Both spellings are correct. The choice between modelling and modeling comes down to where you are — or where your audience is.
The Short Answer
Modeling — one L — is standard in American English.
Modelling — two Ls — is standard in British, Australian, and Canadian English.
Neither spelling is wrong. They are regional variants of the same word.
Why the Double-L Confusion Exists
English has a rule about doubling a final consonant before adding a suffix like -ing or -ed. In most cases, you double the consonant when the stress falls on the final syllable of the base word.
The word model is stressed on the first syllable: MOD-el.
By the standard rule, the final l should not be doubled — and in American English, it isn’t. So Americans write modeling, modeled, modeler.
British English historically ignored that rule for words ending in -el and doubled the l regardless of stress. So British writers use modelling, modelled, modeller.
This same pattern shows up in other words:
| Word | American English | British English |
| model | modeling | modelling |
| travel | traveling | travelling |
| cancel | canceling | cancelling |
| label | labeling | labelling |
| fuel | fueling | fuelling |
The pattern is consistent. If you know one, you know them all.
Which Should You Use?
Use the spelling that matches your audience.
Use modeling if you’re writing for an American audience — in U.S. publications, American websites, or documents following American style guides like AP or Chicago (American edition).
Use modelling if you’re writing for a British, Australian, or Canadian audience — in UK publications, Commonwealth websites, or documents following British style guides.
If you’re unsure of your audience, either form is acceptable. Just be consistent within a single document. Don’t switch between the two.
The Word Itself — What Does It Mean?
Both spellings cover all the same meanings. Modeling (or modelling) refers to:
- Working as a fashion or commercial model: She has been modeling since she was eighteen.
- Creating a three-dimensional representation: The architects spent weeks modeling the new building.
- Building a scientific or mathematical model: Researchers are modeling the spread of the disease.
- Demonstrating behavior for others to follow: Teachers often model good reading habits for their students.
- Shaping a material like clay: He was modeling the figure out of wet clay.
The meaning never changes based on spelling — only the geography of the writer does.
A Note on Compound Terms
In technical and creative fields, the one-L or two-L rule follows the same regional logic:
- 3D modeling / 3D modelling
- data modeling / data modelling
- financial modeling / financial modelling
- role modeling / role modelling
If your field has a house style — many engineering, finance, or scientific publications do — follow that style consistently.
Quick Rule to Remember
One L → One country (the U.S.)
Two Ls → The rest of the English-speaking world
Both modeling and modelling are fully correct. Pick the one that fits your audience, and stick with it.
