Number Line Generator
Evenly spaced, exactly labelled number lines for teaching — integers, decimals or true stacked fractions. Print at size or download a 150 DPI PNG.
Every value v is placed at left + (v − start) ÷ (end − start) × width, so the spacing cannot drift. Print at 100% with “fit to page” off — the sheet is exactly 210.0 × 297.0 mm.
Range & step
Active step 1 · 11 ticks per line
Switching this off clamps the range to 0 and above; it stays on by default so a negative start reaches below zero.

Layout

About this tool
This generator draws printable number lines to scale: set a start, end and tick step, then choose integers, decimals or true stacked fractions in lowest terms, with major and minor ticks, blank student lines and up to twelve lines per sheet. Every value is placed with a single proportion — left + (v − start) ÷ (end − start) × width — so the spacing never drifts, and a label that would collide with its neighbour is rotated or dropped instead of overprinted, with a note above telling you when that happens. Sheets are rendered at 150 DPI against a real A4 or US Letter page, and everything runs locally in your browser.
