When the flag is displayed from a staff projecting from a window sill, balcony, or front of a building, the union should be at the staff's peak (unless the flag is to be displayed at half-staff.)

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 with another flag from crossed staffs, the National flag should be on its own right, with its staff in front of the staff of the other flag.

When flags of States, cities, or localities, or pennants of societies are flown on the same halyard with the flag of the United States, the latter should always be at the peak.

If displayed flat against the wall on a speaker's platform, the U.S. flag should be placed above and behind the speaker with the union of the flag in the upper left-hand corner as the audience faces the flag.

When displayed from a staff in a church, public auditorium or convention hall, the U.S. flag should hold the position of superior prominence; in advance of the audience and in the position of honor at the speaker's or clergyman's right as he faces the audience. Any other flag displayed should be placed on the left. The U.S. flag is always on the speaker's right whether it is placed on a platform or whether it is placed at floor level.

The flag, when carried in a procession with another flag or flags, should be either on the marching right; that is, the flag's own right, or, if there is a line of other flags, in front of the center of that line.

When the flag is used to cover a casket, it should be so placed that the union is at the head and over the left shoulder. The flag should not be lowered into the grave or allowed to touch the ground.
