Around 10–12% of people are left-handed worldwide, meaning roughly 1 in 9 to 1 in 10 people.

Quick Scoop

  • Most large studies and reviews report that about 10% of the global population is left-handed.
  • More recent summaries aimed at the general public often put the figure a bit higher, at around 12% , suggesting left-handedness may be slightly more common than older estimates indicated.
  • The remaining majority is right-handed (around 87–90%), with a small minority (about 1%) considered truly ambidextrous.

Why the Range (10–12%)?

Researchers use different definitions (writing hand only vs. multiple tasks), survey different countries, and collect data at different times, so published estimates vary slightly. Social acceptance also plays a role: in places and eras where left-handedness was discouraged, fewer people reported or displayed it openly, which pushed older estimates downward.

So if you’re left-handed, you’re part of a relatively small but very noticeable minority — rare enough to be interesting, common enough that you probably know several other left-handers.

TL;DR: Expect any good modern source to say that about one in every ten people is left-handed, sometimes updated to “about 12%” as a more precise current estimate.
