Evilard lies 697 m above sea level, and one kilometer north of the district capital city, Biel/Bienne, as the crow flies. The town spans a southeast-facing clearing of the front of the Jura mountains, about 300 m over the city of Biel. In clear weather, the view from Evilard of the Swiss plateau and the Alps from Mont Blanc to the region of Glärnisch and Alpstein is quite impressive.
The municipal area of 3.7 km² reaches to the height of the anticline of Magglingerberg. It includes the town of Eviilard, which is surrounded by Malewagwald (French: Malvaux, up to 765 m altitude). To the southwest, the municipality reaches in a narrow stripe over the Magglingen to the peack of the Magglingerberg, up to the municipal high point of 1070 m. The towns comprise 29% of the area of the municipality (as of 1997), while 40% is forested, 30% is used for agriculture, and less than 1% is unproductive land.
In the municipality is also the town Magglingen (French: Macolin), which lies at 875 m on the southeast slope of Magglingerberg. The neighboring municipalities are Biel/Bienne, Orvin, Lamboing, and Tüscherz.
With 2312 inhabitants (at the end of 2004), Evilard is one of the largest municipalities in the Bernese Jura. In 2004, 60% of the population spoke German, and 40% spoke French. The population of Evilard underwent marked growth in the middle of the 20th century, whereas since 1980 only a small fluctuation has been registered. The migration of a number of settlers from the German-speaking portions of the Canton of Bern has increased the proportion of German speakers in Evilard, an area that was historically dominated by French speakers.
Evilard was dominated by agriculature until the beginning of the 20th century. Since about 1950, the town has built a large number of single-family homes for commuters working in Biel/Bienne. Magglingen has developed into a resort location starting in about 1875, thanks to its sunny high altitude. Today the town has many tourist facilities, and includes the Eidgenössische Hochschule für Sport Magglingen (Federal College of Physical Education in Magglingen, EHSM).
