It’s a very individual thing on tank size. Need to consider not only your goals, but budget and time as well which is hard until own a few tanks, not that you haven’t of course.

I found personally over the decades I like nanos. Previously I had a custom 6’ that I found too much work for me so limited myself to 4’ but even then I decided to upgrade to a 15g IM. I say upgrade because for me it was!

I do think 40b is the sweet spot unless fish only. I see a lot of people follow, which I think is some of the worst advise in the hobby, to go big as you can. Many of these people have a terrible experience with huge tanks and leave the hobby. I wonder if we would retain more people if they had instead done a 3’ or 4’ tank. But again it’s personal.

The length of the tank is often largely dictated by the physical space you have to fit the tank in, you don’t have this challenge from the picture, but I’d say no more than 10ft, as a good sweet spot.

The big decisions (IMO) is always the depth and the width.

Too deep and maintenance is a challenge.

Not wide enough for the depth, and it looks out of proportions.

As a rule, I always want the width greater than the depth.

My new tank is 7ft long (odd size but space constrained), by 4ft wide, by 2.5ft deep.

This is the maximum depth I’d want to go for this width, it’s difficult enough to touch the bottom at the edge. Coral placement is going to be “fun”.

I wish I could have gone longer though!!

I will have front and back access but my height is limited to 25 because of ceiling. I think 36” width won’t be a challenge. I’m pretty set on 9-10’ wide and if I increase width 40” will be MAX. but I think I’m asking for trouble over 36” wide. Honestly I think 10x3x25” is where I’m at… it is really good sqft and I think I can service it well

I know this will probably not help, but the most eye-pleasing aquariums I've seen dimension wise is where the length is 2.5 times the width.

Hence 144x60, 120x48, 96x40, 72x30, etc.

I would personally say that over 1k gallons or so can get into interesting challenges. You start to run into equipment availability issues as things are generally made for smaller tanks. You really have to be a very smart and resourceful person when setting up. Things like flow, lighting, filtration, can become tricky. Ive been to Dave Anderson's 5k tank and it took years of thought and planning to get it going. He also constantly had to adjust for new challenges.

A good Polo reef comment was something like. " it didnt matter if he had all the money in the world, it still took 6 years of planning"

Agreed; Polo Reef really didn't cut any corners when building his 17000G.

I highly recommend this video [regardless of what size you choose]:
