Although very damaged, the skull measures approximately 20 cm (200 mm), the arches and centra of the sacral vertebrae are not fused, which indicates that this specimen was not fully grown when it died, probably a juvenile individual.
Its size is estimated at 60 cm (2.0 ft) long with a weight between 2.27 to 9.1 kg (5.0 to 20.1 lb).
However, due to the immature nature of the specimen, the adult size is estimated around 2 m (6.6 ft), or similar to Protoceratops.
The frill has large fenestrae bounded by very slender struts.
This structure is very similar to that of the later Protoceratops.
Graciliceratops is recognised by the fragile frill and characteristic tibial-femoral ratio (1.2:1); the frill is also briefly elongated with well developed squamosal processes.
Seven sacral vertebrae were identified and not fused.
The scapula is very gracile in constitution but thicker at the glenoid, with a relatively large coracoid; the humerus is also very slender.
The femur measures 9.5 cm (95 mm), it is lightly curved and has a large head; the fourth trochanter is fragile and place above the midlength of the femoral end.
Being larger than the femur, the tibia measures 11 cm (110 mm) and its proximal articulation is more developed than distally.
The right pes is virtually complete, only lacking the distal end of the IV metatarsal.
The pedal unguals are dorsoventrally flattened and somewhat sharply-developed.
