There are obviously good native ways of measuring distances in Figma and they work well in most cases. But there are however cases where the Figma way does not get you what you want. In those cases, here is a hack for mac users.
- Zoom into 100% in Figma
- "CMD + Shift + 4" to get the screenshot tool.
- The screenshot tool shows you the PX values that you need in the bottom right corner of the frame.
- "Esc" to cancel the screenshot when you have what you need.
When I am building a web application or site, this is usually good enough!
