Although it is a very nice belt esthetically, it is not leather. The belt is stamped as synthetic leather. There are no size indication on the advertisement but I took a few seconds to measure it. The belt is approximately 41 inches long from the tip of the buckle to the end of the belt. It is approximately 1 inch wide. My seven year old has a 27 inch waist and I need to make a few holes to fit him correctly. I could have purchased a large size but I'd rather make a few holes than need a few. Hope this brief description helps.
