ETSI has standardized a new form factor (4FF) for the SIM card, 40% smaller than the current smallest design.

The SIM is the most successful smart card application ever. A SIM card is used to securely associate a mobile device with a customer account, preventing fraud and ensuring that calls are correctly routed to customers. It is an essential security feature of mobile networks, and is integrated into every GSM, UMTS and LTE device. Over 25 billion SIM card and derivatives have been produced so far, and the industry continues to issue over 4.5 billion SIM cards each year.

From the ETSI Press release:

The new form factor was adopted by industry with the involvement of major mobile network operators, smart card suppliers and mobile device manufacturers. The new design will be published in due course in ETSI’s TS 102 221 specification, freely available like all ETSI standards from the ETSI website.

The 3GPP Specification 3GPP TS 31.101 defines the "UICC-terminal interface; Physical and logical characteristics" for the mobile system.

Today’s SIM card designs take up a significant amount of space inside a mobile device. This space is more and more valuable in today's handsets which deliver an ever increasing number of features.

The fourth form factor (4FF) card will be 40% smaller than the current smallest SIM card design, at 12.3mm wide by 8.8mm high, and 0.67mm thick. It can be packaged and distributed in a way that is backwards compatible with existing SIM card designs. The new design will offer the same functionality as all current SIM cards.
