                                A 1-ounce (28g) single-serving bag of classic Lays chips contains approximately 160 calories. However, the total number of calories in a full bag of Lays depends entirely on the size of the bag and the specific flavor. Large family-sized bags can contain well over 1,000 calories, emphasizing the importance of checking the nutrition label and understanding serving sizes.
