The size 24 months is clothing designed for babies ages 18-24 months. The age range in the sizing for baby clothes refers to the oldest age the outfit is designed for. When a child reaches 18 months, they’ll usually be in the next size up, 24 months. The height range for 24 months is typically 32-34 inches, and the weight range is around 28-30 pounds. However, different brands may have different measurements for 24 months and 2T clothes, so it is always important to check the size chart. While 24 months and 2T are often thought of as the same, there are differences between the two sizes. Size 24 months includes features specially designed for babies, such as extra room in the diaper area and snaps at the legs, while 2T clothes are cut more closely in the diaper area and have a slimmer silhouette. Additionally, 2T clothes usually feature straighter lines than 24-month clothes or joggers, giving them a distinct “big kid” style.
