Use this checklist to make sure your custom metal sign design is practical for laser cutting before checkout.
Laser cutting can follow very fine paths, but a good sign still needs readable lettering, enough metal around details, clean stencil bridges, sensible mounting, and visible but not overdone preview lines.

Minimum detail is about both cutting and readability. A laser can cut with high accuracy, but small islands, hairline gaps, and intricate curls may not be useful on a sign mounted outside.
If a detail matters, make it large enough to read at the intended viewing distance. If it is only decorative, remove it before it creates fragile geometry.
