E.g. for walls and arches made of firebrick sizes: 230x114x64mm (9"x4.5"x2.5" OR 8.5"x4"x2.5")

Option 1: stack three bricks on their side and create an arch with 16 bricks to come up with a total height in the vault at 420mm - 16½"

Option 2: stand the bricks on their side and create an arch with 15 bricks and come up with a total height in the vault of 413mm - 16¼"

You can get the true 407mm - 16" with any size fire bricks exactly (also with splits 51mm - 2" thin) by adding one more bricks to the arch and push both arch-sides (not walls) sideways a bit lowering the center down, 8-3/4" x 4-1/4" x 2-3/8" too. The 12.5mm - 1/2" will not make difference in chamber height but make entry 254mm - 10".

I kind of like option 1, it has more of a nice arch to it. But both are perfect for heating.
