What Is the Grand Union Flag, and Which Name Are You Actually Buying?
The grand union flag is one flag with five common names. Every listing you find, Continental Colors, Cambridge Flag, Continental Union Flag, Congress Colors, First Navy Ensign, describes the exact same design: 13 alternating red-and-white stripes representing the united colonies, with the British Union Flag (the combined crosses of St. George and St. Andrew) in the upper-left canton. If a product listing uses any of those names, you are buying the same flag. The confusion ends there.
The design was in active use from late 1775 until June 14, 1777, when the Flag Act officially replaced it with the 13-star Stars and Stripes. Its first documented appearance was December 3, 1775, hoisted aboard the USS Alfred at Philadelphia at the commissioning of Admiral Esek Hopkins' Continental Navy fleet, which is why "First Navy Ensign" is one of its oldest and most accurate nicknames. It is also traditionally associated with Prospect Hill in Somerville, Massachusetts, near Washington's Cambridge headquarters, raised there on January 1, 1776, hence "Cambridge Flag."
The names "Grand Union" and "Great Union" are 19th-century labels, first widely popularized by naval historian George Henry Preble in his 1872 History of the American Flag. The colonists themselves used "Continental Colors" and "Congress Colors." When you shop for this flag today, any of those search terms will find you the same product, so use whichever your preferred retailer lists.
What Does the Grand Union Flag Actually Look Like?
The flag combines two visual elements from different political traditions. The stripes are original: 13 alternating red and white horizontal bands, one per colony. The canton is borrowed: the British Union Flag as it existed before 1801 (before the cross of St. Patrick was added when Ireland joined the union). This pre-1801 Union Jack shows only the red cross of St. George on a white ground, overlaid by the diagonal white cross of St. Andrew on blue.
The retained British canton was not an oversight. In late 1775 the colonists had not yet declared independence; the stripes asserted united colonial identity while the Union Jack signaled continued, if strained, connection to the constitutional crown. By July 4, 1776, the flag was flying over a newly independent nation with no canton redesign yet authorized. That redesign came with the Flag Act of June 14, 1777, producing the Betsy Ross–style 13-star circle canton. Flying the grand union flag today tells that precise in-between story: the moment America was becoming itself.
One popular claim holds that the flag was inspired by the East India Company's striped ensign. Vexillological researchers note that no primary source documents this as an actual influence, and the EIC stripe count varied from 9 to 15 depending on the era, so treat that story as an interesting footnote, not established history.
Grand Union Flag vs. Betsy Ross Flag vs. the Official 2026 Flag: Which Revolutionary Flag Should You Fly?
If you are planning a display for America's 250th anniversary on July 4, 2026, you have three strong historical options. Here is how they differ so you can pick the right one, or combine them.
| Flag | Era | Canton Design | Best For |
|---|---|---|---|
| Grand Union (Continental Colors) | Dec 1775 – Jun 1777 | British Union Jack | The "first flag" bookend; the transition from colony to nation |
| Betsy Ross (13-star circle) | Jun 1777 onward | 13-star circle on blue | The first official Stars and Stripes; birth of the flag we know |
| Official America 250 Flag | 2026 commemorative | 50-star field with "250" emblem | The present-day Semiquincentennial celebration marker |
The most powerful display for 2026 uses the grand union flag as the historical anchor, the first flag, 1775, alongside the current 50-star flag or the official America 250 commemorative, representing 2026. That pairing tells the full 250-year arc in two flags. For a deeper look at the 13-star options that came after the Grand Union, see our guide to the Betsy Ross, Cowpens, Bennington, and Hopkinson flags for America's 250th. You can find both the Grand Union and Semiquincentennial options in the 250th Anniversary Hats & Flags collection.
What Size Grand Union Flag Do You Need?
