Design Guide: 1536 × 864 Touch Screen
This guide applies the principles in docs/ (spacing, hierarchy, touch ergonomics, and dashboard standards) to a fixed 1536 × 864 px viewport with touch as the primary input.
1. Viewport context
| Property | Value | Notes |
|---|
| Resolution | 1536 × 864 | Same 16:9 aspect as 1920×1080; linear scale ≈ 80% of Full HD. |
| Input | Touch first | Treat pointer hover as optional; all primary actions must be finger-reachable. |
| Mental model | Panel / kiosk / HMI | Prefer predictable regions, large targets, and low mis-tap risk over dense “mouse” layouts. |
2. Layout grid and margins
Align with the 1320px / 12-column content logic from the design system, adapted to this width:
- Max content width: 1320px, horizontally centered when possible.
- Side margin ≈
(1536 − 1320) / 2 = 108px per side on a full-bleed artboard.
- 8px base grid: Use rhythm 8, 12, 16, 20, 24, 32, 48, 64, 80 for padding and gaps (per UI specification and white-space workshop).
- Section separation: Gap between unrelated blocks should be the gap inside a block (proximity rule). Prefer between major sections; use for strong “chapter” breaks.
