What is the difference between はみ出す and はみ出る?


They are both intransitive:

> シャツがズボンから **はみ出しています** よ。 Your shirt is coming out of your pants.
>
> 足が 線から **はみ出ています** 。 Your foot is over the line.




Those two verbs are almost the same. I checked the first 100 examples of "はみ出"
on BCCWJ, and はみ出す and はみ出る were interchangeable **except** :

  * はみ出る is less commonly used in the form of bare masu-stem, はみ出 (either as a noun or a replacement of te-form to continue a sentence). Although one-character masu-stems (見【み】, 来【き】, 寝【ね】) are less common before a comma in general.

> ここのはみ出し【だし】部分が気になる。: OK  
>  ここのはみ出【で】部分が気になる。: Less common
>
> シャツがはみ出し【だし】、だらしない恰好になっている。: OK  
>  シャツがはみ出【で】、だらしない恰好になっている。: Less common

  * はみ出し also has a meaning of "misfit", "outlaw", etc (はみ出し者, はみ出し野郎, ...). In this sense, はみ出者 is not wrong but less common for some reason.
