What is Albert Einstein's IQ?
Albert Einstein's IQ is usually given as 160. He never took an IQ test. The number was invented after his death and has been repeated so often that it now reads as fact, which is a good illustration of how these figures actually spread.

A quick, honest note. This number circulates online with no traceable origin. We publish it because you came to read it, and label it what it is: lore.
Where does the 160 number come from?
Einstein died in 1955. Widespread IQ testing of adults was not a thing he was ever subjected to, and no record of any test exists.
So where does 160 come from? Largely from circularity. Einstein is the culturally agreed reference point for genius, 160 is a culturally agreed number for genius, and at some point the two were welded together in a magazine listicle. The figure is now quoted in classrooms, on quiz sites, and in advertising copy for brain-training apps.
You will also see 205 and 225 attached to him, produced by retrospective "historiometric" estimates that score dead people from their biographies. Those methods have obvious problems: they are essentially rating fame and productivity, then converting the rating into an IQ-shaped number.
The honest answer to "what was Einstein's IQ" is that nobody knows and nobody can know.
How rare would a 160 IQ be?
If the 160 figure were literally true, it would be extraordinarily rare — rarer than1 in 31,560 people. That alone is a good reason to treat any confident-sounding celebrity IQ number with a raised eyebrow.
Too rare to draw — a grid with one highlighted dot in 31,560 would be a solid wall of gray.
What a score like this would mean
A 160 would sit in the very superior · gifted range — about one person in 31,560. Fill a large concert hall and you would expect nobody in the room to clear it.
Stop reading estimates about strangers. Sixteen questions and about ten minutes gets you a number that is actually yours.
Frequently asked questions
What was Albert Einstein's IQ?
Unknown. He never took an IQ test. The commonly quoted 160 has no documented source.
Why is 160 always given as his score?
It appears to be circular: Einstein is shorthand for genius, 160 is shorthand for a genius score, and the two were joined in popular lists long after his death.
Are the estimates of 205 or 225 any better?
No. Those come from retrospective methods that score historical figures from biographical records, which largely measures eminence rather than reasoning ability.
