Seeking advice on new tank width (front to back depth) and height. Is 48" too wide?

[Seancj]

I'm planning a new tank and have been strongly considering a 48" width (front to back depth). The tank's overall all measurements will be either 72" x 48" x 20" or 60" x 48" x 20". I've actually even considered a 60"x 60" x 20". I will have access to 3 sides (one long and two short), so somewhat of a peninsula style tank.
It's going to be a Magnifica anemone specific reef with a shallow rock structure, and, hopefully, blanketed by beautiful anemones. Top-down viewing will also be a priority as I love the tidepool look.
Anyone with 48" wide tanks care to offer personal experiences? Any regrets going that wide for either viewing or maintenance reasons?
Will 20" height be enough height to properly view all the way back when looking through the front pane and truly enjoy the depth of aquascaping? How short is too short? Could I get away with 18" height?
Any advice and opinions welcome!
Thanks!
Oh, here is my current anemone reef that I hope to upgrade to a much large scale:

mine is 48 inches front to back and I love it, no regrets on a peninsula at 30 inches high with glass panels and barebottom, it's easy to maintain. I also put my tank pretty low so it looks nice from sitting on the sofa and gives me a good view of the bottom when viewing from the standing position. Equipment is in the basement.

My 660 dimension - 8.5ft x 49" deep and 35" high
Your challenge will be placement of rocks and cleaning back wall if desired. To stock that tank, I accomplished best with teenagers (see below).
If going 4ft deep, I recommend at least 60, preferably 72" long

Thanks for the replies!
Vetteguy- that's definitely fun way to get the family involved in aquascaping the tank! Love it!
P.S. I'm also a bit of a 'vette guy'! '69 small block

 

[Seancj]

Can anyone else offer opinions on the above dimensions?

You're way out of my league here but I like the idea of sticking to as short as possible (height) for maintenance if you can swing it,,, considering your aquascape plan.
*I switched from 22" high 37G to 16" high 40G just for that reason and am glad I did

My tank is 9’x4’x30”. The width really makes a big difference. True that it’s a bit more to clean but also true that your livestock will enjoy much more.

Go as wide as can!

What are your guy's thoughts on 18" to 20" height when viewing as far back as 48"?

My 200 is L72"xW24"xH27". The only regret is not having gone at least 6-12" more width front to back. Longer works for me but I don't think I would want deeper than 27" for ease of maintenance. Also don't think I would want more than W36" unless it was a peninsula. Would love one but not really any good place for one.
