Every grid maker and calculator in one place.

A numbered square grid over your reference, 4 to 40 cells across, for copying a drawing square by square.

Turn a photograph into a counted-stitch chart, with the cell count matched to your fabric.

Ball-and-plane head construction placed over a portrait reference at any angle of tilt or turn.

One, two, three and five-point armatures for scenes that need depth and a believable horizon.

30/60° isometric plus dimetric and trimetric variants, for technical drawing and game art.

The fastest composition check there is, with phi and diagonal variants alongside it for comparison.

Phi grid, golden rectangle, and the golden spiral, rotatable to any corner of the frame.

Thirds, phi and diagonal overlays for judging a frame before you commit to a crop.

Flower of Life, Metatron’s Cube, Sri Yantra, Vesica Piscis and the rest of the constructions.

The nine-triangle yantra computed rather than traced, so the intersections hold at stencil and mural scale.

Nineteen equal circles on a hexagonal lattice, each centred on another's circumference, inside the two rings that close the figure

Thirteen circles from the Fruit of Life, joined by all seventy-eight lines their centres allow

Seven equal circles: one at the centre, six around it with their centres on its circumference

Ten sefirot arranged across three vertical pillars, joined by twenty-two paths

Two equal circles, each passing through the other's centre, and the pointed lens between them

Column, modular, baseline and template grids drawn over your own screenshot or artwork rather than beside it, with margins, gutters and module counts adjustable…

Choose how many columns and rows, see every tile at the size it will be saved, and take them one at a time or all at once as a ZIP

Enter the size you are copying from and the size you are copying onto

Enter a size and get its true reduced ratio

Three columns, as many rows as you want, cut in your browser and numbered in the order you actually have to post them

Fourteen lines built from nothing but the four corners and the four edge midpoints, crossing at thirty-seven points that stay in the same relative places…

A stack of horizontal rungs laid over the page you actually made, so you can see which lines of type are sitting on the rhythm and which are floating half a line…

Brow, eye, nose, mouth and ear guides laid over your own reference, with a different set of fractions for an adult, a teen, a child and a baby

Seven quarter-arcs across a golden-rectangle subdivision, with the eye placeable in any of the four corners

One diagonal, two perpendiculars dropped onto it from the opposite corners, and the two points where they land

A 1 : 1.618 rectangle is only a shape. Add both diagonals, the four reciprocals dropped onto them at right angles, and the four eyes where those land, and it…

Pointy-top or flat-top, at whatever density the terrain wants, tiled cleanly past every edge

Choose the sheet, choose the spacing, export at up to 600 DPI

A one point perspective grid built to your eye level and your viewpoint rather than to a template's

Two points on the horizon and one above or below the frame

Five points on a circle, joined every other one

A six-pointed star is the simplest figure in this catalogue and the easiest to draw slightly wrong, because both triangles have to be equilateral and share a…

Two interlocking triangles, plus the hexagon that passes through all six of their points

The S-curve is not freehand. It is two semicircles of exactly half the outer radius, and the eyes sit at their centres — which is the whole construction, and the…

Tetrahedron, cube, octahedron, icosahedron, dodecahedron

Concentric ellipses from the hole out to the rim, crossed by spokes

The star that carries half of Islamic ornament is two squares on one circle, turned 45° from each other

The richest unit in Islamic geometric ornament, and one of the simplest to build: two hexagons on one circle, turned thirty degrees from each other, with no…

One circle, a ring of six, a second ring of six

The whole figure turns on one number: the surrounding centres sit at exactly two radii, so every circle meets its neighbours at a single point and never crosses…

The trinity knot is not three loops drawn by hand

The figure behind both the Borromean rings and every three-set Venn diagram is one arrangement: three equal circles, centres half a radius out, 120° apart

One to twenty rings at exactly equal radial intervals, with the three pillars and the ten sephirot names available

1 : 1.41421 is the proportion of every A-series sheet, and it is the one rectangle whose dynamic-symmetry eyes land exactly on the rule-of-thirds intersections.

1 : 1.73205 is the number the hexagon and the vesica piscis both produce, and it is the rectangle whose armature lands on the quarters rather than the thirds.

