The difference between "molding" and "moulding" lies in their spelling and usage.
- Molding is the preferred spelling in American English.
- Moulding is the preferred spelling in British English.
Both spellings refer to the same thing: a decorative or structural element that is shaped and formed using a mold.
Here are some examples:
