The dimensions of the rover can be found in a Jet Propulsion Laboratory

On page 4, the description reads:
The rover has a mobile mass of 11.5 kilograms.  On its top is a flat solar
panel a quarter of a square meter in size that will provide 16 watt-hours of
peak power.  The rover also has a primary battery that will provide 150
watt-hours of power.  The rover has a normal height of 280 millimeters with
a ground clearance of 130 millimeters.  It is 630 millimeters long and 480
millimeters wide.  Its six wheels are on a rocker-bogie suspension system
that permits the rover to crawl over small rocks.
