LED Wall Size Calculator — Frequently asked

Long-form answers to the questions architects, AV consultants and owners ask before specifying a direct-view LED wall. The calculator above answers the geometry; this sub-page answers the engineering judgement around it.

How do I choose between LED wall and projection / LCD video wall?

Three discriminators: pixel pitch / viewing distance match, ambient light, and lifecycle. LCD video walls (Samsung VHQR, LG VH7E series) carry visible bezels every ~500mm — fine for static dashboards but distracting for video content. Projection (single projector + screen, or projector blending) is cheaper for cinematic single-image use but loses to ambient light. Direct-view LED is the right answer when you need a seamless image AND the room has ambient light AND the viewing distance is appropriate to a sensible pitch. Below 100″ effective diagonal at <3m viewing, LCD or projection usually wins on cost. Above 130″ with ambient light, LED wins. Above 250″, LED dominates.

What is the pixel-pitch rule of thumb, and why is it not exact?

The 'pitch × 1' rule says: pitch in mm = optimal viewing distance in m. So a P2.5 wall is optimal from 2.5m back. This is the floor — pixel structure becomes acceptable at this distance. For text-dense content (trading floors, command centres) push tighter — pitch × 0.7. For premium broadcast where the audience scrutiny is intense, push to pitch × 1.5. For cinema-style content where the viewer is engaged in story not detail, pitch × 2.0-2.5 works. The calculator's content-type selector encodes these ranges; the warning fires when the configuration falls outside the appropriate band.

MicroLED vs MiniLED vs SMD LED — what do the labels actually mean?

Three implementations of direct-view LED. SMD (Surface-Mount Device) packages three discrete R/G/B LEDs in a single small package mounted on a PCB — the workhorse for pitches above ~1.5mm. MiniLED uses smaller LED chips (typically 100-200 µm) for pitches around 0.9-1.5mm — used by Samsung The Wall IWA, LG MAGNIT LSAA. MicroLED uses sub-100µm chips with mass-transfer assembly — used in Samsung The Wall IWA (some variants), Sony Crystal LED. The labels matter for: (1) sub-pixel uniformity (MicroLED is best), (2) burn-in resistance (MicroLED is best), (3) cost (SMD is cheapest, MicroLED is most expensive), and (4) HDR peak brightness ceiling (MicroLED reaches highest). For most premium installations in 2026 the distinction matters less than brand-execution discipline.

What about Aero Digital, domestic Indian OEMs and other brands not in the database?

v1 of the database carries 9 international brands. Domestic Indian OEMs (Aero Digital, others) and rental specialists are explicitly excluded pending verified datasheet collection — we will not commit half-verified data and degrade the trust the calculator exists to build. If you have a project requiring a brand not in the list, send the brand and the datasheet via /contact; the editorial pass adds verified brands in batches. Our specification work routinely includes Indian-manufactured LED for cost-sensitive projects, but always with verified module-level data before we commit.

Why does the calculator separate average and peak power?

Because the difference is structural for electrical planning. Average power (~200-260 W/m² for fine-pitch indoor) is what the utility bill reflects. Peak power (450-600 W/m² for the same panels) is what you provision for circuit breaker sizing, UPS capacity and cable AWG selection. Sizing the circuit for average and then driving a bright HDR scene at peak demand trips the breaker. Always provision the electrical to the peak figure with 20% headroom.

What is the realistic 10-year operational pattern?

Year 0-2: commissioning curve, processor firmware updates, sub-pixel calibration. Some module replacement during burn-in. Year 3-5: stable performance; 1-2% module replacement rate is normal. Year 6-10: cumulative module replacement reaches 5-8%; manufacturer typically end-of-lifecycles the model in this window. Year 11+: spares availability decays — replacement modules become expensive and visually mismatched. Plan: hold 3-5% spare modules at project inception, plan a processor refresh at year 5-7, budget partial recabinet at year 12-15 if the wall is heavily used. The cabinets themselves outlast their processor by 2-3x.

What additional engineering does a virtual-production / XR LED wall need beyond a normal video wall?

Three layers. (1) Higher refresh rate — 7,680 Hz+ for camera tracking without scan banding (Barco XT, Roe Visual Black Pearl class). (2) Calibration to the camera's native gamut and white point — done at integration time using the camera, not just the eye. (3) Processor capable of frame-genlock to the camera and the LED scan; integrated with the camera tracking system (Mo-Sys, stYpe). Virtual production is a different specification problem from boardroom or broadcast walls — the calculator surfaces the refresh-rate flag but the rest is in conversation.
