When comparing moulding vs molding, both spellings are correct. The main difference is regional spelling. Moulding is the standard spelling in British English and is commonly used in the UK and other varieties influenced by British English. Molding is the standard American English spelling. Both words can refer to the process of shaping a material or to a decorative or structural piece made by shaping material.

Understanding this distinction helps you choose the spelling that matches your audience, location, or style guide.

Choose one spelling system and maintain it.

The same regional distinction applies to the base word:
- British English: mould
- American English: mold
Therefore:
- British English: moulding
- American English: molding