One to two is the only rational member of the root family

1 : 2.23607 divides into a central square flanked by two strips of exactly 0.618

3:2 is 35mm film and most camera sensors, and it is the one common proportion whose dynamic-symmetry eyes sit near the thirds without landing on them

Thirds gives you four intersections and one answer

A grid where the two levels are drawn at different weights, so you read the halving first and the quartering second

One from each corner, each running the length of the frame's short side

Every off-centre system in this catalogue deliberately avoids the middle

The perspective system for a 180° field of view: four vanishing points spaced around the rim of a disk, a fifth in the middle, and two families of arcs that…

The projection that sits between isometric and full perspective: two receding directions at angles you choose, no vanishing points, and nothing getting smaller…

The most flexible axonometric projection, and the one nobody draws by hand: every axis at its own angle, every axis at its own foreshortening, no vanishing…

The grid for pavement art, floor murals and every image built to snap into shape from a single viewing position

The equilateral tessellation: three line directions instead of two, six triangles at every vertex, and a row height that is never a round number.

The scaffold under every mandala, rosette window and radial ornament: circles you can count outward and divisions you can count round, neither of them guessed.

Polar graph paper with a spiral on top — Archimedean when you want even turns, golden when you want growth. Both drawn against a ring-and-spoke reference you can…

Two crossing families anywhere between 20° and 70°

All the registration of a square grid with a fraction of the ink: a small cross at every crossing point, sized from a discreet tick to something close to a full…

Four guides in a complete golden-ratio series, tied to the body rather than to the page

A layout grid that draws both edges of every column, so the gutter is a band you can see rather than a number you have to trust.

A column grid organises the horizontal. A modular grid organises both, and the number of usable groupings it produces is much larger than the module count suggests.

The simplest grid there is and the hardest to get right: a single text area, three margins, and the question every book designer has argued about for six hundred…

Not every layout wants a regular field. When the content has a hierarchy that a module count cannot express, the grid should have one too.

The spacing system every design system converges on, drawn at two weights so the major rhythm and the half-step sub-rhythm are visibly different things.

The grid a building is set out from: lines that locate structure, nodes that are the structure, and a reference system so that everybody on site means the same…

A grid with a rhythm instead of a spacing: wide and narrow bands in both directions, every third line heavier, and the two emphasis sets offset from each other…

The grid method's most useful and most dangerous variant: cells that need not be square, and the one arithmetic check that stops them stretching your copy.

Every other grid here asks how many cells you want

Fold the short side of a rectangle onto itself and you get a square

Drop a perpendicular from each corner onto the opposite diagonal

The rising diagonal, and the reason a picture built along it reads as expansive when the identical line mirrored reads as closing down.

Geometrically it is the baroque diagonal reflected

Enlarging a drawing is not a scale factor problem

A grid for a wall is a different problem from a grid for a sheet

Every other grid here divides a frame into parts

Change the head count and the pelvis mark does not move

A transfer grid gives you cells. Adding one diagonal to each gives you triangles, and a triangle is a shape the eye judges far more accurately than a square.

Both diagonals in every cell. The obvious result is four triangles instead of one square; the useful one is that the crossing marks each cell's exact centre for…

The grid that makes a set of icons look like a set

The grid a mark gets refined against rather than designed on: a divided square, its diagonals and medians, and three circles whose radii sit in the oldest ratio…

Five aspect ratios and three safe areas at the insets broadcast has used for seventy years

A regular page grid is the thing you break, and you cannot break something you have not drawn

A poster has rows for its blocks and baselines for its type, and they are different grids

Two device proportions with the system chrome marked

Choose A4 or Letter, set the square in millimetres or inches, and print

Drop in the photographs, choose how many columns and what shape the cells are, and take one composed image out

Point the phone at your paper, float the reference over the live view, and draw what you see through the screen

Dot, isometric, hexagonal, ruled or square, at any spacing in millimetres, centimetres or inches

Printable sheets with columns lettered and rows numbered, at the cell size the lesson needs

Choose how many colours and how small an area is still worth painting

Drop in a photograph and pull the detail down until only the shapes you want to colour are left

The hard part of drawing a mandala by hand is making the repeats identical

Drop in a photograph, pick the overlay, take the file

Cut a picture into three, six or nine tiles that reassemble into the whole image on your profile

A grid cell you cannot span with your arm is useless on a wall, because you cannot see the cell and the reference at the same time

Stretched canvases come in a handful of ratios, almost none of which match a camera

Twelve is not a design preference. It is the smallest useful number that divides by two, three, four and six, which is why one grid can carry halves, thirds,…
