I've read countless reviews such as this one where reviewers, after carefully calibrating the tested monitor, are able to calculate how much of either sRGB or AdobeRGB the display is capable of cover, shown in a percentage value.

I know there are several ways to graphically see the difference (if there's any!) between a certain color space and the monitor's, but it seems I can't find anywhere a software which will tell me in percentage of much of sRGB/AdobeRGB/etc. my display is able to cover.

Does anyone know of a software which, given my monitor's calibrated ICC profile and a colorspace, will tell me in percentage how much my monitor covers?

  • I find the whole notion that one can describe how much of a display gamut is within sRGB or Adobe RGB as a percentage misleading. For one thing I've never seen a description of what the "percentage" is relative to. I presume it's the percentage of volume in CIE xyY space. But what about uvY space or CIELAB space which are better spaces for comparing color perception. These are all going to produce different percentages. – doug Mar 8 '20 at 15:39

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.

  • Strangely I don't get those parameters... do I have to make a new calibration using DisplayCAL to make them appear? – Luca Jun 14 '18 at 17:45
  • @Luca Hmmm — it may actually be info written into this specific profile. I'll investigate a bit. – mattdm Jun 14 '18 at 18:03
  • sorry to annoy you, but another thought crossed my mind: if those are parameters which have been set in the ICC profile by the calibrator, can you tell me which software you used to produce that ICC profile? – Luca Jun 16 '18 at 10:16

    Wait. 59.6% sRGB coverage? Seriously? That is actually worse than my $230 netbook, which measured at 61.2% (using a ColorMunki Display colorimeter). My netbook also happens to be made by Lenovo, and I kinda suspect this is not a coincidence... – bwDraco Sep 21 '18 at 5:04

    @xiota DisplayCAL has performed external measurements to come up with the profile displayed under Profile Information. – D. Jurcau Apr 26 '19 at 8:32

If you have a spyder 5 pro it will give you a chart and percentages of coverage for srgb, ntsc, and adobe rbg

Here is my srgb resultenter image description here

  • Most of the screen calibration tools, so called colorimeters, will show you this. so this cannot only done with the spyder (there is also a new one now) but also with for example X-Rite’s ColorMunki series which are a little bit cheaper. – LuZel Mar 5 '19 at 8:10

I suggest using BasICColor Display for software and an Xrite i1 DisplayPro for hardware.

After calibration and profiling the BasICColor Display will tell you your Delta E errors and your monitor's gamut size.


If you have a Mac you can use the Colorsync App that is included within the Utilites folder for it.

  • I can't seem to find a way to use it :( I only get the visual gamut, but cannot find any place where it says "your monitor profile covers xx% of sRGB or AdobeRGB" or whatever. Can you kindly post a step by step guide using Colorsync? – Luca Jun 14 '18 at 18:44
