Picture Hanging Position Finder And Wall Marking Device has an elongated adjustable vertical support with a hanger at the top to accept and hold a wire or bracket for a framed picture or other hanging object, wherein the device may lean against a wall with the back of the vertical support held flush against the wall, and with the bottom of the vertical support elevated above any wall baseboard, and held in place by forward and laterally extending legs which reach down to a horizontal floor. As such, a picture can be suspended from the vertical support, and the device can be moved to any location against a wall, and the height can adjusted and locked in place, so that a user may view the picture from a distance as if it were hung on the wall in order to choose a desirable location for the picture. The device then has a means for marking the wall for the installation of a permanent hanger at the precise location from where the picture had been temporarily suspended.
