Pick settings by who holds the crayon
Shape size matters more than style. A 4-year-old with a jumbo crayon needs regions wider than a thumb. An adult with a 0.4 mm fine-liner gets bored by those same regions in ten minutes. The shape counts below come from 200 generated pages per setting on US Letter.
| Who is coloring | Settings | What you get |
| Ages 3 to 5, jumbo crayons | Stained glass, Big shapes, Bold | 16 panes, each about the size of a child's palm. Bold lines hide the scribbles past the edge. |
| Ages 6 to 9, washable markers | Quilt blocks or Mandala, Big shapes, Medium | 24 to 36 quilt shapes, or 70 to 78 mandala shapes. One sitting, start to finish. |
| Ages 10 and up, colored pencils | Mandala, Medium, Medium | 196 to 500 shapes. A rainy afternoon, with rings wide enough to practice shading. |
| Adults with fine-liners or gel pens | Mandala, Fine detail, Thin | 470 to 1,170 shapes. The outer rings get narrow, so use a tip of 0.5 mm or finer. |
| A class set of 25 identical sheets | Any style, Bold | Print one sheet from a page code, then photocopy. Thin lines come out faint or broken on most copiers. |
| Door sign or party place card | Quilt blocks, Big shapes, Bold, plus a name | The name runs across the top in outline letters, and the blocks below stay big enough for younger guests. |
How each style is drawn
None of the pages come from a stock image. Each one is built from geometry the moment you press New page, which is why the same style never repeats unless you load its code.
Mandala
Rings grow outward from a small flower in the center. Each ring picks one shape, a petal, double petal, arch, spike, dot, or teardrop, and repeats the shape around the circle. Symmetry sets the base count, and wide rings double the count so shapes stay slim. Tall pages get quarter-circle fans in the corners.
Coloring tip: one color per ring gives a finished look with only four or five crayons.
- Big shapes
- 70 to 78 shapes
- Medium
- 196 to 500 shapes
- Fine detail
- 470 to 1,170 shapes
Stained glass
Points get scattered across the page, then every spot on the sheet joins the pane of its nearest point. Mathematicians call this a Voronoi diagram. Lines print 45% thicker than the other styles to read as lead. On Medium and Fine, about 3 panes in 10 hold a jewel: a circle or a smaller pane set inside.
Coloring tip: keep touching panes in different colors. Four colors always cover the whole sheet, a result known as the four color theorem.
- Big shapes
- 16 panes
- Medium
- 43 to 56 shapes
- Fine detail
- 92 to 116 shapes
Quilt blocks
A grid of square blocks, 3 by 4, 5 by 7, or 7 by 9, mirrored left to right and top to bottom the way pieced quilts are laid out. Blocks come from traditional patterns: half-square triangles, quarter-square triangles, bullseye, diamond in a square, quarter arcs, pinwheel, flying geese, and nine-patch. Medium and Fine add a sawtooth border.
Coloring tip: mirrored blocks look best in matching colors, so finish one corner and repeat those colors in the other three.
- Big shapes
- 24 to 36 shapes
- Medium
- 229 to 342 shapes
- Fine detail
- 419 to 593 shapes
Page codes bring back the same sheet
Every page gets a code, shown above the sheet. Type the code into Page code, press Load, and the identical pattern comes back on any phone, laptop, or school computer.

- Style letter: M for mandala, G for stained glass, Q for quilt blocks.
- Detail digit: 1 for Big shapes, 2 for Medium, 3 for Fine detail.
- Symmetry: mandala codes only. Stained glass and quilt codes have no symmetry part, as in
G3-60418.
- Seed: the random number behind the layout.
Line weight, paper size, and the name banner stay out of the code. Load M2-8-41275, switch to Bold and A4, and you get the same 316-shape mandala with heavier lines. A name shrinks the drawing to make room at the top, with the pattern unchanged.
Copy link puts the code in the address, for example toolexe.com/generator/random-coloring-page?code=Q1-27093. Send the link to a co-teacher or a grandparent and they print the same 28-shape quilt you printed. The Recent row under the sheet holds the last six codes from this visit and empties when you close the tab.
