I'm working on some code that maps data across the continental US.

I need to project things with a unit length of feet, ex: EPSG:26916.

Is there a projection like 26916 that works for all of the US?

As far as I can tell there are longitude limits for accuracy with 26916.

    As a starting point, check here: gis.stackexchange.com/questions/141580/…. Choosing a projection is quite a broad topic, and often there is no "correct" answer. It usually boils down to whether you want to preserve distance, shape, angle, or can be satisfied with a compromise.

    That's UTM - definitely not appropriate for the continent. UTM is poor choice usually, but we have to align with it because so many local authorities adopted it long ago. More discussion geocompr.robinlovelace.net/…

I'd start with EPSG:2163 aka US National Atlas equal area, this fulfils all of your needs except it is in metres not feet. But that is a simple multiplication fix (unless you are NASA).
