# 固定標尺和十字準線
當您需要對齊畫布上的元素時，新的固定標尺和十字線可以幫助您更精確地測量和控制佈局。使用固定標尺，您可以隨時參考顯示在畫布底部的水平標尺：
為了獲得更精確的測量，可選的十字準線為您提供與固定標尺相交的動態垂直參考線。您可以沿著畫布拖曳十字線：
若要啟用標尺，請透過點選設計器頂部欄中各個裝置斷點旁的畫布大小（例如，1699 PX）來開啟**畫布設定**。從畫布設定中，選擇**標尺選項**。您也可以按下鍵盤上的**Shift + R來切換標尺。**
我們希望此更新可以幫助您更有效地測量和調整您的設計。查看[Webflow University 上的文檔](https://university.webflow.com/lesson/canvas-settings)，以了解有關固定標尺和十字準線以及其他 Canvas 設定的更多資訊。
