Wyoming 10x15 Feet Nylon State Flag Made in USA

A 10x15 foot flag exists to be seen from a distance — a hundred and fifty square feet does that. It also demands a flagpole and hardware sized to carry it.

This is the Wyoming state flag at 10x15 Feet (150 square feet) in nylon, made in the United States and finished with a sewn rope and plated steel thimbles.

Built to the Wyoming flag specification

The Wyoming flag is set out in Wyoming Statutes Section 8-3-102, with the seal at Section 8-3-101, at a seven to ten proportion. It is a blue field bordered in white then red, with a white bison silhouette carrying the state seal in blue on its flank.

Designed by Verna Keays for a Wyoming Daughters of the American Revolution contest in 1916 and adopted January 31, 1917.

Wyoming specifies proportions rather than a size. Section 8-3-102 sets the width at seven tenths of the length and defines the border, the stripe, the bison and the seal as fractions of the whole. Seven to ten is not a standard commercial size, and vexillologists have noted for years that manufacturers do not build to it.

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

Wyoming Statutes Section 8-3-102, subsection (a) reads:

A state flag is adopted to be used on all occasions when the state is officially and publicly represented. All citizens have the privilege of use of the flag upon any occasion they deem appropriate. The width of the flag shall be seven-tenths (7/10) of its length; the outside border shall be in red, the width of which shall be one-twentieth (1/20) of the length of the flag; next to the border shall be a stripe of white on the four (4) sides of the field, which shall be in width one-fortieth (1/40) of the length of the flag. The remainder of the flag shall be a blue field, in the center of which shall be a white silhouetted buffalo, the length of which shall be one-half (1/2) of the length of the blue field; the other measurements of the buffalo shall be in proportion to its length. On the ribs of the buffalo shall be the great seal of the state of Wyoming in blue. The seal shall be in diameter one-fifth (1/5) the length of the flag. Attached to the flag shall be a cord of gold with gold tassels. The same colors shall be used in the flag, red, white and blue, as are used in the flag of the United States of America.

You do not have to take our word for any of that. Read Wyoming Statutes Section 8-3-102 in full at Justia, and check what we sell against it.

That is the flag as we build it. Nothing about it is approximate.

What is on it and what it means

The bison is the plains and the state’s wildlife. The seal branded on its flank represents livestock and the branding heritage. The seal figures carry Equal Rights, for Wyoming as the first territory to grant women the vote, alongside livestock, mining and grain.

Worth knowing about this flag

Keays drew the bison facing the fly. The version adopted reversed it to face the hoist, which is the one you fly today.

Where the Wyoming flag flies

Wyomingites obtain United States Capitol flags through the congressional delegation, residents only, with a flying and certificate fee plus shipping. the Governor routinely orders the Wyoming State flag specifically flown at half staff at the Capitol, sunrise to sunset, to honor individuals. The Capitol's gold leaf gilded copper dome, one of only about ten gold domed American capitols, was re-gilded five times, most recently during the 2016 to 2019 Capitol Square restoration, when a new copper dome and gilded finial were installed and the Capitol reopened on July 10, 2019.

Fly it on Wyoming’s birthday

Wyoming became the 44th state on July 10, 1890. 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 Wyoming 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 Wyoming

Polyester statewide. Cheyenne at roughly 12.9 to 14.6 miles per hour is among the windiest American stations, and the state is known for relentless wind and high altitude ultraviolet.

Even polyester needs regular replacement here.

A hundred and fifty square feet rules nylon out as a serious option on the exposed sites above. Confirm the flagpole and truck rating before ordering either material.

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.

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 10x15 Feet is built

Six rows of lock stitching on the fly end with zig zag stitched corners. At this area the wave running out to the tip is moving fast enough that the corner seams are the first thing the wind tries.

Work the numbers and you get 150 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.

Plan the handling before it arrives. A hundred and fifty square feet needs two people who have agreed what they are doing, on a day that is not windy, with the halyard already sorted.

With lock stitching, every stitch knots into its neighbor, so damage stays contained at the break instead of running down the seam. Read 6 rows not as 6 times the strength but as 5 backups. At this size a grommet would fail outright, so the heading instead carries a nylon rope its full length, finished with two plated steel thimbles.

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 large bison silhouette is straightforward, but the seal branded on its flank is fine detail inside a shape, which is harder than a seal on an open field.

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 Wyoming flag placed 23, at 6.28 out of 10.

Will it fit my flagpole?

A fifty to sixty foot in-ground flagpole, with truck and halyard rated to carry it, suits this size.

Questions about the 10x15 Feet

What size flagpole for a 10x15 foot flag? Fifty to sixty feet, and the truck and halyard must be rated for a hundred and fifty square feet in a gust.

Is a 10x15 foot flag too big for my flagpole? If the flagpole was not specified for it, yes. An oversized flag damages the flagpole before it damages itself.

How is a 10x15 foot flag shipped? Rolled where possible, folded where it must be. Creases from folding relax within days of flying.

Check the flagpole before the flag

This size, a hundred and fifty square feet, can exceed what a flagpole was built to carry. Check the flagpole and truck rating before ordering — an oversized flag damages an undersized flagpole before it damages itself.

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

Nothing about the ratio breaks above a hundred feet, but the purchase does: the flag, the flagpole, the truck, the halyard and the foundation become one system that has to be specified together, and skipping that check risks the flagpole before it risks the flag. Some of the largest flags flown in the country are deliberately oversized for their rule-of-thumb flagpole, always on an engineer’s sign-off.

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

One flag flown month after month wears faster at the same point every time; two flags rotated monthly outlast three run to failure, because rest lets fabric recover. Bring the flag in ahead of severe weather — a hard storm overnight can outdo six normal months. And check the fly end first, since that is where fraying starts, and a small stitch repair there is worth a full extra season.

For cities, counties, schools and agencies

State flags go out to municipalities, school districts, fire and police departments, courthouses and state agencies as a matter of course. Tax exempt purchasing runs through the tax exempt page, and anything involving quantity, a replacement schedule or a size we do not list goes through the contact page.

Why buy it from us

This is a small American company, and what you see listed is what we actually stock. Every flag is made in the United States, printed with UV resistant ink, and built to the construction described above, not to whatever a price point demands. Selling one flag that lasts beats selling three that fail. Orders over twenty five dollars ship free.
