When displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag's own right, that is, to the observer's left. When displayed in a window it should be displayed in the same way, that is with the union or blue field to the left of the observer in the street.

When hanging a flag vertically What side do the stars go on?

When hanging the Flag against a wall, vertically or horizontally, the Flag's union (stars) should be at the top, to the Flag's own right and the observer's left.

Is it disrespectful to hang a flag facing down?

There's a right and a wrong way to hang the flag vertically.

Don't hang your flag backwards, upside down, or in another inappropriate fashion. If you're hanging your flag vertically (like from a window or against a wall), the Union portion with the stars should go on the observer's left.
