Can I use a projector in daylight?

Only ultra-bright projectors (3000+ lumens) are visible in daylight, and even then the image is washed out. Plan outdoor screenings for dusk or later. A shaded area extends usable hours.

How big should an outdoor screen be?

100 inches (about 8 feet wide) is the sweet spot for backyard viewing from 10-15 feet away. Any larger and brightness suffers. Any smaller and people in the back have trouble seeing.
