This can vary due to the individual peculiarity of an instrument such as string weight, scale length, etc. A more involved method of testing is to deliberately cause a string to buzz by extra hard plucking. If a buzz is produced from all of the frets, then the amount of neck relief is probably correct. All that's needed in that case is a small amount of bridge adjustment to suit the individual style of playing. An insufficient amount of relief or a warped neck will cause buzzes in the lower positions nearer the nut.
String buzzing in the higher positions can indicate too much neck relief or a warped neck.
Remember though, string tension can cause the neck to pull upward. If you encounter no buzzing at all, then the bridge may be lowered if you prefer a lighter action. However, the table below reflects standard guidelines. Light strings and light playing require less relief and heavy strings and heavy playing need more relief. Short scales need less relief and long scales require more.
