What this tool does
Ruled paper at the spacing you need. Four presets at 6, 7, 8 and 10 mm, or type any millimetre value for the named rulings that fall between them. Three line weights, three colours, an optional red margin line at an offset you set, and a primary style that adds a dotted midline between each pair of solid lines for early handwriting.

Spacing first, then everything else
Four preset spacings: 6, 7, 8 and 10 millimetres. There is also a custom field that takes any value at all, and that field is what makes the named rulings reachable, because not one of them is a round number.
- Narrow ruled is 6.35 mm, a quarter of an inch, and it is the tightest ruling in common use. Confident small handwriting, and the most lines you will fit on a page.
- College ruled is 7.1 mm, the American secondary and university standard.
- Wide ruled is 8.7 mm. The primary standard in the States, and the right choice anywhere for a child who is still forming letters rather than joining them.
- Primary ruled is 7 mm with the primary style on, adding the dashed midline.
Each of those used to be a separate page here. Now they are a number in a box.
Plain against primary
Plain draws one horizontal line at your spacing, top to bottom. That is what older children want, and adults, for continuous prose or lists or notes.
Primary divides every row into three: a solid top line, a dotted midline halfway down, and a solid baseline. The spacing you choose is the distance between baselines, so each three-line row occupies twice that much vertical space and you get half as many rows on the page. Worth knowing before you print thirty and find they hold six lines of writing.
The dotted midline is doing one specific job: it tells a child where a lowercase a stops and where the ascender of a b keeps going. It is standard in UK Key Stage 1 and in US kindergarten through second grade for exactly that reason.
Weight and colour are accessibility settings
Light is 0.3 point, medium 0.5, dark 0.8. Light saves ink and suits pencil work where a heavy rule competes with the writing. Dark is not a preference, it is what a child with a visual impairment needs in order to see the line at all.
Blue is the classroom standard. Grey is subtle enough for a journal and it photocopies cleanest of the three, which matters if the sheet is going to be duplicated. Green is gentler over a long writing session, and some readers find it noticeably easier on the eye than either.
The margin line is optional, always red, and sits wherever you put it. Twenty-five millimetres by default, or 32 for college ruled, 28 for narrow, 24 for wide, or off entirely.
A Year 2 handwriting sheet
Eight millimetre spacing, medium weight, blue, margin line at 25 mm, primary style on.
That draws a solid top line, a dotted midline at four millimetres, and a solid baseline, repeating down the page. A model sentence goes at the top of each copy. The children keep a, e and o between the midline and the baseline, and let b, d and h reach the top line, which is the whole lesson made visible on the paper rather than explained at the front.
What it will not do
- No headers. No footers, and no text fields, so write those on by hand or overlay them elsewhere.
- Spacing is uniform down the whole page, so you cannot mix a band of 10 mm rows with a band of 7 mm rows on one sheet.
- The margin line is vertical, red, and singular.
- The primary midline has a fixed dot spacing that cannot be adjusted.
- Horizontal rules only. Graph paper, music staves and calligraphy guides are separate tools on this site.
FAQs
Quick answers
What line spacing should I use for different age groups?
Use 10 mm for Reception and Year 1 (ages 4-6) or kindergarten and first grade, where large spacing supports early letter formation. Switch to 8 mm for Years 2-3 (ages 6-8) as fine motor control improves. Use 7 mm for upper primary (ages 8-11) and 6 mm for secondary students and adults who want compact, efficient note-taking space.
What is primary-ruled paper and when do I need it?
Primary-ruled paper has three lines per row: a solid top line, a dotted midline, and a solid baseline. The dotted midline helps young children control the height of lowercase letters and understand where ascenders (like b, d, h) and descenders (like g, p, y) belong. Use this style for handwriting instruction in early primary or elementary grades; switch to plain ruled paper once pupils write confidently without the midline guide.
Can I adjust the margin line position?
Yes. Tick the margin line option and enter your preferred offset in millimetres. The default is 25 mm from the left edge, which suits standard hole-punch spacing in UK and European binders. US Letter users often choose 31.75 mm (1.25 inches) to match three-hole punch standards.
Which line weight should I choose to save ink?
Light line weight (0.3 pt) uses the least ink and suits pencil work or personal note-taking. Medium (0.5 pt) balances visibility and cost, and is the most common choice for classroom worksheets. Dark (0.8 pt) improves contrast for pupils with visual impairments or when photocopying multiple generations of a master sheet.
How many lines fit on an A4 or US Letter page?
The number of lines depends on your spacing and ruling style. Plain ruled paper at 8 mm spacing yields approximately 30-32 lines on A4 and 28-30 lines on US Letter. Primary-ruled paper at 8 mm baseline spacing (each row is 16 mm tall) yields approximately 15-16 rows on A4 and 14-15 rows on US Letter.
Can I enter a custom line spacing not listed in the dropdown?
Yes. The generator accepts a custom line spacing in millimetres, overriding the preset 6, 7, 8, or 10 mm options. Enter any value between 5 mm and 15 mm to match a specific handwriting scheme or create specialist layouts for occupational therapy or calligraphy practice.
Why choose grey or green lines instead of blue?
Blue is the traditional classroom standard and matches most commercial lined paper. Grey offers a softer, less intrusive contrast for personal journals or long writing sessions. Green reduces glare when viewing scanned or photographed lined paper on screens, and some users with dyslexia or visual processing differences find green easier to read against.
