Lined Paper Generator
Ruled paper at exactly the spacing you need.
Lighter lines use less ink and are easier to draw over. Under about 0.15 mm some inkjets drop the line entirely, so check one page before printing a stack.
How the Lined Paper Generator works
Lined paper sounds like the least necessary thing to generate until a school specifies 8 mm ruling, or a child needs wider lines than any pad in the shop sells, or you want margins on both sides for annotation. Set the ruling in millimetres and it prints at that ruling.

The rulings that have names, and what they measure
American stationery has three standard rulings and they are worth knowing by number rather than by name. Wide ruled, also called legal ruled, is 8.7 mm between lines and is what primary schools use. College ruled, sometimes medium ruled, is 7.1 mm and fits roughly four extra lines on a page. Narrow ruled is 6.35 mm, a quarter inch, and turns up mostly in pocket notebooks.
British and European exercise books do not use those names. School books are usually ruled at 8 mm, with 6 mm and 7 mm appearing in secondary and 10 to 12 mm in infant classes. French seyès ruling is a different animal entirely, with a horizontal every 2 mm and heavier lines every 8, designed for teaching cursive letterforms with precise ascender and descender heights.
None of this is standardised in any binding sense, which is why a school specifying a ruling is doing something useful and why being able to set a number rather than pick from a menu solves the problem outright.
Choosing a ruling for a child learning to write
The instinct to give a young child narrow lines because it looks neater is backwards. Fine motor control develops from large movements to small, so a child whose letters are naturally two centimetres tall will produce cramped, effortful writing on 8 mm ruling and comfortable, legible writing on 15 mm.
A reasonable progression is 15 mm at four to five years, 12 mm at five to six, 10 mm at six to seven, and 8 mm from around seven or eight once letterforms are settled and joins are being taught. Move down when the writing looks small for the space rather than on a schedule, because the range across children of the same age is enormous.
The other thing that helps more than ruling width is line contrast. A child copying letters benefits from a clearly visible baseline, so a slightly darker and heavier line than an adult would choose is the right call. Push the weight to 0.4 mm and use a mid grey or light blue rather than near-white.
What this tool does not draw
There is no red vertical margin rule. Exercise books have one and it is genuinely useful for marking and for date columns, but it is not offered here, and it is better to know that before printing forty sheets. Drawing it in with a ruler on the master before photocopying is the low-technology answer and takes about a minute.
There are no dotted midlines or descender guides either, the four-line ruling used for handwriting instruction where a dashed line marks the x-height and a lower line marks where descenders stop. That is a genuinely different ruling and worth having; it is simply not this one.
What it does do that most printed pads cannot is let you set the ruling to an arbitrary number and adjust the margin independently. If the requirement is 9 mm ruling with a 25 mm top margin on A5, no shop stocks it and this makes it in about ten seconds.
Where the lines land, and why the last one looks wrong
Lines are drawn at exact intervals starting one interval below the top margin and continuing until the bottom margin is reached. That means the spacing is guaranteed correct and the gap at the foot of the page is whatever is left over, which is rarely a whole interval.
On A4 at 8 mm ruling with 10 mm margins the usable height is 277 mm, which gives thirty-four lines and leaves 5 mm spare. That last strip looks like a mistake and is not; it is arithmetic. If it bothers you, nudging the top margin by two or three millimetres usually redistributes it into a tidier gap.
The alternative approach, stretching the spacing slightly so lines divide the page evenly, is what a lot of generators do and it is the wrong trade. It means the ruling is no longer the number you asked for, which defeats the purpose of asking for a number.
Uses that are not schoolwork
Letter writing, oddly, is one of the most common. Good writing paper is unruled, and a ruled sheet slipped underneath as a guide is the traditional solution. Print a sheet at your natural writing size with heavy dark lines and it shows through decent paper clearly enough to write straight without ruling the letter itself.
Music practice notation, lyric writing, and songwriting all want wider spacing than standard ruling so that chords can go above the words. Twelve to fifteen millimetres with light lines works well.
Language learners studying scripts with different height conventions benefit from setting the ruling to match. Arabic and Devanagari sit differently on a baseline than Latin script does, and a ruling chosen for English handwriting fights them. Being able to set the number means you can match whatever your textbook uses rather than adapting to whatever the pad was sold at.
Frequently asked questions
What is wide ruled and college ruled?
Wide ruled is 8.7 mm between lines, the American standard for primary school. College ruled is 7.1 mm, which fits about four more lines on a page and is what most secondary and university notebooks use. UK exercise books typically run 8 mm.
What spacing suits a child learning to write?
Start wide. Reception and Year 1 handwriting usually needs 12 to 15 mm, dropping to around 10 mm as letterforms settle and 8 mm by the time joined writing is fluent. Going narrower before a child is ready produces cramped letters rather than neat ones.
Can I add a margin line?
The margin setting controls the white space around the ruling, but it does not draw the red vertical rule that exercise books use. That is worth knowing before you print a stack expecting one.
Why does the last line sit oddly close to the bottom?
Because lines are drawn at exact intervals from the top margin down, and the page height rarely divides evenly by your ruling. Nudging the margin up or down by a millimetre or two usually lands it where you want.
Is this good for practising calligraphy?
For basic spacing, yes. Proper calligraphy practice wants slant guides and an x-height ruling in addition to the baseline, which plain ruled paper does not give you. Set a tight spacing and treat every third line as your baseline as a workaround.
