Fabric, elasticity

Our caps are made with two different fabric elasticities.

The medium elasticity or 'High Precision' fabric provides a precise reproduction of electrode positions, across and within subject recordings, a longer life span for general wear and tear, and a quick drying time.

The high elasticity or 'High Comfort' fabric provides an optimal fit for a larger variety of head shapes, and due to its softness is great for children or participants with a sensitive scalp.

On our webshop we sell caps according to our standard recommendation, which depends on the size of the cap: 

  • 52 cm and above are manufactured with High Precision fabric;
  • 50 cm and below are manufactured with High Comfort fabric.



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)
  • 42
  • 40 (3 months)
  • 38
  • 36 (newborn)


In contrast to other EEG cap manufacturers, Easycap uniquely offers two standard cap cuts.

  • C-Cut: designed for oval head shapes. It is the first choice of laboratories located in America, Europe and India.
  • A-Cut: designed for round head shapes. It is favoured by laboratories located in China, Japan and Korea or by any other lab with participants with North- and East Asian heritage.

Example order codes are CACS-SCMW-56 for C-Cut, and CACS-SAMW-for A-Cut.

This option comes at no extra cost, simply add the desired variant into your basket.
