# SpecSprout sample evidence — preliminary dimension notes

**Illustrative learning file only. These are preliminary notes, not a released drawing.**

- Target top-surface width: approximately **600 mm**.
- Target useful depth: approximately **220–260 mm**.
- Desired keyboard-clearance height: at least **55 mm** in the lowest useful configuration.
- Final overall height: **not fixed**.
- Final dimensional tolerances: **not specified**.
- Interface dimensions for removable/repositionable supports: **not specified**.
- Edge radii/chamfers: **not specified**.

These values should be treated as partial evidence until a controlled drawing or approved specification confirms them.
