# 2mm Graph Paper > 2 mm squares with a bold line every centimeter: finer than 5 mm paper, easier on the eye than millimeter paper. Free printable 2mm graph paper from Printable Graph Paper. Page: https://printablegraphpaper.org/graph-paper/graph-paper-2mm 2 mm graph paper sits between the two classic metric rulings. It has more resolution than 5 mm paper, but without the density of millimeter paper: five small squares make each bold centimeter, so plotting and reading values stays quick. ## At a glance - Category: [Grid Paper](https://printablegraphpaper.org/category/grid) - Paper sizes: Letter (8.5" × 11"), A4 (210 × 297 mm), 11" × 17", Legal (8.5" × 14"), A3 (297 × 420 mm), A2 (420 × 594 mm), Poster (18" × 24"), Movie Poster (27" × 40"), Letter Landscape (11" × 8.5"), A4 Landscape (297 × 210 mm), Tabloid Landscape (17" × 11") - Line colors: Faint, Light, Gray, Dark, Black, Blue, Green (default: Gray) - Format: vector PDF download at exact physical scale, or direct browser print - Price: free, no signup, no watermark; printed sheets may be used for personal, classroom and commercial work ## Good for - School science and maths graphs with a line of best fit - Plotting experimental data that needs more resolution than 5 mm - Detailed technical sketches and diagrams - Pixel art, mosaics and small-scale pattern design ## About 2mm graph paper 2 mm paper is a common choice for graph work in schools and labs because it balances precision against readability. Each bold centimeter is split into five cells, so a value can be plotted to a fifth of a unit, which is usually more precision than school-level data supports. Compared with [millimeter paper](https://printablegraphpaper.org/graph-paper/graph-paper-1mm), the page looks far calmer, which matters when the plotted points and the line through them should be the most visible things on the page. Compared with [5 mm paper](https://printablegraphpaper.org/graph-paper/graph-paper-5mm), it gives two and a half times the resolution along each axis, enough to read a gradient or an intercept with confidence. ## What's on the page A 2 mm grid in hairline (0.1 mm) lines with bold 0.25 mm lines every 1 cm (every fifth line). The grid is trimmed to whole centimeters and centred: 95 × 125 cells (19 × 25 cm) on US Letter and 90 × 135 cells (18 × 27 cm) on A4. Landscape sizes are available for graphs with long horizontal axes. ## How to use it well - **Make each bold line a round number.** Set the scale so one centimeter is 1, 2, 5 or 10 units. Each small cell is then a fifth of that, which keeps plotting to simple counting rather than arithmetic. - **Use as much of the page as you can.** Choose a scale that makes your data fill at least half the grid in each direction. A graph squeezed into one corner wastes the resolution and makes gradients hard to read. - **Plot with small crosses.** Mark points with a small × or + about one cell across. Dots get lost in the grid and large blobs hide the true position. - **Draw best-fit lines with a clear ruler.** A transparent ruler lets you see points on both sides of the line while you position it, so roughly equal numbers of points fall above and below. ## Common mistakes to avoid - Scaling with 'Fit to page'. A small shrink makes each centimeter slightly short, which skews any value you read off the graph. Print at 100 percent. - Choosing awkward scales. If one centimeter is 3 or 7 units, each 2 mm cell becomes an awkward fraction and plotting errors creep in. Stick to scales based on 1, 2 and 5. - Starting both axes at zero when the data doesn't need it. If all your values sit between 40 and 60, a zero-based axis wastes most of the page. Break the axis or start it nearer your data. ## FAQ ### How is 2 mm paper different from millimeter paper? [Millimeter paper](https://printablegraphpaper.org/graph-paper/graph-paper-1mm) has 1 mm squares with lines at 5 mm and 1 cm. 2 mm paper has squares twice as wide and only two line weights, so it is easier to read at a glance while still giving five divisions per centimeter. ### How many squares are on an A4 page? 90 × 135 squares, which is 18 × 27 cm of grid. On US Letter it's 95 × 125 squares (19 × 25 cm). ### Is 2 mm the same as 1/12 inch? No. 1/12 inch is about 2.12 mm, so the two drift apart by 1 mm roughly every eight or nine cells. If you need inch-based rulings, use [1/8 inch](https://printablegraphpaper.org/graph-paper/graph-paper-eighth-inch) or [5 squares per inch](https://printablegraphpaper.org/graph-paper/graph-paper-5-squares-per-inch) paper. ### Which line colour should I choose? Gray works for most graphs. Choose Light if you want your plotted points and lines to stand out more, or Dark if the sheet will be photocopied. ### Can I use it for pixel art? Yes. The small square cells and the bold centimeter blocks make it easy to count out sprites and patterns. For larger, easier-to-colour pixels, [5 mm paper](https://printablegraphpaper.org/graph-paper/graph-paper-5mm) is a better fit. ## How to print at the correct size Set the browser print scale to 100% (never "Fit to page") and margins to None or Minimum, or use the Download button for a PDF dimensioned in millimetres. To check, measure 5 cells with a ruler: a 5 mm grid should read 25 mm.
