FORTISVEX Idaho State Flag 8x12 Feet Nylon - Made in USA with Rope and Thimbles

The 8x12 foot flag belongs to institutions: civic buildings, campuses, large commercial sites, on a flagpole forty to fifty feet tall. This is not a size anyone ends up with by accident.

This is the Idaho state flag at 8x12 Feet (96 square feet) in nylon, made in the United States and finished with a sewn rope and plated steel thimbles.

Built to the Idaho flag specification

The Idaho flag is set out in Idaho Code Section 46-801. It is the state seal on a blue field with a red and gold band reading State of Idaho. The statute describes a silk ceremonial color, five feet six inches by four feet four inches with gilt fringe, which is the pattern flag the state keeps rather than the size anyone flies outdoors.

Adopted in 1907.

Idaho Code Section 46-801 describes a silk flag five feet six inches by four feet four inches on a pike with two and a half inch gilt fringe and a twenty one inch seal. Those are the dimensions of a ceremonial parade color from 1907, not of an outdoor flag, and no manufacturer in the country stocks that size.

We build a faithful reproduction of that design at the standard outdoor sizes the industry uses, the same sizes states order for themselves. Correct colors, seal and emblems are what an outdoor flag has to get right, and that is what this one gets right.

The law that defines it, in its own words

Idaho Code Section 46-801, State Flag reads:

A state flag for the state of Idaho is hereby adopted, the same to be as follows: A silk flag, blue field, five (5) feet six (6) inches fly, and four (4) feet four (4) inches on pike, bordered with gilt fringe two and one-half (2 1/2) inches in width, with state seal of Idaho twenty-one (21) inches in diameter, in colors, in the center of a blue field. The words "State of Idaho" are embroidered in with block letters, two (2) inches in height on a red band three (3) inches in width by twenty-nine (29) inches in length, the band being in gold and placed about eight and one-half (8 1/2) inches from the lower border of fringe and parallel with the same.

You do not have to take our word for any of that. Read Idaho Code Section 46-801 in full at the Idaho Legislature, and check what we sell against it.

That is the flag we build, not a rough version of it.

What is on it and what it means

The seal shows a miner and a woman representing liberty, justice and equality, and reflects mining, forestry, farming and the state’s wildlife.

What most listings get wrong

The seal on this flag is the only state seal in the country designed by a woman, Emma Edwards Green, in 1891. Almost nobody selling this flag mentions her. Note also that the words State of Idaho appear both on the red and gold band and again inside the seal itself. That is not a printing mistake, it is the flag as Idaho Code Section 46-801 specifies it.

Emma Edwards Green designed the seal in 1891. No other state seal was designed by a woman.

Where the Idaho flag flies

Idahoans obtain United States Capitol flags through the congressional delegation. Idaho Code Section 67-820 provides that when the flag is flown at half staff at the capitol for a line of duty death, the flag flown over the capitol building in honor of the deceased shall be presented to the family. The Idaho State Historical Society documents that the copper eagle atop the Capitol dome was fabricated from parts of the battleship Idaho and was re-gilded with gold leaf during the 2005 to 2010 restoration. The state flag descends from the battle flag of the First Idaho Infantry carried in the Philippines in 1899.

Fly it on Idaho’s birthday

Idaho became the 43rd state on July 3, 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 Idaho flag has an official reason to go up.

Nylon or polyester in Idaho

Nylon in the sheltered Treasure Valley at Boise, Nampa and Meridian. Polyester across the wind exposed Snake River Plain and Magic Valley at Twin Falls, Pocatello and Idaho Falls.

For scale, the National Weather Service ultraviolet index forecast for Boise on July 23, 2026 was 10 at solar noon, in the very high band. That is the sun this flag has to survive.

This size, ninety six square feet, puts real load on a flagpole. On the exposed sites above polyester is not optional — it is the only sensible call, and the hardware needs to be rated for it.

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.

This is the detail people usually only figure out after buying twice: nylon will fly on a day too calm for polyester to move at all. If flying on a still morning, a holiday, at a funeral, or at a ceremony matters to you, that is reason enough to choose nylon even where polyester would survive longer. A motionless flag fails at its purpose regardless of how durable it is.

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 8x12 Feet is built

Six rows of lock stitching on the fly end, and the corners are zig zag stitched rather than run straight, because a straight seam at a corner can be worked open by the wind over a season.

The math comes to 96 square feet of nylon at roughly two ounces a square yard. In a thirty mile an hour wind, the fly end moves faster than the wind that is driving it, since the wave headed for the tip speeds up as it travels — which explains why the tip wears out first and why fly-end stitching count is worth checking on any listing.

Two people on the ground, two people at the flagpole: this size demands it. Ninety six square feet can knock you off balance in a gust while clipping it on alone.

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. 6 rows is not 6 times the strength — it is 5 backups. This size drops grommets entirely. The heading carries a nylon rope its full length, ending in plated steel thimbles, so the load runs through the rope instead of two vulnerable points.

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 highly detailed painterly seal with two human figures. This is among the most expensive state flags to reproduce accurately and the fine detail is what separates a good one from a cheap one.

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 Idaho flag placed 64, at 3.17 out of 10.

Will it fit my flagpole?

A forty to fifty foot in-ground flagpole with proper truck and halyard hardware suits this size, not a house bracket.

Questions about the 8x12 Feet

What size flagpole for an 8x12 foot flag? Forty to fifty feet, on a truck and halyard rated for the load. This is an institutional flag.

What are the thimbles for? The rope sewn through the heading ends in two plated steel thimbles. The halyard snaps clip to the thimbles, so the pull runs through the rope along the whole hoist rather than tearing at two grommets.

Can an 8x12 foot flag fly around the clock? It can, on a lit flagpole, but a flag flown twenty four hours lasts roughly a quarter as long as one flown sunrise to sunset. Budget for that.

Why rope and thimbles carry most of the load

Two grommets concentrating ninety six square feet of pull onto two small brass rings does not hold, which is why a single reinforced grommet at the center of the heading now serves only as a secondary attachment point. A rope sewn the length of the heading spreads that load across the entire hoist and lets the thimbles take the attachment. It is more expensive to build and it is the only way a flag this size survives.

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.

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 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

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

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

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.
