It ccomes out from the wall where it's attached back 13.5 inches. The gate to walk thru is about 17 inches and the adjustment area can go out about 21 inches. I have it expanded to fill a spot I had a slider and it's open to 69 inches but I have another 5 I could add to it if needed. Hope this answers your questions, the gate is GORGEOUS!
