How to adjust size of Google Map

Dear all,
where and how can i define the size of the map for eventlocation in Google Map. I would prefer to keep it variable.
over40

would say that the size of the map can be defined within googlemap.css or is that not what you meant?

did take a peak at your site and did see there were some template problems. The filter buttons are messed up and the edit form is probably also looking not nice.
--> it is something we are aware of and it will be addressed soon.
