I haven't really checked the dimensions. But I thought the sleeping bags were pretty standard. I bought it for my 2.5 years. It's good that he's a little kid because I'm sure he'll outgrow it quickly. This is a very small sleeping bag. It is very flexible inside and out. If I had a choice, I probably wouldn't buy it again. We will use it, but we definitely won't be able to use it outside in freezing temperatures or for more than a year or two. If it takes that long I'm not complaining about the price, hence 2 stars. This will get the job done. But definitely very disappointed.
