Make pixel size numbers in Preview show larger when editing photos? I occasionally have trouble seeing the small pixel-size values that Preview.app displays while editing photos. For images that are close to 640 pixels, I like to keep them just under 640 so they display full size in Stack Exchange, like the image below does in this question.

Is there any way I can ask Preview to just make those numbers a bit larger? Permanently is fine, or a hot key. I'd like to avoid solutions that just zoom the whole screen.
It's not possible to customize the size of the said on-screen numbers shown by Preview.app.

As a workaround and a more generalized solution for other such cases, you can leverage the Screen Zoom feature available in macOS. Although it's an accessibility feature, it is generally employed by UI designers to create pixel perfect UI.

To enable and configure Screen zoom, go to System Preferences app → Accessibility → Zoom, and enable the checkmark for Use scroll gesture with modifier keys to zoom. Now assign a convenient key to be used as modifier key (I use Control).



Once configured, you can press and hold the modifier key and scroll to quickly zoom in and out of your screen.
