Less than 20' is fine, but it will limit the production of your hops. The first two years that I grew hops, I was working with a 12' trellis. I then upgraded to what I have now. It's a 15' trellis, but I can adjust it higher or lower. Lower for harvesting, higher when my hops need extra room. Last year, I extended it to 20' for the entire grow season...the year before it was 15'.
Now...it could be the fact that my hops have a better root structure after the extra year...but I noticed that when I extended to 20', my hops produced about 25% more. Plus, they weren't as bushy because they didn't have to expand outward as much. This made it a lot easier to keep them seperated between different varieties.
