The original Ikea cabinets from way back were not standard American sized. I remember a bunch of years back putting in a set for a buddy of mine, and we had a hard time with matching them up to his appliances. The newer ones were retooled to our standard cabinet sizing. So if wanted, you can match them up to existing kitchen cabinets.
Im still in the process of doing my kitchen. The wife changed the configuration around about six times already.
