Your brain is about the size of two clenched fists

Hold two fists together and you have a rough everyday model of adult brain volume — packed with folds so the cortex fits that modest shell.

Size alone does not rank intelligence across people; organization and experience matter more than a centimeter of circumference.

Scale is humble. The organ that writes symphonies and spacecraft specs still fits in a hat.
