1 cm Graph Paper

Why 1 cm spacing?

Centimeter grids are the metric standard used across most of the world outside the US, and they map cleanly onto A4 paper: a full A4 sheet with a reasonable margin fits roughly 18 columns and 26 rows of 1 cm squares. This size is common in primary and secondary school math, for plotting simple graphs, for scale drawings (1 square = 1 unit, or 1 square = 10 units for larger scale work), and for basic technical sketches where millimeter precision isn't required.

Need finer or coarser spacing?

If 1 cm is too coarse for detailed diagrams, switch the spacing to 5 mm or 2 mm using the presets above — both are common in engineering and drafting. For looser grids suited to handwriting practice, try switching units to inches and picking the 1/4 inch preset instead. The unit toggle converts your current spacing and margin automatically, so you won't lose your place when switching between metric and imperial.

Printing tips

Always print at 100% scale / Actual Size, not "Fit to page," or the 1 cm squares will come out slightly larger or smaller than intended. A quick way to confirm accuracy: measure five squares in a row with a ruler — they should span exactly 5 cm.

Scale drawings at 1:100 and other common ratios

A 1 cm grid is the natural base for scale drawing because the math stays in round numbers: at 1:100, each 1 cm square represents 1 metre in real life, the standard scale for floor plans, garden layouts, and basic architecture homework. At 1:50, each square represents 0.5 m — useful when you need more visible detail on a smaller space, like a single room instead of a whole floor. At 1:200, each square represents 2 m, better suited to site plans or landscaping layouts that cover more ground than a single building.

To draw a scale floor plan, measure the real room in metres, divide by the scale factor, and mark that many squares — a 4 m × 3 m bedroom at 1:100 becomes a 4-square × 3-square rectangle. Because the grid is already metric, you skip the conversion step that an inch-based grid would force on you when your source measurements are in metres.

The same approach works for garden and landscaping layouts, just at a coarser scale — 1:200 or 1:500 for a full yard, switching back to 1:50 for a detail sketch of a single flower bed or patio. Sketch the property boundary first using a printed compass direction as a reference, then place fixed features (the house, existing trees, a fence line) before filling in planned beds or paths, so everything stays proportional to the same scale instead of drifting as you add detail.

Metric science graphs students actually plot by hand

Centimetre-squared paper is the default for lab notebooks in schools that teach in SI units — plotting a plant's growth in centimetres per day, a pendulum's period in seconds against string length in centimetres, or temperature in Celsius against time in minutes all map directly onto the grid without a conversion step. Because 1 cm squares are large enough to hold a data point and a small label without crowding, they work well both for the axes themselves and for plotting individual measurements — mark the x-axis in whole squares per unit of time, and choose how many units each y-axis square represents so the full data set fits on one page.

For graphs with a wide value range — comparing a pendulum's period across many string lengths, for instance — switch to 5 mm spacing to fit twice as many data points per axis without the plot becoming unreadably small.

Lab notebooks that see repeated handling — passed between partners during an experiment, annotated in pencil then re-inked, or stored in a folder for a full term — hold up better on 24 lb (90 gsm) paper than standard 20 lb copy paper, which tends to show through when a multi-page investigation is printed double-sided.

How 1 cm squares map to school curricula

"Centimetre squared paper" is the standard term used in UK, European, and international curricula (including IB and Cambridge syllabuses) for exercise-book grids used from roughly age 10 through secondary school science and maths. It sits between the finer 5 mm grid used for detailed graph work and the plain 7–8 mm ruled paper used for regular handwriting. If a homework sheet or exam board specifies "squared paper" without more detail, 1 cm is the safe default; check the syllabus or past papers if a specific spacing — usually 2 mm or 5 mm for higher-level maths and physics — is called for instead. GCSE and A-level physics practicals in particular often print "graph paper" on the exam itself but leave the spacing unspecified for coursework and homework, where 1 cm remains the conventional choice. The full Graph Paper Generator covers both of those finer spacings if you need them.
