FORTISVEX South Dakota 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 South Dakota state flag at 5x8 Feet (40 square feet) in nylon, made in the United States and finished with brass grommets.

Built to the South Dakota flag specification

The South Dakota flag is set out in South Dakota Codified Laws Section 1-6-4, at a ratio of about three to five. It is a sky blue field with the state seal on a serrated gold sun, and the words South Dakota and The Mount Rushmore State.

Originally adopted in 1909 as The Sunshine State, redesigned in 1963, with the current nickname version adopted in 1992.

South Dakota specifies a ratio. Section 1-6-4 gives a field one and two thirds as long as it is wide, which is three to five, and defines the seal, the sun and the lettering as fractions of the width. A 3x5 foot flag matches the ratio.

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

South Dakota Codified Laws Section 1-6-4 reads:

The state flag or banner shall consist of a field of sky-blue one and two-thirds as long as it is wide. Centered on such field shall be the great seal of South Dakota made in conformity with the terms of the Constitution, which shall be four-ninths the width of the flag in diameter. The seal shall be on a white background with the seal outlined in dark blue or, in the alternative, shall be on a sky-blue background with the seal outlined in dark blue thereon. Surrounding the seal in gold shall be a serrated sun whose extreme width shall be five-ninths the width of the flag. The words "South Dakota" symmetrically arranged to conform to the circle of the sun and seal shall appear in gold letters one-eighteenth the width of the field above the sun and seal and the words "The Mount Rushmore State" in like-sized gold letters and in like arrangement shall appear below the sun and seal. Flags designed of such material as may be provident for outdoor use need have no fringe but flags for indoor and display usage shall have a golden fringe one-eighteenth the width of the flag on the three sides other than the hoist.

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 South Dakota Codified Laws Section 1-6-4 in full at the South Dakota Legislature, 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 sits on a serrated gold sun, which carries over from the original 1909 design when the flag was called the Sunshine State flag.

What most listings get wrong

The nickname on the flag changed. Before 1992 it read The Sunshine State. Flags reading Sunshine State are pre-1992 and are no longer current.

Where the South Dakota flag flies

A genuine state capitol program. Requests to have a flag flown over the State Capitol are handled by the Bureau of Administration's Property Management division in Pierre, with about three weeks' notice requested and the requester covering the cost of the flag plus mailing. Exact price, sizes, materials and any residency limit were not published in the sources found. The Bureau's Central Supply separately sells United States, South Dakota and prisoner of war flags. A distinctive history: one of the two original 1909 handmade state flags, linked to the Old West lawman Seth Bullock and designed by Ida Anding, was displayed for decades in the Secretary of State's office at the Capitol, went missing in January 2015, and was recovered in Washington later that year. A separate Memorial Flag Program running since 1987 flies flags for deceased veterans in Hilgers Gulch Park.

Fly it on South Dakota’s birthday

South Dakota became the 40th state on November 2, 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 South Dakota flag has an official reason to go up.

Buy it in time and it goes up on the day it matters. Every state’s date is on our state birthdays page.

Nylon or polyester in South Dakota

Polyester statewide at Sioux Falls and Rapid City.

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.

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.

Here is the part usually learned the hard way, after a second purchase: nylon catches wind on days polyester simply will not move. When the flag needs to be visibly flying — a quiet morning, a holiday, a funeral, a ceremony — that argues for nylon even on a site where polyester would technically last longer. A flag that just hangs there 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 5x8 Feet is built

Forty square feet of flag on a business flagpole fails visibly, from the road, the same vantage point it was put up to be seen from in the first place.

Here is the arithmetic: 40 square feet of nylon at roughly two ounces a square yard. A thirty mile an hour wind sends the fly end moving faster than the wind itself, since the wave traveling toward the tip picks up speed as it goes — which is why the tip wears out first, and why the fly end's stitching count is the figure to check on any listing.

Two people handle this more easily than one, especially on a windy site, since forty square feet of unsecured fabric catches wind during folding.

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. This size steps the heading up to two inches, heavy duty white and reinforced, with brass grommets and tooth washers. Forty square feet in a gust pulls hard, and that extra half inch of heading earns its place.

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 busy seal, a serrated sun and two lines of lettering, one of them long. Among the most crowded designs in the country.

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 South Dakota flag placed 68, at 3.12 out of 10.

Will it fit my flagpole?

It suits an in-ground flagpole of twenty five to thirty five feet. This is the standard commercial pairing.

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

Anyone driving past a business sees the flag before they see the building. A faded, frayed flag outside a place of business says something about the business, and it is a different kind of cost from the price of replacing it.

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.

• 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 rule keeps holding above a hundred feet of flagpole, but the buying decision does not stay simple: the flag, the truck, the halyard, the foundation and the wind load now have to be specified as one engineered system, and a flag chosen without checking the flagpole rating puts the pole at risk before the flag. Some of the most recognizable flags in the country deliberately run larger than the rule, always with an engineer behind that call.

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 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

Buy two flags and swap them every month. That habit alone outlasts three flags flown into the ground, since the material recovers while resting and the fly end is not repeatedly stressed in the same place. Take the flag down for real storms; overnight wind damage can exceed six months of ordinary wear. Inspect the fly end rather than the middle, and a few minutes of repair stitching when fraying starts buys another season.

For cities, counties, schools and agencies

Fire and police departments, school districts, courthouses, municipalities and state agencies are all regular buyers of our state flags. Tax exempt purchasing is set up through the tax exempt page, and quantities, replacement schedules or an unlisted size are handled 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.
