Modelling vs. Modeling | Meaning, Spelling & Examples

Modelling and modeling are two different spellings of the present participle of the verb “model” (and the identical gerund) used to mean “display by wearing or posing” or to refer to the act of creating a representation or imitation of something.

The spelling tends to vary based on whether you’re using UK or US English:

  • In US English, “modeling” (one “l”) is correct.

  • In US English, “modeled” is correct.
