Printable Coordinate Plane
A free, numbered coordinate plane you can print — all four quadrants or
just quadrant 1, on Letter or A4. Plot points by hand, or do what no
other printable can: type an equation like x^2 - 3 and graph it right on the grid. Free, no signup.
Scroll / pinch to zoom in, drag to pan — to inspect peaks, roots and crossings. Printing always uses your settings.
A printable coordinate plane — numbered and to scale
Need a blank coordinate plane to plot points by hand? Set the axes to Centred for all four quadrants, or to the Corner for a quadrant-1 grid, keep axis numbers on, and print. It's a numbered coordinate grid and graph paper in one: every square is true-size vector (5 mm, 1 cm or 2 cm), so a 10×10 or 20×20 plane prints exactly to scale on US Letter or A4 — sharper than a scanned PDF, and you choose the quadrants, grid size and numbering. Great for math worksheets, plotting ordered pairs, and coordinate-graphing practice.
A graphing calculator that prints real graph paper
Most graphing tools live on a screen, and most printable graph paper is blank. This is the in-between nobody makes: type a function and it is drawn onto a proper, numbered, true-to-size grid you can print and hand out, stick in a notebook, or annotate by hand. Plot a parabola for a worksheet, sketch a sine wave for a lesson, or print a line and its reflection side by side — all as crisp vector PDF on Letter or A4.
How to type a function
Write the right-hand side of y = (the
y = itself is optional). Multiplication can
be implicit — 2x and 3(x+1) both work.
| You want | Type | Notes |
|---|---|---|
| Parabola | x^2 - 3 | Powers use ^ |
| Straight line | 2x + 1 | 2x means 2·x |
| Sine wave | sin(x) | Trig is in radians |
| Reciprocal | 1/x | Asymptotes are handled |
| Cubic | x^3 - 3x | Combine terms freely |
| Square root | sqrt(x) | Also: cbrt, abs |
| Exponential | 2^x | Or exp(x) |
| Logarithm | ln(x) | log = base 10 |
| Absolute value | log(|1 - x|) | Bars |…| = abs( ) |
Supported functions: sin cos tan asin acos atan sinh cosh tanh exp ln log log2 sqrt cbrt
abs sign floor ceil round min max pow, plus the constants pi and e.
What you can use it for
Making maths worksheets and answer keys, studying transformations of functions, plotting a quick reference curve, comparing two functions in different colours, or just getting a clean, labelled coordinate plane to plot points by hand. Need an empty grid instead? Use the plain graph paper generator, or the isometric paper for 3D sketches.

Frequently asked questions
- How do I print a four-quadrant coordinate plane?
- Set Axes to “Centred”, leave the function boxes empty, keep Show axis numbers on, then Print / Save as PDF. You get a clean, numbered four-quadrant coordinate plane. For a quadrant-1 grid (positive numbers only), set Axes to “Corner”. The “Blank plane” preset does this in one click.
- What size coordinate plane can I make — 10×10 or 20×20?
- Yes. The grid fills the page, so the number of units depends on the grid size and paper you pick: 1 cm squares give roughly a 20×20 plane on Letter, while 2 cm squares give about a 10×10. Every square is true-size vector, so it prints exactly to scale on US Letter or A4.
- Can I change the scale — what one square is worth?
- Yes. Set the X and Y scale independently to any value from 0.25 to 100 units per square. Use a small Y scale (e.g. 1 square = 0.25) so a low-amplitude curve like sin(x) fills the grid, or a large one for steep curves like x³. Turn on “Show the scale key” to print a small note on the sheet saying what one square equals on each axis. The squares stay physically the same size, so it still prints true-to-scale.
- What functions can I graph?
- Any single-variable function y = f(x): polynomials (x^2 - 3), fractions (1/x), roots (sqrt(x), cbrt(x)), trigonometry (sin, cos, tan and their inverses, in radians), exponentials (2^x, exp(x)) and logs (ln for natural log, log for base-10, log2, or log(base, value) for any base). You can also use pi and e, and absolute value either as abs(x) or with bars, e.g. |1 - x| or log(|1 - x|).
- How do I type powers, fractions and multiplication?
- Use ^ for powers (x^2), / for division (1/x or (x+1)/2), and you can write multiplication implicitly — 2x, 3(x+1) and 2sin(x) all work, as does 2*x if you prefer. A leading 'y =' or 'f(x) =' is optional.
- Can I plot more than one function at once?
- Yes. Enter up to three functions and each is drawn in its own colour, with a small equation key on the sheet — handy for comparing a function and its transformation, or a line and a curve.
- Is the printed graph paper actually to scale?
- Yes. The grid is drawn as true-size vector squares (you choose 5 mm, 1 cm or 2 cm cells), so when you print at 100% with margins set to None, every square measures exactly that on the page — on both US Letter and A4.
- Does it handle asymptotes like tan(x) or 1/x?
- Yes. Where a function shoots off to infinity (the asymptotes of tan(x), 1/x, ln(x) near 0), the curve is broken cleanly instead of drawing a false vertical line through the gap.
- Is it free, and does it work on Letter and A4?
- Completely free, no signup and no watermark. Choose US Letter (8.5 × 11 in) or A4, portrait or landscape, centre the axes for all four quadrants or drop them to the corner for quadrant-one work.
