Line spacing versus group height
Spacing measures adjacent lines. Four lines make three equal spaces: 3mm spacing gives a 9mm group; 4mm gives a 12mm group. Inner lines are dashed and outer lines solid. Output is blank ruling, without letters or tracing text. Compare a supplied worksheet when a class requires a specific format.
Compare two settings
The buttons set portrait A4, 10mm margins and automatic rows, keeping line color, weight and background. At 3mm, the page fits 20 groups with 4.8mm between groups; at 4mm, it fits 15 with 6.4mm between groups. These are trial settings, not age standards. Try writing a, h and g; increase spacing if cramped.
Why are there fewer rows than requested?
One row means one four-line group. Enter 0 to fill the page automatically, or a smaller integer to limit the count. Usable height limits output: requesting 20 at the 4mm settings above draws 15. It does not shrink spacing or add a second page. Read the actual group count above the preview; adjust spacing, top/bottom margins or orientation to fit more.
Measure one group after printing
Download PDF and print one sheet at Actual size/100%. Measure from the first to fourth line in one group: 9mm at 3mm spacing or 12mm at 4mm. The on-screen preview scales to fit and is not a ruler. For faint lines, darken line color and check ink-saving settings. See print scaling checks or compare handwriting paper types.
