The two pictures at right show the SX110 in comparison to the Canon SD850, which is a true pocket sized camera (though slightly more bulky than the average 'compact' camera, these days). On the off chance that you don't have personal experience with the SD850, I've also included an Altoids can, which is about the same size.
The SX110 measures 4.35 x 2.77 x 1.76 in., which, BTW, is bigger than the SD850 in every dimension. It's also a little bit heavier than the SD850, but not as much as you might expect. The upside of the camera's size, however, is that it's a very comfortable camera to hold, unlike the SD850, where there is little to get a good grip on. In fact, the right side of the SX110 has a beveled edge, which serves as an excellent grip.
When turned on the lens extends, nearly doubling the length of the camera. When the lens extends, the camera gets quite front-heavy, and will tip forward unless balanced on a perfectly flat surface. This may make it more difficult to take action shots of yourself using the 10 second self timer, unless you use a tripod.
