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

This is the default: the size that fits the bracket already on the house, and the size Americans replace more than any other. When someone says flag without qualifying it, this is what they mean.

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

The statute for this flag describes the design, the colors and the seal or emblem, but it does not fix an overall size that a modern outdoor flag has to match. That is the normal position across most of the country, and it is why every manufacturer builds state flags in the same standard sizes.

What we build is a faithful reproduction of that design, sized to the standard outdoor sizes every manufacturer uses and the states themselves order in. On an outdoor flag, the colors, the seal and the emblems are what has to be right, and here they are.

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.

It is the real flag we produce, not a simplified version.

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.

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 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.

A house flag at fifteen square feet lives or dies on material choice for two reasons: flying in light wind, and drying speed after rain.

This listing is nylon, right for the sheltered and moderate wind sites above, for a standard house bracket, and for anywhere you take the flag down before a storm. Two things make it the pick. It flies on the breeze most yards actually see instead of hanging flat, being light, and it dries fast, which fights mildew where humidity is high. What it sacrifices is ultraviolet resistance: nylon’s amide bonds absorb and break under sun, losing strength and color faster than polyester, plus roughly a tenth of its strength while wet. For an exposed site from the list above, the polyester version is the better choice.

One more consideration, learned by most people only after a repeat purchase: a nylon flag moves in conditions where polyester hangs still. If the flag needs to actually be flying — a calm morning, a holiday, a funeral, a ceremony — that is an argument for nylon even on a site where polyester would technically outlast it. A flag that just hangs there has failed just as much as one that frays.

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 3x5 Feet is built

The fly end is where this size gives out, and it gives out sooner than it should on most flags people buy, because the 3x5 foot flag is bought on price more than any other size. Four rows of lock stitching on the fly end is the difference between one season and three.

Work the numbers and you get 15 square feet of nylon at roughly two ounces a square yard. At thirty miles an hour, the fly end actually outpaces the wind, because the wave running to the tip accelerates along the way — the reason the tip fails first, and the reason fly-end stitching count is the number that matters.

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.

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. The heading is heavy duty white and reinforced, an inch and a half wide, with two solid brass grommets. Fifteen square feet is enough sail area to work the grommets hard on a windy site.

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?

Built for the most common residential pairing in the country: a five or six foot house bracket, or an in-ground flagpole between fifteen and twenty feet.

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?

Both tables follow the same logic. A flagpole reads best with a flag whose length falls between a quarter and a third of its height. Where a size could go either way, smaller means more flying days and a longer life, bigger means more visibility at range.

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 website does not show every size we can supply. If yours is missing from the listing, the full range above is still available to order.

About the back of the flag

The back of a printed flag shows the design reversed, not missing. That is true of almost every flag in the country, and it is normal rather than a flaw. Getting both sides to read correctly means sewing two flags together with a liner between them, which roughly doubles the cost and the weight. Single sided is standard practice, and the right choice unless a particular state’s law says otherwise.

Flying it with the United States flag

The United States Flag Code, Title 4, Section 7, governs this. No other flag goes above the United States flag, or to its right when on the same level, which is the viewer’s left. On two flagpoles of the same height the United States flag takes the viewer’s left and both flags should be the same size. If the flagpoles differ in height, the United States flag goes on the taller one. On a single flagpole carrying two flags the United States flag goes at the top. The Flag Code is advisory for civilians and carries no penalty, but it is the standard every institution follows.

Buy two and they both last longer

Keep two flags and swap them monthly. That single habit will outlast three flags run to destruction, since resting fabric recovers and the fly end is spared the repeated wear of constant flying. Take the flag down ahead of severe weather, since one bad storm night can outdo six calm months. Watch the fly end rather than the center; a little stitching early saves a whole 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

A small American company runs this store, and everything listed here is something we actually stock. Every flag is made in the United States, printed in UV resistant ink, and built to the construction described above rather than built down to a price. We would rather one flag last than sell three that fail early. Free shipping kicks in over twenty five dollars.