Match your flag size to your flagpole length. Flying a flag that is too large strains the hardware and causes premature fraying; one that is too small looks undersized and reads poorly from the street. Use this standard size-to-pole chart:
| Pole Length | Recommended Flag Size | Typical Setting |
|---|---|---|
| 5–6 ft (house-mount) | 2.5 x 4 ft or 3 x 5 ft | Porch bracket, wall bracket, EZ-mount rings |
| 20 ft in-ground | 3 x 5 ft | Residential front yard |
| 25 ft in-ground | 4 x 6 ft | Residential or light commercial |
| 30 ft in-ground | 5 x 8 ft | Commercial property, school, civic building |
| 35–40 ft in-ground | 6 x 10 ft | Large commercial or municipal display |
The most popular residential choice for the grand union flag is 3 x 5 ft, it fits a 20-foot in-ground pole or a standard 6-foot house-mount bracket equally well. For a porch or garage-wall bracket with a 5-foot pole, the 5-Section 5FT Stainless Steel Flagpole Kit pairs neatly with a 2.5 x 4 ft or 3 x 5 ft flag. For a yard-mounted pole, the 5-Section 6FT Stainless Steel Flagpole Kit handles a 3 x 5 ft flag with room to fly freely.
What Construction Should You Look for in a Grand Union Flag?
Because the grand union flag predates the star-embroidery era of flag-making, reproductions are printed rather than sewn with individual embroidered stars. That is the historically appropriate construction method for this flag, and it produces a lighter, faster-drying product. Here is what the construction specs on a quality reproduction should say:
- 200-denier nylon fabric: The industry standard for outdoor flags. Nylon flies in light breezes, dries quickly after rain, and resists UV fading better than polyester at comparable price points. For a deeper comparison of denier ratings and fabric weights, see our Flag Denier guide on 200D nylon vs. spun polyester.
- Digitally printed single-reverse design: The artwork is visible on one face; the reverse shows a mirror image through the fabric. This is standard for all-weather historical flags and is fine for outdoor display.
- Canvas header with brass grommets: A heavy poly-cotton canvas header adds strength at the hoist; solid brass grommets resist corrosion. Avoid zinc-alloy grommets that can seize on stainless snap hooks.
- Four rows of lock-stitching on the fly end: The fly end takes the most stress in wind. Four rows of reinforced stitching is the marker of a commercial-grade flag and significantly reduces fraying.
- UV-resistant ink treatment: Digitally printed flags must have UV-treated inks or the red and blue will fade within one season of direct sun.
Polyester is a valid alternative for very windy or coastal sites, it is heavier and more abrasion-resistant, but nylon is the better choice for most residential settings because it flies more gracefully in light wind and shows the stripes cleanly.

How to Display the Grand Union Flag Correctly
The grand union flag is a historical reproduction, not the current U.S. national flag, so the U.S. Flag Code does not technically govern its display. That said, the following conventions are widely observed and reflect respectful practice:
- On an in-ground pole alone: Fly it at full staff. Because it is a historical flag (not the current national flag), there is no half-staff obligation for national mourning periods, though many displayers follow the same schedule out of respect.
- On an in-ground pole with the current U.S. flag: The 50-star flag takes the position of honor, the peak of the tallest pole, or on its own pole to the observer's left if poles are equal height. The grand union flag flies on a secondary pole at the same or lower height, never above the current national flag. For sizing two flags on adjacent poles, see our guide to sizing a second flag for a flagpole.
- On a house-mount bracket: The canton (Union Jack corner) goes to the peak of the staff, the same orientation as the star canton on the 50-star flag. Use a bracket-and-ring system like the Premium American Flag Display Set so the flag can rotate freely and avoid wrapping.
- Indoor display: Place the canton to the observer's left (the flag's own right), matching standard indoor flag placement.
A common question: is it disrespectful to fly a flag with the Union Jack in 2026? The answer is no. The canton represents the historical moment, it is a period-accurate reproduction, not an expression of British allegiance. Displaying it with a period sign or label explaining its 1775–1777 context turns a historical artifact into an educational moment, especially during America's 250th anniversary celebrations.
To keep the flag flying cleanly on a house-mount pole, use Aluminum Alloy Bearing Rings, they allow the flag to rotate with the wind rather than wrap around the pole, which is the single biggest cause of premature wear on historical reproduction flags.
