.com/dotted-paper-pdf/) is the closest match.
