FORTISVEX Illinois State Flag 3x5 Feet Nylon - Made in USA with Brass Grommets

The 3x5 foot flag is the one most people mean when they say flag. It is the default house size, it fits the bracket that came with the house, and it is the size replaced most often in America.

This is the Illinois state flag at 3x5 Feet (15 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.

The design, the colors and the seal or emblem are set by statute; the size of a modern outdoor flag is not. That is the case in most of the country, and it is why manufacturers across the industry all build to the same standard sizes.

Faithfully reproduced, that is the standard we hold this design to, at the outdoor sizes the whole industry uses and states themselves order. What an outdoor flag needs right is the color, the seal and the emblems, and this one has them right.

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 the flag we make. Not an approximation 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.

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.

At fifteen square feet, a house flag, the flag material decides whether it flies on a light day and how fast it dries after rain.

You are looking at the nylon here, the right pick for the sheltered and moderate wind sites named above, for any house bracket, and for anywhere the flag gets brought in during storms. Two things make that case. It is light enough to move on the breeze most yards actually get rather than hang limp, and it dries fast, which keeps mildew away in a humid climate. What it trades away is ultraviolet durability — nylon’s amide bonds break down under ultraviolet light, losing strength and color faster than polyester, and it loses roughly a tenth of its strength while wet. For one of the exposed sites named above, the polyester version is the better fit.

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.

The benchmark institutions generally lean on comes from the American Legion: the federal government's own expectation is about ninety days for a daily sunrise-to-sunset flag, and roughly a quarter of that flying around the clock. Retailers report three to six months for nylon flown daily, four to eight months for polyester, and one to three years for occasional flying. Treat those as working estimates rather than a warranty, since exposure can shift them a great deal.

How the 3x5 Feet is built

Because the 3x5 foot flag is the size bought most often on price alone, it is also the size that fails first at the fly end. Four rows of lock stitching there is what buys the extra two seasons.

The arithmetic behind that: 15 square feet of nylon at roughly two ounces a square yard. In a thirty mile an hour wind the fly end of a flag this size travels faster than the wind itself, because the wave running out to the tip accelerates as it goes. That is why the tip wears out first and why the stitching count at that end is the number worth reading on any listing.

This is a one person job to raise or lower, folding down to drawer size. Rotating two flags monthly costs you a minute at this size, nothing more.

Each lock stitch knots into the one beside it, so a broken thread stays broken right where it snapped instead of unraveling the whole seam. 4 rows is not 4 times the strength — it is 3 backups. Two solid brass grommets sit in a reinforced, inch and a half heading. At fifteen square feet, there is enough sail area to put real strain on them whenever the site sees wind.

The material here is commercial grade nylon. Its lightness lets it fly on a gentle breeze, it sheds rather than absorbs water, and it dries quickly, sparing the seams the extra weight and strain of staying wet. Field tested UV resistant ink handles the part that actually determines fade life: sun exposure.

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?

It suits a five or six foot house bracket, or an in-ground flagpole of fifteen to twenty feet. That is the most common residential setup in the country and this is the size built for it.

Questions about the 3x5 Feet

What size flagpole does a 3x5 foot flag need? A six foot house bracket, or an in-ground flagpole of fifteen to twenty feet. It is the most common residential pairing in the country.

How long does a 3x5 foot nylon flag last outside? The federal working figure is about ninety days for a flag flown daily from sunrise to sunset, and about a quarter of that flown around the clock. Retailers commonly see three to six months in daily use and one to three years flown on occasions only.

Is this flag printed or sewn? The design is printed in UV resistant ink on one side and reads through in reverse on the back, which is how nearly every state flag sold in the country is made. The construction, the heading, the stitching and the grommets are sewn.

Why this size gets replaced most

There is nothing weaker about the 3x5 foot flag itself — it is just the size most often bought on price, and built to match. A cheap one with one or two rows of stitching on the fly end frays inside a season and is six inches shorter within two. The construction is what separates the two.

Which size do I need?

Underneath both tables is a single ratio: a flag a quarter to a third the flagpole’s height. When you land between two rows, that is a real choice, not a rounding error — smaller flies more often, bigger reads further.

• 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

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

The quarter to a third rule holds all the way up, but above about a hundred feet the flag and the flagpole stop being two purchases and become one engineered system: the truck, the halyard, the foundation and the wind load all have to be specified together, and a flag bought without checking the flagpole rating damages the flagpole first. Several famous installations deliberately fly longer than the rule, which is a choice made with an engineer rather than from a chart.

We supply the whole range shown above, whether or not a given size currently has its own listing on the site. Ask if you do not see it.

About the back of the flag

It is normal for a printed flag to read backward from behind — almost every flag flown in America works this way. A flag that reads correctly from both sides is double sided: two flags sewn together with a liner, at roughly double the weight and cost. Single sided stays the standard and the right choice except where a state’s own law requires the double sided build.

Flying it with the United States flag

The rule comes from Title 4, Section 7 of the United States Flag Code: no flag is displayed above the United States flag, and none is placed to its right at the same level, which from the viewer’s position means the left. Equal-height flagpoles carry the United States flag on the viewer’s left with matching flag sizes; unequal flagpoles put it on the taller one; a single flagpole with two flags carries it at the top. Civilians face no penalty for departing from the Flag Code, but it is the standard institutions hold to.

Buy two and they both last longer

The simplest way to make a flag last is to own two and rotate them monthly — that alone outlasts three flags flown to failure, because rest lets the fabric recover and the fly end is not hammered day after day. Take it down ahead of real storms, since one bad night of wind can undo six good months. Watch the fly end, where fraying starts, and a quick repair there is worth a whole extra season.

For cities, counties, schools and agencies
