FORTISVEX Montana State Flag 4x6 Feet Nylon - Made in USA with Brass Grommets

This is the first size that genuinely outgrows a house bracket and calls for a flagpole in the ground. The honest reason to buy a 4x6 foot flag is size, not looks.

This is the Montana state flag at 4x6 Feet (24 square feet) in nylon, made in the United States and finished with brass grommets.

Built to the Montana flag specification

The Montana flag is set out in Montana Code Annotated Section 1-1-502, at a two to three ratio. It is the state seal on blue with the word Montana in gold above.

Derived from the banner of the First Montana Infantry in the Spanish-American War and adopted in 1905; the word Montana was added in 1981 and the font standardized in 1985.

What the statute here fixes is the design, the colors and the seal or emblem; it does not fix a size for an outdoor flag to hit. That is the position in most of the country, and it is the reason every manufacturer settles on the same standard sizes.

The reproduction here is faithful to the design, in the standard outdoor sizes used industry wide and bought by the states themselves. On an outdoor flag, correct colors, seal and emblems are what counts, and that is what you get.

The law that defines it, in its own words

Montana Code Annotated Section 1-1-502 reads:

There is hereby established a state flag of Montana. The state flag of Montana shall be a flag having a blue field with a representation of the great seal of the state in the center and with golden fringe along the upper and lower borders of the flag; the same being the flag borne by the 1st Montana Infantry, U.S.V., in the Spanish-American War, with the exception of the device, "1st Montana Infantry, U.S.V."; and above the great seal of the state shall be the word "MONTANA" in helvetica bold letters of gold color equal in height to one-tenth of the total vertical measurement of the blue field.

The emblem itself is defined by reference to the great seal, so these words are the frame and not the whole picture.

You do not have to take our word for any of that. Read Montana Code Annotated Section 1-1-502 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 seal shows mountains, the Great Falls of the Missouri, a plow, a pick and a shovel, with the motto Oro y Plata, Gold and Silver.

Worth knowing about this flag

The flag was a military banner before it was a state flag, which is why the seal sits where it does. And the lettering above the seal is a late addition, only fixed as to font in 1985.

Where the Montana flag flies

A private flagpole of a hundred and thirty feet flying a thirty by sixty foot flag in the Moiese Valley, Sanders County. The owner told the Daily Inter Lake he surveyed other poles at around a hundred feet and believes his is the state's tallest.

Fly it on Montana’s birthday

Montana became the 41st state on November 8, 1889. 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 Montana flag has an official reason to go up.

Order it ahead of the date and it is ready to fly that day. Every state’s birthday is listed on our state birthdays page.

Nylon or polyester in Montana

Polyester on the wind scoured plains and Rocky Mountain Front. Great Falls is among the windiest American stations, and Billings sees chinook winds. Nylon only in sheltered western valleys at Missoula.

For scale, the National Weather Service ultraviolet index forecast for Billings on July 23, 2026 was 9 at solar noon, in the very high band. That is the sun this flag has to survive.

Wind load becomes a real factor at twenty four square feet, and the verdict above matters more at this size than it does for a 3x5 Feet house flag.

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 figure most institutions use is from the American Legion, citing the United States government's expectation of about ninety days for a flag flown daily from sunrise to sunset, and roughly a quarter of that around the clock. Retailers see three to six months in practice for nylon flown daily, four to eight for polyester, and one to three years when flown occasionally. These are practical figures, not a guarantee, and real-world exposure shifts them considerably.

How the 4x6 Feet is built

With well over half again the area of a 3x5 foot flag, a 4x6 Feet catches proportionally more wind, and the fly end pays for it. It carries four rows of lock stitching, and needs every one.

The arithmetic behind that: 24 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.

A one person job, technically, but the first windy day taking it down alone will make the size difference clear. Bring it in ahead of weather, not during 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 solid brass grommets with tooth washers sit in a reinforced, inch and a half heavy duty white heading. Twenty four square feet puts genuine load on those two points.

The flag material is commercial grade nylon. It is light enough to fly in a gentle breeze, it sheds water rather than holding it, and it dries fast, which matters because a flag that stays wet stays heavy and works its seams harder. The ink is UV resistant and field tested; sun is what takes a flag’s color, and the ink decides how long it holds.

Why this flag is harder to make than most

A landscape seal with tools and a Spanish motto, plus lettering. Landscape detail at flag scale is the hardest thing to print well.

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 Montana flag placed 70, at 3.00 out of 10.

Will it fit my flagpole?

It suits an in-ground flagpole of eighteen to twenty five feet. On a six foot house bracket it will drag and wrap.

Questions about the 4x6 Feet

What flagpole does a 4x6 foot flag need? An in-ground flagpole of eighteen to twenty five feet. It is too large for a standard house bracket, which is the honest reason to choose it.

Is a 4x6 foot flag worth it over a 3x5 foot flag? Only if the flagpole is tall enough. On a twenty foot flagpole a 3x5 foot flag looks lost and a 4x6 foot flag fills it. On a six foot bracket the 4x6 foot flag will wrap.

Can I fly a 4x6 foot state flag with a 4x6 foot United States flag? Yes, and on two flagpoles of equal height that is the correct pairing, with the United States flag to the viewer’s left.

Where the step up starts to cost you

Going from a 3x5 foot flag to a 4x6 foot flag is where buying cheap begins to be expensive. The extra area means more force at the fly end and more load on the grommets, so a 4x6 Feet built to a budget fails faster than a 3x5 Feet built the same way. This is the size where construction stops being a nicety.

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

• 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

Above roughly a hundred feet of flagpole, the quarter to a third guide keeps its accuracy but loses its simplicity: the flag now has to be specified alongside the truck, the halyard, the foundation and the wind load as a single system, and skipping that step is how a flagpole gets damaged rather than the flag. Several famous installations fly flags larger than the rule on purpose, with an engineer deciding it rather than a table.

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

Hold a printed flag up to the light and the reverse side shows the design in mirror image. That is not a defect — it is how nearly every flag flown in America is made. A flag correct on both sides is a double sided flag, two flags sewn together around a liner, and it runs roughly double the price and double the weight. Unless a state’s own statute calls for it, single sided is standard and it is the right call.

Flying it with the United States flag

Title 4, Section 7 of the Flag Code is the source for this. The United States flag is never subordinate in position — nothing flies above it, and nothing takes its place at the viewer’s left when flags are level with each other. On matched flagpoles, the United States flag takes the viewer’s left and the flags should be sized the same; on unequal flagpoles, it goes on the taller one; and on a single pole flying two flags, it goes at the top. There is no penalty for civilians who do not follow the Code, but institutions treat it as the standard regardless.

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

Municipalities, school districts, fire and police departments, courthouses and state agencies all buy state flags from us regularly. The tax exempt page handles tax exempt accounts, and the contact page is the route for quantity orders, replacement schedules or a size not shown here.

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.
