Check https://theultimatehang.com/hammock-hang-calculator/ for important physics/geometry checks in helping place the anchors. Note how tighter, flatter pitches greatly increase the stress/danger on suspension and structure. So you want the suspension to be relaxed/saggy. In general, hanging points that are higher and farther apart than necessary are better than those that are too low or close, because you can make up the difference with varying suspension lengths. Also you can walk under high drooping suspension: not so much if the mounts are below head level on one or both sides. So it starts with your hammock length. Gathered end types are superior in comfort, practicality, and gentle structural hanging requirements. The calculator will tell you roughly where to put the mounts to give you a relaxed (30° or steeper) hang, with the low point of the hammock at a comfortable sitting height. If there are no studs or joists at those points, pick the nearest along the same lines that are farther or higher than the ideal spots. Unless you have reason to suspect shoddy construction, it's pretty safe to anchor into studs or joists, as long as you are sure that you're near the centers of those elements. Assuming they are covered by drywall/plaster, this requires making numerous small pilot holes to discover the edges, then you know where the middles are.
