Moulding vs Molding – Quick Answer
Both moulding and molding refer to the same thing: a strip of material (wood, plaster, or plastic) used for decorative or functional trim in buildings.
- Moulding → British English spelling.
- Molding → American English spelling.
Example:
- UK: “The carpenter installed ornate moulding along the ceiling.”

The Origin of Moulding vs Molding
The word comes from the Latin modulus, meaning “measure.” Over centuries, it passed through Old French (moldure) before entering English.
- British English kept the older form with “u” → moulding.
- American English simplified it by dropping the “u” → molding.
This difference follows a larger spelling trend (colour vs color, honour vs honor, etc.) shaped by Noah Webster’s dictionary reforms in the 1800s.
British English vs American English Spelling
The main difference is spelling preference:
| Word | British English | American English |
| Colour/Color | Colour | Color |
| Honour/Honor | Honour | Honor |

Rule of thumb: British English often keeps the “u,” while American English removes it.
