When discussing high-rise signage, one of the most common questions is: "How big should the logo be?"
Many assume that a standard logo size can work on any building. In reality, building height, viewing distance, and surrounding environments all influence the required signage dimensions.
As a general principle, the higher the installation point, the larger the signage may need to be to maintain visibility and brand recognition.
Finding the right balance between visibility, building aesthetics, and authority requirements is often one of the first considerations in any high-rise signage project.
In our experience, proper sizing is not about making a logo as large as possible it's about making it visible from where it matters most.
| Building Height (m) | Typical Viewing Distance (m) | Recommended Signage Area (m²) | Letter Height (mm) |
| 5–10 | 20–30 | 1–2 | 100–150 |
| 10–20 | 30–50 | 2–4 | 150–250 |
| 20–40 | 50–80 | 4–8 | 250–400 |
| 40–60 | 80–120 | 8–15 | 400–600 |
| >60 | >120 | 15–25 | 600–1000 |

Our role is to find the size that works best for the building not simply the largest size possible.
