The numbers that matter
Cheap consumer kits run roughly 6-inch pitch. Older pro systems are 4-5 inch. The Jellyfish RGBIC-RD that we install is roughly 4-inch pitch, which is at the high-density end for outdoor.
Indoor strips can go down to 1-inch pitch, but you'd never use that outside — the heat dissipation isn't workable.
What you'll see at the curb
At 6 inches you can count individual dots from the sidewalk during a gradient. At 4 inches the gradient looks like a continuous wash. The difference is most visible in animations — chase patterns, Christmas twinkle, fire effect.
Where it's hidden in the spec sheet
Most brands don't print pixel pitch on the consumer-facing page. Ask your installer directly: 'What's the pixel-to-pixel spacing?' If they don't know, that's a tell.
