We bought 4 of this for a trip to Europe. The size is exactly what we were looking for - a carry-on that is accepted by all airlines. We didn't have to measure it at all, it seems to be the right size for all airlines we flew on. The fabric inside is thin, but held pretty well during our trip. I love the colors and design. All in all, this is a great buy. A whole month all over Europe seems to not impact the bag. Let's see how long it lasts!
