How To Hang a Flag Vertically on a Wall or Building

Hanging the American flag vertically on a wall, window, or building facade is a popular display option for businesses, apartments, and homes without flagpoles. It is also one of the most frequently botched displays. The number one mistake is putting the stars in the wrong corner, which makes the flag look backward or, worse, creates the appearance of a distress signal.

The rules for vertical display are straightforward once you know them.

Why Vertical Flag Display Has Its Own Rules

When a flag hangs vertically, the orientation changes from what most people are used to seeing on a flagpole. On a pole, gravity and wind determine the flag's presentation. On a wall, you control the orientation, and the U.S. Flag Code specifies exactly how it should be positioned.

The core principle is that the union (the blue field with stars) must always be in the position of honor. For a vertical display, that position is the upper left corner as seen by the viewer. This applies whether the flag is indoors or outdoors, on a wall or in a window.

The Union Always Goes Upper Left

Section 7(i) of the U.S. Flag Code states: "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."

This means:

When the flag is hung horizontally (stripes running left to right), the stars go in the upper left corner from the viewer's perspective.

When the flag is hung vertically (stripes running up and down), the stars still go in the upper left corner from the viewer's perspective. The flag is essentially rotated 90 degrees clockwise from its horizontal orientation, with the blue field ending up at the top left.

If the flag is displayed in a window where it can be seen from outside, position the union in the upper left as viewed from the street, not from inside the room.

Horizontal vs. Vertical: What Changes

The star placement rule stays the same: upper left from the viewer. What changes is the direction of the stripes. On a horizontal display, the stripes run left to right. On a vertical display, the stripes run top to bottom. The flag is not flipped or mirrored; it is rotated.

The flag should lie flat against the surface. It should not bunch, sag, or fold over itself. If the flag is too large for the wall space, use a smaller flag rather than folding or tucking the excess.

How To Mount a Flag on a Wall

Grommets

Most outdoor flags have two brass grommets along the heading (the reinforced left edge). You can hang the flag from nails, hooks, or screws through the grommets. For a vertical display, the grommets end up along the top edge. Use additional fasteners along the bottom edge to keep the flag from curling or shifting.

Sleeve or Rod Pocket

Some flags have a pole sleeve (a fabric pocket along the heading) instead of grommets. Slide a dowel or curtain rod through the sleeve and mount the rod to the wall with brackets. This distributes the weight evenly and keeps the flag flat. For a vertical display, the sleeve runs across the top.

Adhesive and Temporary Options

For renters or temporary displays, removable adhesive hooks or strips (like Command strips) can hold a lightweight flag without damaging the wall. Use enough hooks to support the weight of the flag evenly. One hook in each corner plus one or two along the top edge prevents sagging.

Frame

Framing the flag behind glass is the most polished indoor option. The flag is stretched flat over a backing board and enclosed in a frame. This protects the flag from dust, handling, and UV damage while providing a clean, professional look. Make sure the frame uses UV-protective glass and acid-free backing to preserve the flag long-term.

Hanging on the Outside of a Building

When hanging the flag vertically on the outside of a building (from a balcony, facade, or window), the same rules apply: union in the upper left as viewed from the street. Use hardware that can handle wind. Outdoor wall-mounted flags need secure fasteners at all four corners, plus intermediate points along the top and bottom edges for larger flags.

Choose an outdoor-rated flag (nylon or polyester) for exterior wall displays. An indoor flag fabric will deteriorate quickly from UV and weather exposure. Colonial Flag carries outdoor flags in sizes suited for wall and building-mount displays.

If the flag is hung from a horizontal pole projecting from the building (an outrigger or bracket), the display rules shift to standard pole display: the flag hangs from the pole with the union at the top of the staff, away from the building. Check the flagpole components at Colonial Flag for bracket and outrigger options.

Common Vertical Display Mistakes

Putting the stars in the upper right corner instead of the upper left. This is the most common error and makes the flag appear backward.

Displaying the flag upside down. An upside-down flag is recognized internationally as a distress signal. Unless you are signaling an emergency, the union must always be at the top.

Letting the flag sag or wrinkle. A flag that bunches in the middle or droops at the corners looks sloppy. Use enough mounting points to keep the fabric taut and flat against the wall.

Displaying a worn or faded flag. A wall display puts the flag at eye level where every imperfection is visible. If the flag is faded, frayed, or stained, replace it. Colonial Flag offers a flag repair and rotation program to keep displays looking sharp.

Frequently Asked Questions

Can you hang a flag vertically with the stripes going horizontally?

No. When displayed vertically, the stripes should run top to bottom. The flag is rotated, not flipped. The union remains in the upper left corner from the viewer's perspective.

Does the same rule apply for flags in a window?

Yes. The union should be in the upper left corner as seen from outside the building (from the street or sidewalk), whether the flag is horizontal or vertical.

What size flag works best on a wall?

Measure the wall space and leave at least 6 to 12 inches of clearance on all sides. A 3x5 flag is the most common size for indoor wall displays. A 2x3 works for smaller spaces, and a 4x6 or 5x8 fills a larger wall or building facade.
