Is an IQ of 139 Good? What It Means & Where You Stand

What Does an IQ of 139 Mean?

An IQ of 139 is deep in the gifted range, just one point below the commonly cited genius threshold of 140. At the 99.5th percentile, only about 1 in 185 people score this high. The distinction between 139 and 140 — 'gifted' vs 'genius' — is entirely arbitrary and has zero practical significance. You are effectively at the genius boundary.

An IQ of 139 places you at the 99.5th percentile, which means you scored higher than approximately 99.5% of the general population on a standardized intelligence test. This score falls into the Very Superior / Gifted range on the IQ scale. With a rarity of 1 in 185, this score is uncommon and indicates strong cognitive abilities.

Terman's original Genetic Studies of Genius (1925) and subsequent follow-ups showed that individuals at or above IQ 135-140 showed lifelong trajectories of exceptional intellectual productivity, professional distinction, and creative contribution across virtually all domains studied — from science and engineering to law, business, and the arts. SMPY longitudinal data extends and refines these findings across multiple modern cohorts.
