An isometric cube is a 2D representation of a 3D cube using isometric projection, where the three visible faces are drawn at 30-degree angles to the horizontal. Unlike perspective projection, isometric projection has no vanishing point — parallel lines remain parallel. This makes it ideal for technical drawings, pixel art, game assets, and architectural diagrams where measurements need to remain consistent across the scene.

For natural-looking lighting, follow the "top-bright, left-mid, right-dark" rule assuming a light source from the upper-left. The top face should be the lightest shade, the left face a medium shade (about 15-25% darker than top), and the right face the darkest (about 30-45% darker than top). Our built-in color presets automatically apply this lighting principle. You can also toggle the shadow feature to enhance depth perception.

Yes! Use the Width (W), Depth (D), and Height (H) sliders to independently control each dimension. This lets you create elongated boxes, flat platforms, tall pillars, or any rectangular prism in isometric view. Click the "Make Cube" button to quickly reset all three dimensions to the same value for a perfect cube.

The tool exports your isometric box as a PNG image with transparency (the background is transparent outside the box and shadow). PNG is widely supported in game engines like Unity, Godot, and Unreal Engine, as well as graphic design tools like Photoshop, Figma, and Aseprite. The exported image preserves the exact pixel dimensions you see on screen, making it ready for both high-resolution and pixel-art workflows.

The isometric grid overlay displays faint 30-degree guide lines across the canvas. This grid helps you visualize the isometric plane and understand how the box sits in 3D space. It's especially useful for aligning multiple boxes if you're planning a larger isometric composition. Toggle it on/off with the Grid button above the canvas.

Absolutely! This isometric cube generator is 100% free for both personal and commercial use. You can export unlimited boxes, use them in game assets, illustrations, presentations, websites, or any other project without attribution.
