Basic Display Rules
The Union Jack has a correct and incorrect way to be displayed. The flag should be positioned so that the wider white diagonal stripe appears on top at the hoist side, which is the left side when you are facing the flag. This is the most important rule for proper display. If you hang the flag upside down or backwards, it will look noticeably different because of the asymmetrical design of the crosses.
Horizontal and Vertical Display
The Union Jack can be displayed either horizontally (the most common way) or vertically. When hanging vertically on a flagpole or wall, the same rule applies: the wider white diagonal stripe must be on top at the hoist side. Whether horizontal or vertical, the flag should never be allowed to drag on the ground or water, and it should be raised briskly and lowered slowly as a sign of respect.
What the Flag Represents
The Union Jack combines three crosses representing the three countries of the United Kingdom. The red cross of St. George represents England, the white diagonal cross of St. Andrew represents Scotland, and the red diagonal cross of St. Patrick represents Northern Ireland. Wales is not represented by a separate cross on the flag. Understanding these components helps explain why the flag has an asymmetrical design that requires proper orientation.
Official Settings and Protocols
The Union Jack is displayed at government buildings, courthouses, military installations, and during official state ceremonies. In formal settings, the flag should be treated with respect and never used as a decoration to cover tables or other surfaces. When displayed alongside other flags, the Union Jack should be given equal prominence and positioned according to diplomatic flag display protocols.
