Well, Rollo, I pulled mine out. Other banjos may have different dimensions. Mine is a cheap one. Center of the nut to center of the bridge is 673mm. Another 110 mm from the center of the bridge to the end of the tailpiece. And about 132 mm from the center of the nut to the farthest tuning pegs. The strings come a lot longer and need to be cut, so the actual string length shouldn't be too critical. But they are probably a little over a meter when they come out of the package. As for Banjo Bonnie, I'm guessing 95cm x 59 cm x 85 cm. Hope this helps, but remember, mine is a cheap instrument, not even a brand name on it. A better instrument may be more representative. BlueJay
