How Do You Define LED Display Specs for a Small Commercial Project?

I’m planning a small commercial indoor LED display project and currently in the solution planning stage. The project has the following conditions:

  • Indoor commercial display (not large-scale advertising)

  • Installation in a lobby or in-store display area

  • Viewing distance around 2–6 meters

  • Content mainly includes brand videos and text information

  • Limited space, minimal structural work preferred

  • Hope to allow future resizing or upgrades

I’d love to hear from people who have real project planning or installation experience:

  1. At a 2–6 m viewing distance, how noticeable is the real-world difference between P1.8, P2.0, and P2.5?

  2. Do you usually lock in the final screen size from the start, or choose a modular setup for future expansion?

  3. For indoor spaces with ambient daylight, what brightness range has worked well in practice?

  4. During planning, do you typically select the screen first or plan the control system together with it?

  5. What requirements are most often overlooked early on (maintenance space, heat dissipation, cabling, upgrade costs)?

Any real-world experience, planning logic, photos, or model references would be greatly appreciated.
Looking for practical insights, not just spec sheets. Thanks!

We’ve worked on several small indoor commercial LED display projects in lobbies and retail spaces, with viewing distances typically around 2–6 meters. Here are some practical takeaways.

Pixel pitch:
At this distance, the difference between P1.8 and P2.0 is subtle, and P2.5 looks perfectly fine beyond 3 meters. For brand videos and text-based content, P2.5 often offers the best balance.

Screen size:
We usually prefer modular designs. Even when the size is confirmed early, future adjustments are much easier.

Brightness:
For indoor spaces with ambient daylight, around 800–1200 nits has worked well in practice.

Control system:
We typically consider the screen and control system together to avoid resolution or expansion limitations later.

Often overlooked:
Maintenance access, heat dissipation, and future upgrade paths are worth planning ahead.

Overall, matching the display to the viewing distance and real usage matters more than chasing extreme specs.
