Main Difference
The main difference between Shape and Size is that the Shape is a form of an object or its external boundary and Size is a magnitude or dimension of a thing; concept abstracted from the process of measuring by comparing a longer to a shorter
Shape
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture or material composition.
Psychologists have theorized that humans mentally break down images into simple geometric shapes called geons. Examples of geons include cones and spheres.
Size
Size is the magnitude or dimensions of a thing. Size can be measured as length, width, height, diameter, perimeter, area, volume, or mass.
In mathematical terms, “size is a concept abstracted from the process of measuring by comparing a longer to a shorter”. Size is determined by the process of comparing or measuring objects, which results in the determination of the magnitude of a quantity, such as length or mass, relative to a unit of measurement. Such a magnitude is usually expressed as a numerical value of units on a previously established spatial scale, such as meters or inches.
The sizes with which humans tend to be most familiar are body dimensions (measures of anthropometry), which include measures such as human height, and human body weight. These measures can, in the aggregate, allow the generation of commercially useful distributions of products that accommodate expected body sizes, as with the creation of clothing sizes and shoe sizes, and with the standardization of door frame dimensions, ceiling heights, and bed sizes. The human experience of size can lead to a psychological tendency towards size bias, wherein the relative importance or perceived complexity of organisms and other objects is judged based on their size relative to humans, and particularly whether this size makes them easy to observe without aid.
