Generator · Print-true
Printable lined paper, ruled to the real standards
Pick college, wide, or narrow rule at its true stationery measurement (7.14, 8.73, or 6.35 mm), or a 3-line handwriting practice rule with a dashed midline. The sheet is drawn as vector geometry in your browser and sized in real millimeters, with no watermarks or sign-ups, and nothing is uploaded. Print it on paper or save it as a PDF from the same dialog.

How this generator works
The sheet you see is an SVG drawn in physical units, and every rule sits at a real millimeter coordinate. The presets load the US stationery standards: college rule at 7.14 mm (9/32 in), wide at 8.73 mm (11/32 in) and narrow at 6.35 mm (1/4 in). The page computes how many whole rows fit inside the printable area (the sheet minus your margin) and centers them so the rules never crowd an edge; college rule on US Letter gives 35 rows, and the guide to ruled paper sizes and lines per page lists the count for each rule on Letter and A4. The handwriting preset switches to repeating three-line groups (solid top line, dashed midline, solid baseline, then a gap of half the rule height) and fits as many whole groups as the content area holds. The optional left margin line lands at 31.75 mm (1.25 in) from the sheet edge, the standard stationery margin, and prints in light red whatever line color you pick. The handwriting preset draws the 1/2 inch rule, the same ruling the handwriting worksheets generator uses at its default size, so a worksheet with letters to trace and blank practice paper from here match at that size. That generator's other three rulings are larger and have no preset here.
When you print, leave the dialog's scale at 100% or "Actual size"; check that setting once and it stays checked. "Fit to page" rescales the whole sheet, and a 7.14 mm college rule then arrives at 6.7 mm. This page sets the print size to match your chosen sheet exactly and keeps the rules inside a 12.7 mm default margin, which clears the mechanical dead zone of essentially every consumer printer, so nothing needs rescaling. At 100% the millimeters on paper match the millimeters on the readout; the methodology page shows how to check that with a ruler.
Line weights below about 0.2 mm can print unevenly on consumer printers, which is why the default is 0.3 mm. Borderless edge-to-edge rules depend on printer hardware this page can't control, so the margin control stops at 5 mm.
