Is oil a short vowel or a long vowel?

Answer 1

The most common pronunciation of "oil", [ɔːjl̥], has one vowel which is considered "long" by phonetic / linguistic convention (actual length of the vowel). English "long" and "short" vowels are somewhat different; this vowel would probably be considered a "short O". Which makes things really confusing, because the vowel is now a "long short O" if you combine the systems.

*Usually this OI/OY sound is not considered long or short, but you can see by pronouncing the OY that it is clearly a triphthong of the long vowels "O-I-E."

It is seen in words such as boy, boil, toy, toil, noise, coin, and point.

Answer 2

Short
