Moulding vs. Molding: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on November 9, 2023
Moulding and molding are different spellings of the same word; "moulding" is British, and "molding" is American, both refer to the process of shaping a pliable material.

Key Differences

Moulding, in British English, and molding, in American English, describe the act of forming something into a particular shape. The usage of moulding versus molding does not alter the basic definition of the term, which is the process of shaping a fluid or malleable material using a rigid frame called a mold. In both cases, the term can refer to a strip of material with various profiles used for decoration on walls, ceilings, or furniture.
The term moulding is used in various contexts in British English, ranging from the act of shaping clay in art to the process of forming plastics in manufacturing. Similarly, molding in American English encompasses these same contexts. The spelling difference does not denote a difference in meaning but rather reflects a variance in regional spelling conventions.
In the construction and manufacturing industries, moulding often refers to decorative strips and architectural accents in British contexts, whereas molding in American contexts would carry the same meaning. The terms are interchangeable in practice, with the choice of spelling being the only difference.
The process of creating a mould/mold itself is also denoted by these terms. Moulding in British English and molding in American English can both refer to the process of creating a cavity or form that shapes liquid or semi-liquid substances into a fixed design as they solidify.
Moulding and molding can both be used as nouns to describe the result of this process. Whether it's a moulding on a picture frame or a molding on a piece of classic American architecture, the words describe the finished product that has been shaped from a material using a mold.
