- •
We identify the origin of glass forming ability enhanced by atomic size difference.
- •
We examine changes by quantitatively separating the kinetic and thermodynamic contributions.
- •
Larger atomic size differences are found to improve glass forming ability.
- •
Role of atomic size difference is not necessarily to promote kinetic suppression through effective packing.
- •
Atomic size difference could influence GFA by introducing local strains.
