Graph paper on screen
This is a sheet of graph paper you can draw on in your browser. The page is a true Letter or A4 page with 5 mm, quarter-inch, 1 cm or half-inch squares, the same sizes as our printable graph paper. Anything you draw is stored in real millimetres, so the PDF you download prints exactly as you see it, square for square.
Use it to sketch a floor plan or a garden layout at a scale of one square to a foot or a metre, plan a pixel picture or a knitting chart, draw a geometry diagram for homework, or plot the points of a data set. Teachers can prepare a worked example, project it on a board and print copies for the class from the same drawing.
Tools
- Line draws a straight segment: press, drag and let go. With snap on, both ends land on grid corners.
- Point plots a dot at a grid corner and labels it A, B, C and so on, the usual way to name points in coordinate geometry.
- Pen draws freehand, for curves, shading and sketches.
- Text places a short label wherever you click.
- Eraser removes the nearest line, point or label under the pointer.
Four ink colours keep different parts of a diagram apart, such as a shape and its reflection, or two data sets.
Axes and functions
Choose centred axes for all four quadrants, with the origin in the middle of the page, or first quadrant for positive values only, with the origin near the bottom left, which suits most data and distance-time graphs. The axes are numbered in squares, and the readout under the page shows the coordinates of the grid corner under the pointer.
With the axes on, type an equation into a y = box to draw its graph: straight lines such as 2x + 1 or −x/2 + 3, parabolas such as x^2 − 4, and curves such as sqrt(x), 1/x or 2sin(x). The expression is read by the page itself rather than run as code, and if it cannot be read the box tells you why. Each function takes the next ink colour, so up to four can be compared on one page.
Printing and saving
Download a PDF and print it at 100% or Actual size for a true-size sheet. PNG and SVG downloads suit slides, worksheets and documents; SVG stays sharp at any size. Your drawing is saved in this browser automatically, so you can close the page and carry on later on the same device.
For blank sheets to fill in by hand, the graph paper generator has more sizes and options, including bold lines every inch or centimetre, and coordinate plane paper prints several small numbered grids per page.
Frequently asked questions
Can I plot a graph of an equation?
Yes. Turn on the axes and type up to four functions, such as 2x + 1, x^2 − 3 or sin(x), in the y = boxes. One square is one unit, and curves that leave the page, like tan(x), are split where they jump.
Is my drawing saved?
It is saved in this browser on this device as you draw, so it is still there when you come back. Nothing is uploaded. Clearing your browser data removes it, so download a PDF of anything you want to keep.
Will it print at the right size?
Yes. The PDF is a true-size Letter or A4 page: quarter-inch squares print at exactly a quarter of an inch when you print at 100% or Actual size. If you have calibrated your printer on this site, the PDF includes the correction.
Does it work on a tablet or phone?
Yes. Draw with a finger or a stylus; the page does not scroll while you draw on it. A larger screen is more comfortable for detailed work.
What does snap to grid do?
With snap on, points, lines and text jump to the nearest grid corner, which keeps plotted points exact. Turn it off for freehand placement. The pen is always freehand.
Can I undo a mistake?
Yes. Use Undo and Redo, or Ctrl+Z and Ctrl+Y (Cmd on a Mac). The eraser removes the nearest line, point or label you drag across.
