Lots of variations, but usually between 330mm and 750mm.
Story
This was purchased while just doing a basic lookup of “thai instruments” on Ebay. A girl was just trying to make up some money to buy a new car because she was in a recent accident. Strangely, she was selling the subu at an extremely low price. After examining her description, I assume the low price was due to the fact that she did not know the identity of the instrument, just the fact that it was from Thailand.
