|I think it is the inner diameter of the frame's headtube, but if you have a Dura-Ace headset, it's a 1 inch. That's all they ever made them in.

|The 1" or 1-1/8" dimension is the outside diameter of the steering tube.
A threaded road bike headset would certainly be a 1 inch.

|At least on quill stems, what everybody calls "one inch" actually measures 22.2mm in diameter (an inch is 25.4). That's what you're measuring at 7/8 inch, I imagine.
I have no idea why we call it one-inch.

|The outside diameter of all threaded steering tubes on road bikes is 1 inch.
The ID of the steering tube is 7/8 inch or 22.2mm.

|Buy a 1" stem, if it is too small, you have a 1.125 stearer NM||Marketing Dept|
