About Random Shape Generator
Random Shape Generator produces geometric shapes on demand — pick from 14 two-dimensional forms (circle, triangle, square, rectangle, pentagon, hexagon, heptagon, octagon, star, diamond, ellipse, parallelogram, trapezoid, and cross) or 8 three-dimensional solids (cube, sphere, cylinder, cone, pyramid, torus, dodecahedron, and prism). Each generation assigns a random size between 40 and 120 units and a random rotation between 0 and 359 degrees, so no two outputs look the same. You can request anywhere from 1 to 20 shapes in a single click.
The tool is built around five color schemes: Random draws from a curated palette of 20 named hues such as Sapphire, Coral, and Jade; Monochrome picks a base hue and randomizes lightness and saturation within it; Pastel samples soft tints; Vibrant uses fully saturated electric tones; and Grayscale selects from ten neutral shades from Light Gray to Iron. Each shape card shows its name, dimension badge (2D or 3D), side count, vertex count, assigned color name and hex swatch, exact size value, and rotation in degrees — giving you concrete geometry metadata alongside the visual. When you find a shape you want, clicking Copy SVG puts ready-to-use SVG markup on your clipboard instantly.
Everything runs entirely in your browser — no files are uploaded, no shapes are stored on a server, and nothing requires a login. The SVG output is self-contained and paste-ready for any vector editor, CSS file, or HTML page. There are no usage limits and no cost.
Key Features
22 distinct shape types
14 flat 2D polygons and 8 isometric 3D solids, from a simple circle to a dodecahedron, giving you a wide variety to explore in one place.
Five color schemes with named colors
Random, Monochrome, Pastel, Vibrant, and Grayscale palettes each produce named colors with hex values, so you always know exactly what color was chosen.
Per-shape geometry metadata
Each result card shows the shape name, dimension (2D or 3D), number of sides or faces, vertex count, color, size, and rotation — useful for learning or documentation.
One-click SVG copy
Every generated shape has a Copy SVG button that places clean, self-contained SVG markup on your clipboard, ready to paste into code or a design tool.
Adjustable count up to 20
Generate between 1 and 20 shapes at once. Use a small count for targeted exploration or the maximum to survey a broad mix of forms and colors.
Fully client-side, no sign-up
All rendering happens locally in your browser using React and SVG. No data leaves your device, and there are no accounts, limits, or fees.
How to Use

Use Results
Review the shape name, geometry properties, and color, then click Copy SVG to grab the code.
Example
Generating one 2D shape with the Vibrant color scheme might produce a Hexagon at size 87, rotated 42 degrees, filled with Electric Blue (#0000ff). The copied SVG output is a standalone file you can paste directly into HTML or a vector editor.

- arrow_circle_right
Placeholder graphics for UI mockups
Drop a generated SVG hexagon or circle into a wireframe as a stand-in avatar, icon, or decorative element while waiting for final assets — unlike a random color or emoji generator, you get scalable vector geometry.
- arrow_circle_right
Geometry homework and classroom illustration
Students and teachers can generate any polygon or solid on demand, read its exact side and vertex count from the card, and copy the SVG to paste into a presentation or worksheet.
- arrow_circle_right
Pattern and background texture exploration
Generate 15–20 shapes in Pastel or Monochrome mode to audition a color-and-form palette for a repeating background pattern before committing to a full illustration tool.

SVG coding reference and learning
The copied SVG code shows real polygon point coordinates, transform attributes, and gradient definitions for 3D shapes — useful for developers learning how SVG geometry works in practice.

Random art prompts and creative warm-ups
Artists and designers use unexpected shape-and-color combinations as a starting constraint. Generating a Vibrant Torus or a Pastel Dodecahedron gives you a concrete visual prompt rather than a blank canvas.