The 1775–2026 Semiquincentennial Display: How to Use the Grand Union Flag as the "First Flag" Bookend
America's 250th anniversary on July 4, 2026 is the strongest contextual reason to buy a grand union flag right now. The display concept is simple and historically precise: fly the Continental Colors as the starting point of the American flag story (1775), alongside the current 50-star flag or the official Semiquincentennial flag as the endpoint (2026). No competitor or history page is framing the purchase this way, but the storytelling logic is airtight.
For a two-pole yard display, position the grand union flag on the secondary pole to the right (observer's perspective) with a small placard: "Continental Colors, 1775, America's First Flag." The 50-star flag goes on the primary pole at the same or greater height. For a porch bracket with a single pole, rotate flags on significant dates: fly the grand union flag on Flag Day (June 14, the anniversary of the Flag Act that retired it in 1777) and the current flag on July 4.
Common Mistakes to Avoid
- Buying by nickname without confirming the design. "Cambridge Flag" and "First Navy Ensign" both describe the grand union flag, but confirm the listing shows 13 stripes and a Union Jack canton, not a 13-star canton, which is the Betsy Ross flag.
- Flying a 3 x 5 ft flag on a 30-foot pole. A 3 x 5 flag looks like a postage stamp on a 30-foot pole. Size up to 5 x 8 ft for any pole 30 feet or taller.
- Choosing polyester for a calm, inland setting. Polyester is heavier and will hang limp in light breezes. Nylon is the right material for most residential settings.
- Positioning the canton at the bottom of a house-mount pole. The canton always goes at the peak, highest point of the staff, regardless of whether it contains stars or a Union Jack.
- Flying the grand union flag above the current U.S. flag. Historical flags never take precedence over the current national flag in a multi-flag display.
- Leaving a digitally printed flag out in sustained high winds. Four-row fly-end stitching helps, but no printed flag is rated for storm conditions. Bring it in when winds exceed 30 mph, especially for a historical piece you want to preserve.
- Assuming the East India Company connection is documented fact. It is a popular theory with no confirmed primary-source evidence. Present it as lore, not history, if you use it for educational displays.
Frequently Asked Questions
Is the grand union flag the same as the Continental Colors flag?
Yes, completely. Grand Union, Continental Colors, Continental Union Flag, Cambridge Flag, Congress Colors, and First Navy Ensign are all names for the identical design: 13 red-and-white stripes with the British Union Jack in the canton. The various names emerged at different times and in different contexts, but every flag manufacturer using any of those terms is selling the same product.
What is the difference between the grand union flag and the Betsy Ross flag?
The canton is the only structural difference. The grand union flag has the British Union Jack (crossed red and diagonal white stripes on blue) in the canton. The Betsy Ross flag has 13 five-pointed stars arranged in a circle on a blue canton. Both flags have 13 red-and-white stripes. The grand union flag came first (1775–1777); the Betsy Ross style replaced it after the Flag Act of June 14, 1777.
Is it legal and respectful to fly the grand union flag today?
Yes. It is a historical reproduction flag, not a foreign national flag, and there is no law or code section that restricts its display. The Union Jack in the canton is a period-accurate historical element. Displaying it with a note about its 1775–1777 context adds educational value, particularly during the America 250 Semiquincentennial commemorations in 2026.
What size grand union flag should I buy for a standard house-mount bracket?
A 3 x 5 ft flag is the right size for most 5-to-6-foot house-mount poles. If your bracket arm is shorter (around 3–4 feet), a 2.5 x 4 ft flag gives a cleaner look. Match the flag's longer dimension to roughly half the pole length for proportional display.
Should I buy a nylon or polyester grand union flag?
Nylon is the better choice for most settings. It flies well in light breezes, dries fast after rain, and the UV-treated digitally printed colors hold up well through multiple seasons. Choose polyester only if you are in a consistently high-wind or coastal environment where the extra abrasion resistance justifies the heavier weight.
