The glossy shell of this snail ranges in height from 10 to 18 mm and a diameter of 14 to 22 mm. The number of whorls on the shell may be either 5 - 5 1/2 depending on locality. The shell is smooth and may have a uniform color that ranges from primrose yellow, olive-yellow, grey-yellow or grey-yellow brown with the lip being white in color. The shells may have one or five stripes that are chestnut-brown in color. There are also fine growth lines on the external surface of the shell.

Cepaea nemoralis and C. hortensis can be separated by the their distinctly colored apertural lip. In adult specimens of C. nemoralis the lip is always brown, while that of C. hortensis is white. Also C. nemoralis is larger than C. hortensis.
