Horizontal dials
Generally speaking, two sizes of horizontal dials exist: large and small. That sounds rather trivial, but in this case it's true: the 'large' ones are at least ten times larger than the 'small' ones. The large ones may be found in city squares and other public places.
Small horizontal dials are mainly set on a pedestal in private gardens, especially in the UK and the USA. In the following I call them garden dials. I know of only two in-between cases; I'll call them table dials.
Large horizontal dials are not very suitable for private gardens, given the necessary space and the maintenance they require.
Small horizontal dials can often be found in gardening centers and gift shops.
One sometimes wonders: is this supposed to be a horizontal or a vertical dial? If you are good at estimating angles, you can try and see whether the angle between dial face and gnomon fits the local latitude (for a horizontal dial) or its complement (vertical dial). This doesn't help around 45° latitude, of course.
Alternatively, you may check the scale: when the gnomon is pointing at you, the hour marks run counterclockwise on a horizontal dial and clockwise on a vertical dial. (On the southern hemisphere it's the other way round.)
Finally, a vertical dial shows 12 hours at the most, while a horizontal dial for the temperate zone may show several hours more. A dial for the Netherlands, for instance, may show about 16 hours.
