Background: Dimensional data are crucial for developing normative standards based on sex, and age. Objectives: In this study, the size of the corpus callosum and the longitudinal as well as vertical dimension of the brain was measured using an MRI in healthy individuals, and the corpus callosum's size in relation to a person's age & gender. Patient and methods: 100 healthy volunteers (44 men and 56 women) admitted to the Teerthanker Mahaveer Hospital, Moradabad, U.P, had their corpus callosum size on the midsagittal section measured by magnetic resonance imaging (MRI).The Corpus Callosum's lengthwise & horizontal measurements, the brain's lengthwise & horizontal dimensions, and others dimensions were also recorded. These dimensional parameters were compared by using independent sample "t" test, ANOVA test, tukey test, & Pearson correlation. Results: Between males and females, there was a difference (p<0.05) in the frontal to occipital lobe (AB) in the age group of 21-30, the frontal pole to the genu (AE) in the age group of 51-60, the occipital pole to the splenium (BZ), and the brain's upper to lower border (CD) among the ages of 51-60. Frontal pole to genu (AE), Length of CC anterior up to distant end (EZ/3), CC's front to posterior-most end distance (EZ/5), & Length of CC (EZ) according to age groups were different (p <0.05).
