An image of an environment including an object (i.e., object in reality, physical object) can be captured and be displayed by a computing device. The size of an image representation of the object can be determined. Information about a physical size of the object and about a distance between the computing device and the object in the environment can be obtained/determined. A comparison of the size of the image representation of the object and the physical size of the object can be used to calculate a scale for converting between an actual size of a real-world item and a size of the item as displayed. The information about the distance can optionally be used to determine/adjust/modify the scale. A virtual article depicting/representing a real-world article/item/object (i.e., real-world correspondence) can be displayed with the captured image. The virtual article displayed can be scaled to an appropriate size using the scale.
