Calibrating my screen (thinkpad X220, 12.5", 1366x768 (16:9)) with a spyder 3 express (I believe it was), the colored square was smaller than the device. Enlarging the square a little would make it easier to hit it. See attached photos.

That Spyder sure looks like a facehugger from Alien!

I'm affected by this issue too, as I'm trying to calibrate projectors with spectrometers; a small square won't do the trick in that case.

Methinks the color should not just be bigger, it should be fullscreen.

If someone wants to work on this, the relevant code is at https://git.gnome.org/browse/gnome-control-center/tree/panels/color/cc-color-calibrate.c#n1091 :

That is, the hardcoded
  gtk_widget_set_size_request (priv->sample_widget, 400, 400);

...in the cc_color_calibrate_init method.

hughsie mentioned: "I think we want it to be a little less than the entire screen to leave room for the progressbar and the buttons; cc_color_calibrate_set_kind is called IIRC, which should tell you what we're trying to measure [projector or other type of devices], in https://github.com/hughsie/colord/blob/master/lib/colord/cd-enum.h#L212 "
