How can I measure my monitor’s sRGB and Adobe RGB coverage percentage?

After calibrating and profiling a monitor, how can I find the percentage of a standard color space—such as sRGB or Adobe RGB—that the display can reproduce? I’m looking for software that can use the monitor’s ICC profile (or a fresh calibration/profile) and report gamut coverage as a percentage, rather than only showing a graphical gamut plot.

The tool displaycal-profile-info, part of the DisplayCAL package, can do this. This works (and works basically the same way) for Windows, Mac, and Linux.
See for example for my (calibrated) ThinkPad screen:
... which has a 60% coverage of sRGB and 43% coverage of Adobe RGB.

Yes—this is typically reported by display calibration/profiling software rather than by the ICC profile alone.
A commonly recommended option is DisplayCAL: its displaycal-profile-info tool can show gamut coverage figures such as the percentage of sRGB and Adobe RGB covered by your calibrated display profile.
Other calibration packages can also report this after profiling. For example:
- Spyder 5 Pro can provide charts and coverage percentages for sRGB, NTSC, and Adobe RGB.
- BasICColor Display (used with hardware such as an X-Rite i1 Display Pro) can report gamut size and calibration accuracy metrics like Delta E.
In practice, the usual workflow is:
- Calibrate/profile the monitor with a colorimeter.
- Open the profile analysis/report tool in the calibration software.
- Read the reported gamut coverage percentages for the target color spaces.
So if you want a direct answer to your question: DisplayCAL is a good cross-platform solution for checking your monitor’s sRGB/Adobe RGB coverage percentage from a calibrated profile.
