In British English, chips are thick-cut fried potato slices, the kind served at a pub or fish and chip shop, while fries is short for French fries, the thinner, crisper strips more familiar from American-style fast food. A simple memory hook: chips are chunky, fries are thin.
The core difference
Chips and fries both describe fried potato strips, but chips are typically the thicker British style and fries the thinner style short for French fries.
- chips — fried potato slices (also broken pieces or gambling tokens more generally): We shared a plate of chips at the pub.
- fries — strips of potato deep-fried until crisp, short for French fries: She ordered a burger with a side of fries.
How to tell them apart
The two words describe the same basic food, fried potato, but the cut usually differs. British chips are thick and soft in the middle, the classic accompaniment to fish and chips. Fries are the thinner, crisper strips more associated with American-style fast food, and the word is simply a shortened form of French fries.
Chips also has meanings that have nothing to do with potatoes at all, such as tokens used in gambling or small broken pieces of something, senses fries does not share.
