# My Graph Paper: paper sizes, rulings, sheet rules and chart values, one per line
# Source: our own drawings, explained at https://mygraphpaper.app/how-it-works/ (checked 2026-10-12). Paper sizes are the ISO 216 and US sizes; 1 inch = 25.4 mm exactly.
# Format: kind | name | fact | page
Sheet | A4 | 210 × 297 mm portrait (8.27 × 11.69 in) | https://mygraphpaper.app/
Sheet | US Letter | 215.9 × 279.4 mm portrait (8.50 × 11.00 in) | https://mygraphpaper.app/
Sheet | US Legal | 215.9 × 355.6 mm portrait (8.50 × 14.00 in) | https://mygraphpaper.app/
Sheet | A5 | 148 × 210 mm portrait (5.83 × 8.27 in) | https://mygraphpaper.app/
Sheet | A3 | 297 × 420 mm portrait (11.69 × 16.54 in) | https://mygraphpaper.app/

Rule | Inch to millimetre | 1 inch = 25.4 mm exactly, so quarter-inch squares are 6.35 mm and 5 squares per inch is 5.08 mm | https://mygraphpaper.app/
Rule | Squares on a page | squares across = floor((page width - 2 × margin) ÷ square size); the grid is centred, so 5 mm squares on A4 with a 10 mm margin give 38 × 55 squares | https://mygraphpaper.app/
Rule | Heavy lines | a heavier line every N squares is drawn at 2.2 × the light line weight; 1 cm paper usually has a heavy line every 5 or 10 squares | https://mygraphpaper.app/grid-paper/
Rule | Dot grid | dots sit at every grid intersection; 5 mm spacing on A4 with a 10 mm margin gives 39 × 56 dots | https://mygraphpaper.app/dot-grid-paper/
Ruling | Wide ruled | 8.7 mm between lines | https://mygraphpaper.app/lined-paper/
Ruling | College ruled | 7.1 mm between lines | https://mygraphpaper.app/lined-paper/
Ruling | Narrow ruled | 6.35 mm between lines | https://mygraphpaper.app/lined-paper/
Ruling | Seyès / French ruling | 8 mm between lines | https://mygraphpaper.app/lined-paper/
Rule | Isometric grid | vertical lines plus lines at +30° and -30°; the distance between parallel lines is the triangle height, and the triangle side is height ÷ cos 30° (8 mm height gives 9.24 mm sides) | https://mygraphpaper.app/isometric-graph-paper/
Rule | Polar grid | equally spaced rings and a radial line every chosen number of degrees: 15° gives 24 lines, 10° gives 36, 5° gives 72; every fifth ring is heavier | https://mygraphpaper.app/polar-graph-paper/
Rule | Hexagon size | a regular hexagon with side a is 2a across its points and a√3 (1.732a) across its flats; a 6 mm side gives 12 mm point to point | https://mygraphpaper.app/hexagonal-graph-paper/
Rule | Engineering paper | 5 squares per inch (5.08 mm) in a light green, 0.75 in margins each side, a ruled header 0.9 in deep split into three boxes | https://mygraphpaper.app/engineering-paper/
Rule | Handwriting lines | three lines per row: top, dashed middle and base; common US sizes are about 28 mm (1 1/8 in) rows for kindergarten, 16 mm (5/8 in) for first grade, 13 mm (1/2 in) for second and 9.5 mm (3/8 in) after, and schools differ | https://mygraphpaper.app/handwriting-paper/
Rule | Cornell notes | a header for topic and date, a cue column about a third of the width, a notes area, and a summary box at the foot (the classic is about 5 cm deep) | https://mygraphpaper.app/cornell-notes-template/
Rule | Staff paper | each staff is five lines; printed music spaces them about 1.75 mm apart, so a staff is 7 mm tall; 10 to 12 staves fit an A4 page | https://mygraphpaper.app/blank-sheet-music/

Rule | Multiplication chart | the cell in row r and column c holds r × c; the diagonal holds the square numbers 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 | https://mygraphpaper.app/multiplication-chart/
