Prepositions – Correct Preposition for ‘Perfect Fit’

prepositions

I would like to polish my text and am not sure what would be the proper use of preposition in this phrase:

The idea of event loop is a perfect fit to the basic Arduino concept.

or

The idea of event loop is a perfect fit in the basic Arduino concept.

Context: there is a software solution that uses event loop as its main execution block and this fits perfectly (in/to) the concept of infinite loop used in every Arduino program (the infinite loop is an inseparable part of every program in Arduino framework).

Let's compare examples culled from Google search:

  • "perfect fit for": "the role", "your team", "your personality", "Brides & Grads", "Careers"
  • "perfect fit to": "baby ear soft infant headphone", "Buffet's 10xEBT Rule", etc. but the majority is "perfect fit to verb" such as "perfect fit to maximize", "perfect fit to replace", etc.
  • "perfect fit in: "jeans", "swimwear", "Men's Tailoring, but the majority is "perfect fit in place / language" such as "perfect fit in real life", "perfect fit in English", "perfect fit in Los Angeles"
  • "perfect fit with:" "brackets", "the flap", "Temp Staffing", "Jabra motion", "a variety of sizes", "Weight Watchers"

As you can see above,

  • "for" is used when referring to a purpose, people, or a social function
  • "to" is used when referring to a concrete thing
  • "in" is used when referring to something you wear, a location, or a language
  • "with" is used when referring to something you use together

Based on the analysis above, and knowing the programming technique you are talking about, I think the best preposition would be "with", since you use the technique together with the concept of the Arduino hardware that is designed for real-time, event-driven controller projects.

But if you want to emphasize the purpose then you would use for, meaning a programming technique for the Arduino hardware.
