FORTISVEX Illinois State Flag 6x10 Feet Nylon - Made in USA with Brass Grommets

This is the size where a state flag leaves residential territory behind. Sixty square feet is commercial, flown on a commercial flagpole, and it is the last size built with grommets before rope takes over.

This is the Illinois state flag at 6x10 Feet (60 square feet) in nylon, made in the United States and finished with brass grommets.

Built to the Illinois flag specification

The Illinois flag is set out in the Illinois State Designations Act at 5 ILCS 460. It is the state seal, showing an eagle, a shield and a boulder carrying the dates 1818 and 1868, on a white field, with the word Illinois added below in 1970.

The word Illinois was added in 1970.

Design, colors and the seal or emblem are what this state's statute defines; a fixed size for an outdoor flag is not among them. Most of the country works the same way, and that is why manufacturers all build to the same standard sizes.

The design here is reproduced faithfully, at the standard outdoor sizes the whole industry works in and that states buy for themselves. What actually matters on a flag flown outdoors is that the colors, the seal and the emblems are correct, and they are.

The law that defines it, in its own words

5 ILCS 460/5 reads:

(a) The reproduction of the emblem only on the "great seal of the State of Illinois" is authorized and permitted when reproduced in black or in the national colors upon a white sheet or background and bearing underneath the emblem in blue letters the word "Illinois" and being an actual reproduction of the great seal, except for the outer ring, for use as a State banner or insignia under the conditions and subject to the restrictions provided by the laws of the United States and the State of Illinois as to the United States or State flag or ensign.

Confirmed unchanged. The 2024 to 2025 Flag Commission vote favored the existing design and no new statute followed.

You do not have to take our word for any of that. Read 5 ILCS 460/5 in full at Justia, and check what we sell against it.

That is the flag we build, not a rough version of it.

What is on it and what it means

The boulder carries the dates 1818 and 1868, marking statehood and the seal redesign.

What most listings get wrong

An Illinois Flag Commission created by Public Act 103-0513 ran a public vote in 2024 and 2025. When the results were announced on March 6, 2025 the existing flag won overwhelmingly. No new flag was adopted, so anyone telling you Illinois has a new flag is wrong.

Where the Illinois flag flies

Each holds a significant Civil War battle flag collection. Connecticut's is at the Museum of Connecticut History in Hartford. Illinois has the State Military Museum in Springfield. Massachusetts has the State House Hall of Flags. Michigan runs a Save the Flags program with rotating display at the Capitol. Minnesota's Historical Society holds the First Minnesota's colors associated with Gettysburg.

The notable tall pole is Sterling Bay's two hundred foot flagpole in Chicago's Fulton Market, but the record cited for it concerns a thirty by sixty foot Ukrainian flag rather than a United States flag.

Fly it on Illinois’s birthday

Illinois became the 21st state on December 3, 1818. Under the United States Flag Code as amended July 7, 1976, a state flag flown on the state’s birthday takes its place beneath the United States flag, and that day is the one date every year the Illinois flag has an official reason to go up.

Buy it now and it is on the flagpole for the day. The full list of state birthdays is on our state birthdays page.

Nylon or polyester in Illinois

Nylon in most of the state. Polyester along the Lake Michigan lakefront at Chicago for lake driven wind, and in the open central and southern plains for storm wind.

This is a commercial flag at sixty square feet, and on the exposed sites named above, material choice separates a one-season flag from a three-season one.

What you have here is the nylon, appropriate for the sheltered and moderate wind sites listed above, for any house bracket, and for anywhere the flag is brought down during storms. Two things decide it: it is light, flying on an ordinary breeze rather than going limp, and it dries fast, which is the defense against mildew in humidity. The trade is ultraviolet durability — nylon’s amide bonds break under sun, fading and weakening faster than polyester, and it loses about a tenth of its strength wet. For an exposed site on the list above, the polyester version is worth a look instead.

One more thing that decides it, and it is the part people only learn after buying twice: a nylon flag flies on days a polyester flag will not. If the flag matters to you on a still morning, on a holiday, at a funeral, at a ceremony, that is an argument for this one even on a site where the polyester would last longer. A flag that hangs is not doing its job either.

Institutions commonly cite the American Legion’s figure: the federal government expects about ninety days from a flag flown daily sunrise to sunset, and roughly a quarter of that flown around the clock. On the ground, retailers report three to six months for nylon flown daily, four to eight for polyester, and one to three years for occasional flying. Take these as working estimates, not warranties — exposure can move them a long way in either direction.

How the 6x10 Feet is built

Four rows of stitching is enough for a house flag; sixty square feet is not a house flag, and the fly end needs six rows to handle the force it actually generates.

The math comes to 60 square feet of nylon at roughly two ounces a square yard. In a thirty mile an hour wind, the fly end moves faster than the wind that is driving it, since the wave headed for the tip speeds up as it travels — which explains why the tip wears out first and why fly-end stitching count is worth checking on any listing.

Proper folding at this size needs two people and clear ground. Sixty square feet is too much fabric for a tailgate fold.

A lock stitch ties into the stitch next to it, so one broken thread does not unzip the whole seam — it just stops. 6 rows is not 6 times the strength; it is 5 backups. Two inches of reinforced heavy duty white heading carries brass grommets and tooth washers here — the part of the flag under the most sustained strain at this size.

This is commercial grade nylon: light enough to fly in a light wind, quick to shed water instead of holding it, and fast to dry, which matters because a waterlogged flag is a heavier flag putting more strain on its seams. UV resistant, field tested ink is what fights the sun, which is the real driver of color loss over time.

Why this flag is harder to make than most

A detailed seal on white plus lettering. White fields also show soiling faster than any other ground color, which matters on a flag that flies year round.

