FORTISVEX Illinois State Flag 5x8 Feet Nylon - Made in USA with Brass Grommets

Businesses fly this size on thirty foot flagpoles: dealerships, banks, fire stations, churches, schools. A homeowner with a tall flagpole reaches for it too, once a 4x6 foot flag starts looking small up there.

This is the Illinois state flag at 5x8 Feet (40 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.

This state's statute covers the design, the colors and the seal or emblem, and stops there — it sets no overall size for a modern outdoor flag to match. Most states take the same approach, which is exactly why every manufacturer builds state flags in 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.

This is what we actually make, not a stand-in for 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.

Have it on hand before the date arrives and it is on the flagpole in time. The full state-by-state list 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.

Forty square feet puts real load on the heading in any gust, and an exposed site from the list above will show the difference between materials inside a single season.

This is the nylon listing, suited to the sheltered and moderate wind sites named above, to any house bracket, and to anywhere you bring the flag in during storms. Two factors drive that choice. Nylon is light, catching the breeze most yards actually get instead of hanging still, and it dries quickly, which is what keeps mildew at bay in humid air. The cost is ultraviolet life: nylon’s amide bonds absorb and break under ultraviolet exposure, fading faster than polyester, and it loses about a tenth of its strength wet. On one of the exposed sites named above, look instead at the polyester version.

There is one more factor, and most people only discover it after buying the wrong material once: a nylon flag moves on days a polyester flag stays limp. If it matters to you that the flag is actually flying on a still morning, a holiday, at a funeral, at a ceremony, that favors nylon even where polyester would outlast it. A flag hanging motionless has failed at its job too.

Most institutions work from the same benchmark, reported by the American Legion: the United States government's expectation is roughly ninety days for a flag flown daily sunrise to sunset, and about a quarter of that for one flown around the clock. In practice, retailers report three to six months for nylon flown daily, four to eight for polyester, and one to three years for a flag flown only on occasions. These are working numbers, not a guarantee, and exposure can move them substantially either way.

How the 5x8 Feet is built

Forty square feet is real work for a flag, and this one fails where everyone can see it. A frayed tip on a business flagpole shows from the road — which is exactly why the flag is flying.

The math comes to 40 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.

This size is easier with two people, particularly when it is windy — forty square feet of loose material will catch the wind while one person tries to fold it.

Lock stitching means each stitch is knotted into the next, so a broken thread stops where it broke rather than unzipping the seam. 4 rows does not mean 4 times the strength; it means 3 backups. Two inches of heavy duty white, reinforced heading holds brass grommets and tooth washers here, because forty square feet in a gust is a serious pull, and half an inch of extra heading is not for looks.

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 of twenty five to thirty five feet is the pairing most commercial sites use for this size.

Questions about the 5x8 Feet

What size flagpole for a 5x8 foot flag? Twenty five to thirty five feet in the ground, which is the standard commercial flagpole. This is the size on most dealerships, banks and fire stations.

Should a business choose nylon or polyester at 5x8 Feet? Nylon flies more often and looks better on a calm day. Polyester lasts longer on an open, windy or coastal site. The section above names which your state is.

How often does a 5x8 foot commercial flag need replacing? A flag flown daily on an exposed commercial flagpole is typically replaced two to four times a year. A rotation of two flags swapped monthly stretches that.

What the condition of it says

Before the building registers, the flag does — that is what anyone driving past a business sees first. A frayed, faded flag communicates something, and the cost of that is separate from what replacing it would run.

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.

• 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.

Every size in both tables can be ordered, listed here or not. If the size you want does not appear on the website, contact us and we can still supply it.

About the back of the flag

A single sided printed flag shows its design correctly on one face and reversed on the other. That is expected, and it describes almost every flag flying in the United States. A flag readable on both sides is built as two layers sewn around a liner, roughly double the cost and double the weight of a single sided flag. Unless a state’s law requires double sided, single sided remains the standard choice.

Flying it with the United States flag

This is governed by the United States Flag Code, Title 4, Section 7: the United States flag always outranks every other flag in position, never displayed below it or to its right at the same level — right from the viewer’s side, that is. Two flagpoles of equal height place the United States flag at the viewer’s left with both flags the same size; if the poles differ in height, it goes on the taller pole; on one pole flying two flags, it sits at the top. The Flag Code carries no penalty for private citizens, but institutions treat it as the standard.

Buy two and they both last longer

Alternate two flags on a monthly schedule and you will get more life from both than from three flags flown until they wear out, because resting fabric recovers and the fly end stops absorbing the same repeated stress. A severe storm is the one condition worth taking the flag down for; it can do more damage in a night than six calm months. The fly end frays first, not the center, and stitching it early adds a 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.
