The community of Kleinostheim is about 40 kilometers east southeast of Frankfurt am Main about a half hour drive from it.

[3] Owing to the favourable transport connections over an important north-south railway link and the Autobahnen A 3 and A 45, and because it lies on the Rhine-Danube waterway and in the middle of the Frankfurt Rhine Main Region, the community offers many advantages as a location.

Kleinostheim benefits from lying near prosperous cities such as Frankfurt, Offenbach and Aschaffenburg by serving as a commuter town.

For almost a thousand years it was ecclesiastically and politically tightly bound with Saints Peter's and Alexander's Monastery in Aschaffenburg.

(as at municipal election held on 2 March 2008) The community's arms might be described thus: Gules a base wavy argent, above which an oaktree with five leaves Or between a wheel spoked of six and a spade blade in pale of the second.
