A:Answer 7ft x 3ft x 2ft. Unless you have a wide/large stairwell or outside access, you will not be able to get it to a basement. Highly recommend you read my review before opting to have Best Buy deliver. Opted for this one given treadmill guru’s comparison reviews - has fan (Peloton doesn’t), workouts that adapt with you according to how your abilities improve (Peloton doesn’t), better cushioning for knees and joints (compared to mult others). To me the treadmill is worth it (haven’t used — stuck in box, see review), just beware of how Best Buy will handle it.
