Dick, Yes. Overall string tensions vary quite a lot depending on the size and type of piano. Two pianos of the same length, but of different brand -- designs -- may also vary quite a lot. In my archives I have measured scales -- for "modern" pianos -- ranging from approximately 34,000 pounds up to approximately 64,000 pounds (15,400 to 29,000 kg.). Most current production scales will fall into the range of approximately 35,000 to 45,000 pounds (16,000 to 20,00 kg.).
