One way to hold this word is a dial marked scale, and someone turning it up. Turn it up on a piece of work and more of everything pours in: more people, more money, more hours, more ground covered. Turn it up on a drawing and the paper stretches, so what was a dot becomes a street with a name on it. Either way the word is not describing how big one object is — it is describing how far the dial has been turned.

可以想成有一個標著 scale 的旋鈕，被人往上轉。轉在一件事情上，進去的東西就跟著變多：更多人、更多錢、更多時間、更廣的範圍。轉在一張圖上，紙面像被拉開，本來一個小點的地方，變成一條標了名字的街。兩邊都不是在說某個東西本身多大，而是在說那個旋鈕被轉到多高。From the word’s history
Wiktionary gives the formation plainly: large + scale. The word is simply the size word put on the scale word, which is why both senses are about the setting of the scale rather than the size of an object.
Wiktionary 記載這個字的組成就是 large 加 scale。也就是把「大」直接掛在「刻度、比例」上面。這正好解釋了兩個意思的共同點：它們講的都是刻度被調到哪裡，而不是某個物件本身的大小。
