The Standard Poser Scale Unit is equal to 8 feet (96 inches). If you model in a program that uses 1 Unit = 1 Foot then your object will come into poser 8 times as large as you would expect. If you use a program that models in inches, it will come into Poser 96 times bigger than it should. Most programs use inches, centimeters or Meters as their standard unit (and they allow you to specify the units if you wish). When you are finished modeling, and ready to export your OBJ, just do a 3D scale centered on 0,0,0 of the GLOBAL axes (not the object axes because this will cause your object to com into poser Waaaaay off center - so scale on the global 0,0,0). The factor you should use is 1/96 for inches or as decimal it is .0104167 and as a percent (some systems scale by percent rather than as a decimal factor) it is 1.04167%. Then import the OBJ into Poser with NOTHING checked and your object will be PRECISELY scaled AND in the proper position in the scene.
