Three card heights are allowed with VME; 3U, 6U, or 9U; a single slot card is 6T wide. Length is either 160mm or 340mm (Norm). The other possible lengths are: 100/160/220/280/340/400mm
Height is given in 'U', Length is given in 'mm', Width is given in 'T'; Most card sizes listed are one slot or 6T wide.

A size PWB = 3U x 160mm,
B size PWB = 6U x 160mm,
C size PWB = 6U x 340mm,
D size PWB = 9U x 340mm ... H x L x W {@ width=6T}

A, B, C, and D are VXI terms. VME normally only references 3U or 6U by a length.
VMEbus Extender cards come in any one of the board sizes listed above. Extender boards are used to extend the card under test out the front of the VME chassis [so it may be worked on]. The extender card will provide male connectors on one end of the card [to plug into the chassis backplane] and female connectors on the other end of the card [to allow the test card to plug in]. A VMEbus card extender may be either passive or active. A passive board extender simply runs the VMEbus signal from the backplane to the card under test. In some cases passive board extenders also provide jumpers or shunts to by-pass signals. Active extender boards provide signal buffering between the card under test and the VME bus backplane.
