Ever typed out a sentence and hit the brakes on this spelling dilemma: Is it modeling or modelling?
You’re not alone. This is one of those deceptively simple spelling questions that reveals how regional English differences can sneak into everyday writing. Whether you’re drafting a resume, editing a product description, or coding a 3D rendering script, the form you choose modeling or modelling can say a lot about where you’re from and who you’re writing for.
So let’s settle this once and for all.
Modeling vs. Modelling: Keyword + Intro Explanation
Let’s get the big question out of the way: Both modeling and modelling are correct spellings of the same word.
Here’s the difference:
- Modeling (with one “L”) is the spelling used in American English.
- Modelling (with two “L”s) is the spelling used in British English, Canadian English, Australian English, and other Commonwealth countries.
It’s a classic case of US spelling vs UK spelling like traveling vs travelling or labeled vs labelled.
Simple Definition + Usage Overview
To model means to create, represent, or demonstrate something whether it’s behavior, clothing, a concept, or a structure. The verb can refer to fashion modeling, behavioral modeling, or data modeling. Regardless of context, the action is the same only the spelling changes depending on your region.
Clear Rules & Patterns
Here’s a quick cheat sheet to help you choose the correct form based on region:
| Region | Correct Present Participle | Past Tense | Noun Form |
|---|---|---|---|
| 🇺🇸 United States | modeling | modeled | modeler |
| 🇬🇧 United Kingdom | modelling | modelled | modeller |
| 🇨🇦 Canada | modelling | modelled | modeller |
| 🇦🇺 Australia | modelling | modelled | modeller |
Why the difference?
The answer lies in the L-doubling rule. In British spelling, a single-syllable verb ending in a vowel + consonant like “model” usually doubles the final consonant before adding suffixes like –ed or –ing. American English generally avoids doubling the “L” unless the last syllable is stressed (as in “propel” → “propelled”).
Bulleted Rules with Do’s and Don’ts
✅ Do:
- Use “modeling” in U.S.-based writing (academic papers, job applications, tech documentation).
- Use “modelling” when writing for UK, Australia, Canada, or global brands that use British English.
- Be consistent stick to one version throughout your document.
❌ Don’t:
- Mix both spellings in one document.
- Assume one form is a typo both are grammatically correct.
- Use British spelling in U.S. business settings unless your audience expects it.
Multiple Example Sentences
Let’s explore both spellings in realistic contexts.
✦ American English:
- “He’s interested in modeling machine learning algorithms to predict customer churn.”
- “Claire recently signed with a New York agency to pursue a career in modeling.”
- “We hired a 3D modeler to help us design our new product prototype.”
✦ British English:
- “The course covers advanced financial modelling techniques for analysts.”
- “Sophie began modelling for a London-based fashion house at age 16.”
- “The architecture firm employed a seasoned modeller to bring the blueprints to life.”

Subject: Request for 3D Modeling Proposal
Hi Marcus,
As discussed in our last meeting, we’d like to explore options for integrating 3D modeling tools into our workflow. I’ve attached an outline of the features we’re looking for.
Could we schedule a call to review the technical requirements this week?
Best regards,
Dana

Subject: Behaviour Modelling Pilot Results
Dear Dr. Hayes,
Following our recent trial, I’ve compiled data on the impact of behaviour modelling in Key Stage 2 classrooms. The early indicators are promising, especially in social-emotional learning.
Please let me know if you’d like the full report.
Kind regards,

Before/After Examples in Common Contexts
| Context | Incorrect (Mixed) | Correct (US) | Correct (UK) |
|---|---|---|---|
| Resume entry | “Experienced in modelling.” | ✅ “Experienced in modeling.” | ✅ “Experienced in modelling.” |
| Tech documentation | “Modelling APIs for scalability.” | ✅ “Modeling APIs for scalability.” | ✅ “Modelling APIs for scalability.” |
| Blog post on fashion | “Modeling campaigns worldwide.” | ✅ “Modeling campaigns worldwide.” | ✅ “Modelling campaigns worldwide.” |
Common Mistakes & Fixes
| Mistake | Why It’s Incorrect | Corrected Version |
|---|---|---|
| “I’m modelling data pipelines.” (in US context) | Uses UK spelling in American context | “I’m modeling data pipelines.” |
| “The behaviour modeling approach.” (in UK context) | Mixed spelling styles | “The behaviour modelling approach.” |
| “He’s a famous modeler in France.” (in UK) | American noun used in British English | “He’s a famous modeller in France.” |
Quick Reference Table: Modeling vs Modelling
| Spelling Type | Present Participle | Past Tense | Noun Form | Used In |
|---|---|---|---|---|
| American English | modeling | modeled | modeler | USA, Philippines, South Korea |
| British English | modelling | modelled | modeller | UK, Canada, Australia, India |
Why the Difference Exists (Etymology)
The origin of the word “model” can be traced back to:
- Latin: modulus, meaning a small measure or standard
- Italian: modello
- French: modèle
The variation in spelling emerged from Noah Webster’s efforts to simplify and standardize American spelling in the 19th century. He preferred phonetic simplicity, which is why Americans dropped the extra “L” in words like modelling, travelling, and labelled.
Spelling Differences in Similar Words
| UK Spelling | US Spelling |
|---|---|
| modelling | modeling |
| travelling | traveling |
| labelled | labeled |
| cancelling | canceling |
| signalled | signaled |
These words follow the same orthographic pattern: L-doubling in UK spelling, single L in US spelling.
Final Thoughts: Is the Right Word Modeling or Modelling?
Here’s the verdict:
- Use “modeling” when writing for an American audience or using US English standards.
- Use “modelling” for British or Commonwealth contexts.
- Always stay consistent within your document.
- Consider your audience, medium, and purpose when choosing the form.
