Number Line Generator
Print number lines for any range and interval, with labels on every Nth tick.
What is Number Lines?
A number line is a straight line with evenly spaced ticks representing numbers, used for counting, comparing, rounding, adding and subtracting, and for introducing negative numbers and decimals. Teachers print strips of them for repeated practice.
How it works
Ticks are generated from the real range and interval, so a 0–20 line by 1s has exactly 21 ticks and a 0–1 line by 0.1s exactly 11. Labels are placed on every N-th tick so a fine interval stays readable, and the lines are stacked evenly down the page — several per block, several blocks per sheet.
