Flat Design / Vector Minimalism vs Isometric Illustration
フラットデザイン / ベクターミニマリズム / アイソメトリック・イラストレーション
Flat Design / Vector Minimalism comes from UI Expression and Isometric Illustration from Diagrammatic Expression. One is style and the other technique. They are reached for with some of the same intent, which is where they get confused.
Flat Design / Vector Minimalism
Reduces information to plain planes and color, portable across screens and media.
Isometric Illustration
Keeps depth while looking down from above, explaining relationships among many parts in a single image.
| Flat Design / Vector Minimalism | Isometric Illustration | |
|---|---|---|
| Era | 2010s– | technical drawing–digital |
| Family | UI Expression | Diagrammatic Expression |
| Kind | Style | Technique |
| Cues | Uniform planes / Simple shapes / Few shadows / Clear color | 30-degree axes / Uniform scale / Exploded views / Little worlds |
| Best used for | Light, understandable explanation · Large sets of consistent figures | Showing the whole of a system or space · Friendly diagrams of complex relations |
| Type | A rounded sans-serif | A concise sans with small labels |
| Composition | Simple silhouettes and clear hierarchy | Fix the three axes; enlarge only what matters |
| Material | Three to five colors; shadows only when they mean something | Value steps per plane, thin outlines, limited color |
| Caution | Figures easily become generic. Define your own ratios, lines and color rules. | Don't draw everything at equal density. Pull the eye to the relation you're explaining. |
