That bottom diagram helped a lot...then i mis spoke and renamed the thread...not asking about Front Wides, but front Heights. My current front atmos are in the ceiling about 2-3 ft forward and 9ft up from my sofa. My rears are appx 18-24inches behind me and 9ft up as I have 9ft ceilings.
I guess if i were to do front heights, i would be 7.2.6, correct? Not sure it would be good for my room being i cannot move the ceiling speakers which would be in front of me instead of above me as Mids
You don't want Top Middle only. Many have stated the Top Front and Top Back is the gold standard for home Atmos.
So this is what your more ideal setup will be.

If you have the ability to add Top Middle to this as a 7.1.6 arrangement, you could, but many report lack of content depending on source and upmixer used in the Top Middle.
You can add Front Height if you want, but if you already have a working Top Front, it's value may not be as strong. The Height Speakers tend to be used for budget installs where in-ceiling Speakers aren't possible. Some report good effect, other disappointment. YMMV.
The other thing people do is mount the Top Front/Middle/Back Speakers on the side walls (similar to Height Speakers, and aimed at the LP.
This is how I will be installing mine, soon.
The most important aspect of getting good Atmos is the angles. Where the Speakers are relative to the listener is a big component of the experience. We all have to make allowances and compromises for our rooms, but the closer you can get to the proper placement, the better success you will have with the actual experience.
Finally, different AVRs will allow only specific placements. My Marantz SR6012 is like this. If you want to make certain what your AVR will allow, you should deep dive into the Amp Assign and Speaker placement tool in the settings. In my Marantz, I have to toggle it to full 11 channel on in order to play with it, but then you can see what placements and combinations the AVR will support.
For me, I am limited to .4 Atmos only and can do some combinations of Height and Top Speakers. Newer and more advanced machines can often do more and will vary by device.
