What pixel pitch do I need for outdoor LED walls?

Outdoor LED used to mean big, coarse pixel pitch because that was the only way to get weather durability. That's changed. Today, outdoor-capable tiles are available in the 3mm to 8mm range with full IP65 ratings and high brightness (4,000-6,000+ nits compared to around 1,000 nits for typical indoor panels). 

4Wall stocks several IP65-rated outdoor options: the Planar Leyard LN 3.9S Outdoor (3.9mm) at roughly 4,000 nits for fast-rig curved walls; the ROE Carbon CB5 (5.77mm) at up to 6,000 nits in a carbon fiber touring frame; the Chauvet F5IP (5.9mm) at around 5,000 nits calibrated with wide 160°/155° viewing angles; and the ROE Carbon CB8 (8.33mm) for massive sightline screens at 5,000 nits. Choose your pitch based on how close your audience or cameras will be.
