Izegem itself lies on the southern banks of the Mandel, Emelgem and Kachtem on the north.

Along the shores of the canal a large industrial zone has developed, which made the three municipalities one urban area.

The total area is 25.48 km2 (9.84 sq mi) which gives a population density of 1,042 inhabitants per km².

Today there are only a few factories left, but the city houses a shoe- and brush museum.

Until the 1920s, Izegem was often spelled Iseghem, which can be found on old passport applications,[2] birth records, and gazetteers.
