How do I see the size of a brush in UE4?

I used to be able to build levels back in the old days 1999- 2001. When I created a BSP brush I could set in to be a box and create it 128 units high. I could apply a texture to that and it would be the about size of a one story building. Now when I create a brush I have no idea how big it is and how the texture will apply.

Where can I get the actual units in the editor. I just see scale values.

When you click your brush, on the right hand side you should see something saying brush settings under details. You may have to hit a small arrow if it’s not there. The x y and z change your brush size. Let me know if you can’t find it still.
