Thomson's gazelles are 50 to 70 cm (20 to 28 in) tall and weigh 15 to 25 kg (33 to 55 lb) (females), 20 to 30 kg (44 to 66 lb) (males). They have light brown coats with white underparts and distinctive black stripes on the sides. Their horns are long and pointed with slight curvature.

savannas and grassland habitats, particularly the Serengeti region of Kenya and Tanzania. It has narrow habitat preferences being confined to short grassland with dry firm footing. It does, however, move into tall grassland and dense woodland during migration