For what it is worth, the North American Vexillological Association surveyed 72 state, provincial and territorial flags in 2001 and rated them from zero to ten. The Illinois flag placed 49, at 4.38 out of 10.

Will it fit my flagpole?

An in-ground flagpole thirty to forty feet tall suits this flag.

Questions about the 6x10 Feet

What size flagpole for a 6x10 foot flag? Thirty to forty feet. At this size the flag is commercial and the flagpole has to be an in-ground pole with a truck and halyard.

Why does the 6x10 foot flag have grommets when the 8x12 foot flag has a rope? Sixty square feet is the most two brass grommets can be asked to carry. Above this the load is spread along a rope sewn the length of the heading.

Does a 6x10 foot flag need a heavier flagpole? A sixty square foot flag in a gust loads a flagpole hard. If the pole was sold for a 4x6 foot or 5x8 foot flag, check its rating before stepping up.

The last size on grommets

Above this size, every flag switches to a full-length sewn rope instead of two grommets, because two points can no longer bear the load. The 6x10 foot flag sits right on that line, which is why it carries six rows of stitching and a two inch heading while still keeping grommets.

Which size do I need?

The rule that governs both tables is a length-to-height ratio of about one quarter to one third. Borderline cases favor the smaller size if you want it flying often and lasting, or the larger size if the point is to be seen from a distance.

If you know your flagpole height, start here.

• 6 Feet house bracket: 2x3 Feet or 3x5 Feet
• 15 to 20 Feet flagpole: 3x5 Feet or 4x6 Feet
• 20 to 25 Feet flagpole: 4x6 Feet or 5x8 Feet
• 25 to 35 Feet flagpole: 5x8 Feet or 6x10 Feet
• 35 to 45 Feet flagpole: 6x10 Feet or 8x12 Feet
• 45 to 60 Feet flagpole: 8x12 Feet or 10x15 Feet
• 60 to 80 Feet flagpole: 10x15 Feet or 12x18 Feet
• 80 to 100 Feet flagpole: 12x18 Feet or 15x25 Feet
• 100 to 120 Feet flagpole: 15x25 Feet or 20x30 Feet
• 120 to 150 Feet flagpole: 20x30 Feet or 20x38 Feet
• 150 to 200 Feet flagpole: 20x38 Feet or 30x50 Feet
• 200 to 240 Feet flagpole: 30x50 Feet or 30x60 Feet
• 240 Feet and above: 30x60 Feet or 50x80 Feet, engineered to the flagpole

If you know your flag size, start here.

• 2x3 Feet: 4 to 8 Feet bracket or garden flagpole
• 3x5 Feet: 6 Feet bracket, or 15 to 20 Feet in-ground flagpole
• 4x6 Feet: 18 to 25 Feet in-ground flagpole
• 5x8 Feet: 25 to 35 Feet flagpole
• 6x10 Feet: 30 to 40 Feet flagpole
• 8x12 Feet: 40 to 50 Feet flagpole
• 10x15 Feet: 50 to 60 Feet flagpole
• 12x18 Feet: 60 to 80 Feet flagpole
• 15x25 Feet: 80 to 100 Feet flagpole
• 20x30 Feet: 100 to 120 Feet flagpole
• 20x38 Feet: 120 to 150 Feet flagpole. This is the garrison size under Executive Order 10834, at a one to one point nine ratio rather than the two to three of the commercial sizes, and it is the size flown at the White House and the Capitol
• 30x50 Feet: 150 to 200 Feet flagpole
• 30x60 Feet: 200 to 240 Feet flagpole. This is the largest standard commercial size
• 50x80 Feet: 240 Feet and above, engineered to the flagpole

Push the flagpole past a hundred feet and the same ratio still applies, but it stops being a simple lookup: the flag, the truck, the halyard, the foundation and the wind load need to be engineered as a unit, and skipping that step damages the flagpole before it damages the flag. A number of famous large flags deliberately break the rule of thumb, on an engineer’s word rather than a table’s.

The full range is available to order even where a size is not shown on the site. If what you need is not listed here, ask and we can still get it made.

About the back of the flag

The reverse of a printed flag mirrors the front, which is ordinary and true of nearly every flag in the country. To have both faces read correctly requires a double sided construction: two flags joined with a liner in between, at about twice the material and twice the price. Single sided is the industry standard, and the sensible pick unless a state’s statute says otherwise.

Flying it with the United States flag

Title 4, Section 7 of the United States Flag Code sets the rule: no flag flies above the United States flag, and none takes its place to the right at the same level, meaning the viewer’s left. Two equal-height flagpoles put the United States flag on the viewer’s left, with both flags matched in size. Unequal flagpoles put the United States flag on the taller one, and a single flagpole with two flags carries the United States flag at the top. Civilians are not bound by penalty under the Flag Code, but it remains the standard institutions follow.

Buy two and they both last longer

Fly one for a month, then swap. Two flags rotated monthly will outlast three flags flown to destruction, because the fabric recovers when it rests and the fly end stops taking the same abuse in the same place. Take it down in severe weather; a flag left up through a real windstorm can take more damage in one night than in six normal months. And watch the fly end rather than the middle, because a few minutes with a needle when the fraying starts buys another season.

For cities, counties, schools and agencies

We regularly supply state flags to cities, school districts, fire and police departments, courthouses and state agencies. Tax exempt accounts run through the tax exempt page. Quantity pricing, replacement schedules, or a size that is not listed all go through the contact page.

Why buy it from us

This company is small and American, and what is on the site is in stock. Every flag here is made in the United States, uses UV resistant ink, and is built to the construction described above rather than priced down to a cheaper build. We would rather you buy one flag that lasts than replace three that do not. Orders over twenty five dollars get free shipping.
