File Font Size

Picture Window is dpi-aware which means that its fonts, icons and other interface elements are automatically adjusted in size to maintain readability regardless of pixel density. Thus on a newer monitor with very tightly packed pixels, fonts and icons are displayed in larger sizes to make them readable while on older monitors with low pixel density fonts and icons are displayed smaller so they fit on the screen. The ability to allow applications to adjust themselves in this manner was first introduced in Windows 10 -- earlier version of Windows support high-dpi monitors to varying degrees. The Font Size command lets you further fine tune font and icon sizes. Changes you make do not take effect until you close and re-open Picture Window.

This command lets you make text and icons larger or smaller and lets you select the interface font.

Menus and other parts of the standard Windows interface are not affected – to enlarge or reduce the Windows 10 interface (and everything else), right click on the desktop, select Display Settings, and adjust the the Scale and Layout percentage.

Picture Window uses this setting as a starting point to adjust its base font and icon size.
