Does your logo or photo look squashed when in Google Maps? That’s because Google is just resizing the whole image in the search to 85w×60h. When you open the profile, the correct dimensions will display at,  220 wide, and some height.

When editing your image for Google Places (where you can change the Google Maps profile for your business), make the dimensions 680×480, and the image will scale appropriately in the map search, and look clean on the profile.
