I have a large toddler (height + weight 95th percentile), he was wearing 18 month old clothes on his first birthday. Purchased size 18-21m, when he was about 14m they fit but were a little tight (his shoes were a size 5 at the time). And at 16 months he didn't fit in at all (shoe size 5.5-6). So I would say they are a bit small and these 18-21 month old boots are the equivalent of a size 5 Stride Rite. I think the reason is that they have a faux fur lining which should make them warmer but that also takes more space away. space in the trunk.
