The Size property determines the dimensions of a part. The individual dimensions can go as low as 0.05 and as high as 2048 (or 2^11). The size of the part is used in determining its mass, which is given by
/BasePart/Shape of a part can apply some restrictions on Size - namely, a Ball must have the same 3 dimensions. A part’s Size is used by a variety of other objects:
/ParticleEmitteruses Size to determine the area from which particles are spawned.
/BlockMeshuses Size to partially determine the rendered rectangular prism.
/SpecialMeshuses Size for some certain
/SpecialMesh/MeshTypes to determine the size of the rendered mesh.
/SurfaceLightuses Size to determine the space to illuminate.
This code sample constructs a pyramid by stacking parts that get progressively smaller. It also colors the parts so they blend between a start color and end color.
