Step 1 — The venue dictates the wall
Walk the room (or the floorplan). The wall lives behind the stage; mark its maximum width and height in feet. Note the ceiling, the trim height of any rigging, and the distance from the front row of seats to the stage face.
Rule of thumb: the wall should be 80–120% of stage width and 9–14 feet tall. Bigger looks impressive in renders, but the human eye stops perceiving more screen real estate beyond a certain ratio of viewer-to-screen — and the bigger you go, the harder content becomes to design without it looking like a sports broadcast.
Step 2 — The front row dictates the pitch
Pixel pitch (the LED-to-LED distance, in mm) drives sharpness. The closer your front row, the finer the pitch needs to be — or individual LEDs become visible.
- Front row 10 ft+ away → 4–6 mm is fine
- Front row 5–10 ft away → 2.5–4 mm
- Front row < 5 ft (cocktail / theater-in-the-round) → < 2.5 mm
- Camera-facing wall (any IMAG / live-stream)? Always go finer — cameras zoom.
Step 3 — The lighting designer dictates the brightness
Stage lighting spills onto the wall. If the lighting designer is running 3 000+ lux on the deck for camera, your wall needs to be brighter than the room, or it disappears. Indoor corporate events typically need 1 500 nit; if the LD is running heavy, 2 000+.
Step 4 — The content drives the processor
Single-screen video at 1080p? A basic image processor is fine. Two side-by-side 4K feeds with a center scrim and a confidence monitor? You need a real video processor with at least 8.3 megapixels of canvas and 4K60 input on every port.
For broadcast / IMAG, your content engine must be genlock-ready. Without it, you'll get scan banding on camera. This isn't optional.
Step 5 — The budget envelope
For rough sizing, plan on:
- $1 200 – $2 000 / m² rental for fine-pitch indoor (1.95–2.6 mm) for a 3-day event, including processing, road cases, and on-site tech.
- $3 500 – $6 000 / m² purchase for fine-pitch, plus 15–20% for processors, mounting, and commissioning.
- Budget another 10–15% of the panel cost annually for service, calibration, and spares.
Step 6 — Write the spec
A real LED spec line for an RFP looks like:
Indoor LED wall, fine-pitch ≤ 2.6 mm, ≥ 1 500 nit, 7 680 Hz refresh, HDR-10 capable, with image processor supporting ≥ 4K60 input and ≥ 8.3 megapixel canvas. Wall: 24 ft W × 12 ft H. Genlock-ready. Includes road cases, mounting, on-site tech, pre-event calibration check.
That's it. That's an LED spec. Three sentences. Hand it to two AV bidders and you'll get apples-to-apples quotes.
