AI-assisted article

This article was prepared with AI assistance based on an analysis of the current Lumina Studio source code, existing Wiki content, and relevant workflows. It has been checked against the current version, but omissions or details that become outdated may remain as the software evolves. If you find an error or have a clearer explanation, example, or suggestion, please leave a comment on this page or propose an edit on GitHub.

Output Width and Height

Width and Height describe the printed XY size in millimetres. They are not the pixel dimensions of the uploaded image.

Aspect-ratio coupling

After upload, Lumina Studio records the source aspect ratio. Changing Width recalculates Height; changing Height recalculates Width. The linked result is rounded to millimetres and clamped to the active range.

Normal mode allows 10–400 mm. Large Format expands the upper limit to 9999 mm, but that does not mean one printer can produce the size in a single job. Check the build plate or use Large Format.

What dimensions affect

• final XY model size;
• the processing grid used to sample the image;
• the automatic Quantize Colors suggestion;
• placement of loops, magnet pockets, outlines, and other attached geometry.

High-Fidelity raster processing normally uses about 10 px/mm. Pixel Art uses nozzle width as its pixel scale. High-Fidelity SVG uses the SVG raster density in Settings. See Modeling Mode.

Changing either dimension invalidates generated output. Regenerate the preview instead of enlarging an old browser image.
