I made a post about this, but a thread might be better for the search function on the website to see it better.

This is work done by phoenix12 on Tamrielfoundry.com. I am just formatting it.


Without Racial or Armor bonuses:
o Detection radius is approximately 4m when directly behind an enemy. (closer than this results in being detected)
o Detection radius is approximately 15m when directly in front of enemy. (Closer than this results in being detected)
o Detection radius describes the radius the target can see you, ie…this radius emanates FROM target.

With Medium Armor Bonuses
o Detection radius is approximately 2.6m when directly behind your target. (4m minus 35%)
o Detection radius is approximately 9.75m when directly in front of enemy. (15m minus 35%)
o Basically, this bonus reduces your targets detection radius.

With Racial and Medium Armor bonuses
o Detection radius is approximately .65m when directly behind target. (4m-3m minus 35%)
o Detection radius is approximately 7.8m when directly in front of target. (15m-3m minus 35%)
o These bonuses do stack, the racial bonus pushes against their detection radius.

These numbers are not offical from Zenimax, however Phoenix12 did do extensive testing to come up with em.

Thanks Phoenix12 for the work on this.
