I don't think there is a formula for brick usage. Only general guidelines since virtually every oven is cut differently. SketchUp (free) is a useful software tool in mocking up your oven down to the last brick and will give you exact dimensions of everything.

Take half the volume of the interior sphere from half the volume of the exterior sphere and this will give you the volume of the brick oven wall. Next you'll need to take out the entry to the dome, add back the brickwork in the entry and the floor. I think I used somewhere around 280 bricks and I know I calculated the amount and put it in a thread.. I'll add the link when I find it.. Ah, here you are..

I don't know how much this thread answers you question but it should give you a way to estimate about what you'll need. Post 12 shows my math.

-What ever you think you will need, you will end up using more anyway. Just get started, that's what I say.
-What do you need that big of an oven for anyway. 54 " is a sh*t load of space. If your mostly making pizzas, they cook so fast you don't need a huge oven. It's hard for even the most experienced cooks to have more than 3 pizzas in the oven at a time (and build more pizzas). If your baking bread, I could see how it would be nice, but that's sill a lot of bread.

That's how I did mine. I bought a car load of bricks to get started then I was able to make estimates as I went along.

You're talking about a big oven. Commercial use perhaps?

That will be a nice size oven. Because it'll be in a restaurant setting, heating up that much mass won't be to much of an issue. It'll be hot all the time.

Off the top of my head the door height to dome height is 63%...someone chime in here. Don't think your oven too large..you will be glad when you have a little extra room for getting wood in, ash piles, etc while still baking pizzas with room to get away or closer to flames or find the sweet spot in the floor.
