Oh thanks for your reply. But I think you have sent me the measurement for string spacing (the outside of the top E to the outside of the bottom E). The action is the height of the strings above the fretboard (measured from the top of the fret to the bottom of the string). It's usually about 2 mm.

お返事ありがとうございます。送っていただいたのが弦の間隔の採寸（１弦の外側から６弦の外側まで）だと思うのですが、計っていただきたいのが指板の上にある弦の高さ（指板の上部から弦の底部まで）です。2ミリが一般的です。
