⚠ 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.

### How Many 3/8 in Lines Fit on a Page

_Ruled lines per sheet at 3/8 in spacing, allowing a 15 mm margin top and bottom._

| Sheet | Dimensions | Rulable height | Lines |
| --- | --- | --- | --- |
| A4 | 210 × 297 mm | 267 mm | 28 |
| Letter | 215.9 × 279.4 mm | 249 mm | 26 |

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.
