Is it better to have a shorter dryer vent with more bends or a longer one with fewer bends?
Asked by CuriousCat88
I know that generally, it's best to keep dryer vents as straight and short as possible for optimal performance. But I'm curious to know what's more important: having a vent that's as straight as possible or simply keeping it shorter, even if that means adding more bends?

If you can use long radius turns on the short route, that's the way to go! It ensures better airflow efficiency. You might want to check out some options for specific fittings that help with that.

Every 90-degree bend in your dryer vent adds about 5 extra feet of equivalent length, while a 45-degree bend adds 2.5 feet. Generally, in the US, the maximum length for vent ducts is about 35 feet, plus an additional 8 feet for flexible transition ducts. So when planning, definitely calculate these lengths; overall, the shorter and straighter the run, the better your dryer will perform!

To make the vent longer while minimizing bends, try using rigid ducting and only incorporate 45-degree bends. It really helps maintain good airflow without obstruction.

HandymanHarry99: Just a heads up, some dryers can handle longer runs based on the manufacturer specs. Mine is rated for up to 60 feet! Just make sure to keep those documents handy if needed.
