Hi @AK1937, welcome to the Sonos Community!
Apologies for the delay in getting back to you. As this is something we don’t have measurements for, I have raised this my colleagues to see if any of them have the Era 300 floor stands, however none that replied so far do.
If you have any retailers nearby that stock Sonos and Sonos accessories, it may be worth checking if they have a display model and can check the measurements for you. Otherwise, my reply will put this thread to the recently active section where another community user who may have this setup can check for you.
If I do hear anything, then I’ll reply here with the measurements.
Thanks for your help Jamie - much appreciated!
Had to find a tape measure to pull out to do this. Not easily found.
1 ¾ inch from the back of the stand/platform to the pole. A further 1 ¾ inch from the pole to the back of the speaker.

Superstar - thanks so much for your efforts - much appreciated Bruce!
