There is no legal definition of “midget” in the usual sense. The term is widely considered derogatory , and the respectful/accepted term is “person with dwarfism” or “little person.”

What’s actually used

  • Dwarfism is commonly defined medically as an adult height of 4'10" (147 cm) or shorter , though diagnosis depends on medical or genetic conditions, not just height.
  • “Midget” is not a modern legal category; it’s an outdated term that many people find offensive.

Short answer

If you’re asking “at what height are you legally a midget?” the answer is: there isn’t one. In practice, laws and medical classifications talk about dwarfism or short stature , not “midget.”

Better wording

If you need to describe this respectfully, use:

  • person with dwarfism
  • little person
  • person of short stature

If you want, I can also explain the difference between dwarfism , short stature , and the old term midget in one simple table.
