A plain 1 mm grid is hard to read without guide lines. For lab graphs, millimeter graph paper with heavier 5 mm and 1 cm lines is easier to use.
What 1 mm graph paper is good for
- Lab graphs.
- Drafting and scale drawings.
- Measuring irregular areas.
How many 1 mm squares fit on a page
Whole squares only, grid centered on the page. With a 10 mm (about 0.4 inch) margin and with no margin:
| Paper | 10 mm margin | No margin |
|---|---|---|
| Letter (8.5 × 11 in) | 195 × 259 = 50,505 | 215 × 279 = 59,985 |
| Legal (8.5 × 14 in) | 195 × 335 = 65,325 | 215 × 355 = 76,325 |
| Tabloid (11 × 17 in) | 259 × 411 = 106,449 | 279 × 431 = 120,249 |
| A4 (210 × 297 mm) | 190 × 277 = 52,630 | 210 × 297 = 62,370 |
| A3 (297 × 420 mm) | 277 × 400 = 110,800 | 297 × 420 = 124,740 |
| A5 (148 × 210 mm) | 128 × 190 = 24,320 | 148 × 210 = 31,080 |
With small squares, a thin line in a light color keeps the page from looking gray.
