A portable postal scale for determining whether the weight of a letter exceeds the maximum for a given amount of postage, for example, one ounce. The scale comprises an elongated beam having a letter holder, a fulcrum, a leveling assembly and a preloaded portion and a wedge shaped piece. The letter holder comprises two upward facing arms forming a narrow slot for holding the letter to be weighed in an upright position. The leveling assembly, which allows the scale to be used on an unlevel surface, comprises a leveling bubble with scribe lines. The portion of the beam from the fulcrum to the end opposite the letter holder is the preloaded portion that has sufficient weight to balance the beam when a letter of predetermined weight is placed in the letter holding slot. In use, the end of the beam opposite the letter holder is placed on top of the wedge shaped piece, which is moved forward or backward until the leveling assembly is level. Tipping indicates that the weight of the letter is greater than the predetermined amount.
