trellis spacing

[Chic Rustler]

What's the spacing needed for a 16 foot 50 inch tall trellis for things like green beans and cucumbers? Like how many can I plant on it?

The limiting factor is ventilation and "mildew" growth on the plant. I do peas 6" apart, double rows, about 4" apart - one on each side of a trellis panel. If peas were a longer season plants it would kill them. They're dying off about when they're done bearing pods, sometimes reducing our yield. We just plant more peas.

I've never trellised cucumbers. I think they would need quite a bit of space!
