EEG Cap Sizes

We provide caps in a range of sizes for human participants at any age.

Cap sizes reflect the participant's head circumference, measured at the hat line and expressed in even, two centimetre increments. They normally feature as the final 2 digits on our cap order codes (e.g. BC-64-UCMW-56).

Typical adult head sizes:

• 62
• 60
• 58 (average male)
• 56 (average female)
• 54

Children's head sizes approximately:

• 54 (11-14 years)
• 52 (5-10 years)
• 50 (3-4 years)

Infant head sizes approximately:

• 48 (2 years)
• 46
• 44 (7 months)
