Press New page for a mandala, a stained glass window, or a sheet of quilt blocks, drawn fresh in your browser. Bold lines for preschool crayons, thin lines for gel pens, and a page code to print the same sheet again next week.
Pick a color, tap a shape
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. |
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.
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.
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.
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.
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.
G3-60418.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.
| Crayons, colored pencils | Standard 20 lb (75 gsm) copy paper |
| Washable markers | 24 to 32 lb (90 to 120 gsm), less show-through |
| Alcohol markers | 65 lb (176 gsm) cardstock with a scrap sheet underneath. Thinner paper bleeds through to the table. |
| Watercolor or paint sticks | Heavy cardstock from a laser printer. Inkjet lines smear once they get wet. |
Pick a crayon from the column beside the sheet, then tap a shape. Focus mode fills the screen with the sheet and the colors, so there is no scrolling between them. The square after the gray swatch opens your device's full color picker.
Eraser turns one shape back to white. Clear colors wipes every fill and keeps the drawing.
you change line weight, paper size, or the name. Fills follow their shapes.
you press New page or change style, detail, or symmetry. Print or save a PNG first.
Yes. There is no sign-up and no watermark. Each page is drawn from a random number in your browser, so print as many copies as the class needs, or photocopy one sheet.
Note the code above the sheet, for example M2-8-41275, or press Copy link. Anyone loading the code gets the identical pattern. For a different page per student, press New page between prints.
Stained glass, Big shapes, and Bold lines. The result is 16 large panes with heavy outlines. Mandala at Big shapes is the next step up, at around 70 shapes.
Yes. Print, the PNG, and the SVG all include your fills. Press Clear colors first for a blank sheet.
Either your printer needs a wider margin than the 0.3 inch the sheet leaves, or the paper size in the print dialog differs from the Paper setting. Match the two sizes, then pick Fit to page in the dialog.
No. Drawing, coloring, and both downloads happen in your browser. A copied link holds only the page code.
