When you want to know whether someone is interested in an idea, product, event, or opportunity, you might say you’re gauging interest. But because gauge has an unusual spelling, many people wonder whether gaging interest is also correct.
So, in the debate over gauging interest vs gaging interest, which spelling should you use?
The standard and overwhelmingly preferred form is gauging interest. It comes from the verb gauge, meaning to estimate, measure, or assess something. While gaging can occasionally be found as a variant spelling, it is uncommon and can look like a spelling mistake to most readers.
If you’re writing an email, article, report, business proposal, or social media post, gauging interest is the safest choice.
