the riser is 16'' high. I wanted it 15.5, but it is what it is. I built a few steps 8'' tall, 24'' wide that i will carpet and keep mobile. The plan is to be able to move them around as my furniture changes in the room. I've ordered carpets for the main part of the room, and some engineered hardwood for the front stage. With the holiday week coming up, I doubt I'll get anything done, but a couple more days of work, and it will be complete. I'll tac up a few more pics when i get a chance.
