Free Graph Paper Generator
Choose a grid, dots, ruled lines or isometric paper, set the spacing in mm or inches, and download it as a PDF.
What is a Graph Paper Generator?
Graph paper is paper printed with a regular pattern of lines or dots, used for maths, sketching, knitting charts, floor plans and handwriting. This generator prints square grids, dot grids, ruled lines and isometric grids at the spacing you choose, centred on Letter or A4 paper.
Set the spacing in millimetres or inches, including fractions such as 1/4in, and add heavier major lines every few squares for engineering-style paper. The pattern fills the page inside the margin with whole squares, centred so the edges are even, and the preview shows the exact page the PDF will print.
Key Features
Four Patterns
Square grid, dot grid, ruled lines and an isometric grid of triangles.
Metric or Imperial
Spacing in millimetres, decimal inches or fractions such as 1/4in.
Major Lines
A heavier line every 4, 5 or 10 squares, as on engineering and metric paper.
Even Edges
Whole squares only, centred on the page, so nothing is cut off at one side.
Several Sheets
Print up to 20 identical pages in one PDF.
Perfect for everyone
- Students
- Teachers
- Engineers
- Designers
- Crafters and bullet journal fans
How to Use the Graph Paper Generator
Use the menus above the text box, or type the settings yourself, one per line. The preview and the check update as you change anything, so you can try spacings until the page looks right before you download, and keep the text to make the same paper again later.
Pick a Pattern
Square grid, dots, ruled lines or isometric.
Set the Spacing
Choose a preset or type your own, such as 7mm or 3/8in.
Add Major Lines
For a grid, add a heavier line every few squares.
Download and Print

Graph Paper Specs, Checked
Each row is a graph paper spec of the kind people print for school, work and craft, from metric engineering paper to college-ruled lines. Each answer is this tool’s check: the pattern, the page and how many squares, lines or dots fit.
“pattern: grid spacing: 5mm major: 5 shade: medium paper: a4 orientation: portrait”
“pattern: grid spacing: 0.25in paper: letter”
“pattern: grid spacing: 0.2in major: 5 paper: letter”
“pattern: dots spacing: 5mm paper: a4”
“pattern: lined spacing: 9/32in paper: letter”
“pattern: lined spacing: 11/32in margin: 15 paper: letter”
“pattern: isometric spacing: 10mm shade: light paper: a4 orientation: landscape”
“pattern: grid spacing: 1cm major: 0 paper: a4”
“pattern: hexagon spacing: 5mm margin: 2 colour: blue”
“pattern: dots spacing: 1mm”
Graph Paper Settings
Each setting goes on its own line as a name, a colon and a value, and the menus write the same lines. These are the settings this generator reads, the values each accepts, and what it uses when a line is missing.
pattern
grid, dots, lined or isometric. The default is grid.
“Which pattern suits a bullet journal?”
spacing
Distance between lines or dots: 5mm, 0.5cm, 0.25in or 1/4in, from 2 to 50 mm.
“How do you write a quarter inch?”
major
A heavier line every N squares on a grid, or 0 for none.
“What gives centimetre lines on a 5 mm grid?”
shade
light, medium or dark lines.
“Which shade disappears under ink best?”
margin
Blank border in millimetres, from 0 to 40. The default is 10.
“Why keep at least 5 mm?”
paper
letter or a4.
“Which paper is 8.5 × 11 inches?”
orientation
portrait or landscape.
“Which suits a wide floor plan?”
pages
How many identical sheets, from 1 to 20.
“How do you print a pad of 10?”
Common Graph Paper Standards
Some spacings are so common that they have names. Matching one of them means your printed paper lines up with textbooks, notebooks and worksheets that use the same standard, which matters for schoolwork, crafts and technical drawing. Each is a preset in the Spacing menu.
Quad Ruled
A quarter-inch square grid, the usual US school graph paper.
Engineering Paper
Five squares an inch (0.2 in), often with a heavier line every inch.
Metric Graph Paper
A 5 mm grid, or 1 mm with heavier lines every 5 and 10 mm.
College Ruled
Lines 9/32 inch (about 7.1 mm) apart, the common US notebook spacing.
Wide Ruled
Lines 11/32 inch (about 8.7 mm) apart, used for younger writers.
Dot Grid
Dots 5 mm apart, popular for bullet journals and sketch notes.
Which Pattern to Choose
Each pattern supports a different kind of drawing or writing. The best one is the one that guides your hand where you need it and stays out of the way everywhere else, so it is worth matching the pattern to the task before you print a whole stack of sheets.
Square Grid
Graphs, floor plans, pixel art, knitting and cross-stitch charts.
Dot Grid
Lettering, diagrams and journals, where full lines would be too busy.
Ruled Lines
Handwriting practice and notes, at school or notebook spacing.
Isometric Grid
3D sketches of objects, rooms and game levels at 30° angles.
Major Lines
Counting squares quickly, as when plotting to scale.
Millimetres, Inches and Fractions
Graph paper standards come from two systems: metric paper counts millimetres, while US paper counts fractions of an inch. The generator accepts either and converts to millimetres internally, so you can type the spacing the way your textbook, pattern or teacher describes it and get exactly that on paper.
Millimetres
Type 5, 5mm or 0.5cm for a five-millimetre grid; plain numbers are millimetres.
Decimal Inches
Type 0.25in or 0.2in for quarter-inch and fifth-inch grids.
Fractions
Type 1/4in, 3/8in or 9/32in, just as ruled paper standards are written.
Conversions
One inch is exactly 25.4 mm, so a quarter inch is 6.35 mm.
Mixing Projects
Keep one unit for a whole project so printed sheets line up with each other.
Printing Graph Paper Accurately
A grid is only useful if its squares are the size you asked for. The PDF is drawn to exact millimetres, so accuracy comes down to how the page is printed, and a few print dialog settings make the difference between true squares and slightly shrunken ones.
Actual Size
Choose actual size or 100% scale; fit to page shrinks every square.
Check With a Ruler
Measure ten squares after printing to confirm the spacing.
Paper Size Match
Set the printer to the same paper as the PDF, A4 or Letter.
Draft Mode
Draft or toner-saving modes can make light lines vanish; use normal quality.
Photocopies
Copiers often scale slightly, so print each sheet from the PDF instead.
When to Use a Graph Paper Generator
Whenever you need a few sheets of a specific grid now, rather than buying a pad, or need a spacing that shops don’t stock. It is also handy for teachers who want every student working on exactly the same grid, printed fresh for each lesson.
Maths Homework
Plot graphs and geometry on a clean grid.
Floor Plans
Draw rooms to scale with one square per foot or per 25 cm.
Craft Charts
Plan knitting, beading or cross-stitch patterns.
Game Design
Sketch maps and levels on squares or isometric grids.
Handwriting
Print ruled sheets at the spacing a class uses.
Graph Paper Pitfalls
Mistakes that make printed squares the wrong size or uneven, usually because of a setting in the print dialog rather than the PDF itself. Most are quick to fix once you know where to look, and a ruler will tell you straight away whether a sheet came out true.
Fit to Page
Scaling the PDF changes the spacing. Print at actual size.
Wrong Paper
A4 pages printed on Letter, or the reverse, get cropped or shrunk.
Tiny Margins
Most printers leave about 5 mm blank, so lines at the edge disappear.
Dark Lines
Dark grids compete with your drawing. Light is easiest to draw over.
Very Fine Spacing
Lines 2 mm apart need a sharp printer to stay distinct.
Mixing Units
Inches and millimetres don’t line up; pick one for a whole project.
