FORTISVEX California State Flag 10x15 Feet Nylon - Made in USA Bear Flag with Rope and Thimbles

This is a large installation flag: a hundred and fifty square feet, visible from a real distance, which is the whole point of choosing it. The flagpole and hardware have to be built to match.

This is the California 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 California flag specification

The California flag is set out in California Government Code Section 420, one of the most precise flag statutes in the country. It is two thirds as tall as it is long, with a red stripe along the bottom exactly one sixth of the height, a grizzly bear walking left across a green grass plot of twelve tufts and measuring two thirds of the flag’s height from nose to hind paw, one red five-pointed star in the upper hoist corner, and the words California Republic in condensed gothic capitals between the grass and the stripe.

Adopted in 1911 and standardized to its current form in 1953; it derives from the original Bear Flag raised at Sonoma during the Bear Flag Revolt of 1846, when a short-lived republic declared independence from Mexico and lasted twenty five days; the design is credited to William Todd, a nephew of Mary Todd Lincoln, who painted the original at Sonoma.

California is precise about proportion. Government Code Section 420 makes the flag two thirds as tall as it is long, which is two to three, and a 4x6 foot flag, an 8x12 foot flag, a 10x15 foot flag and a 12x18 foot flag all match it exactly. A 3x5 foot flag is a three to five ratio and is therefore slightly deeper than the statute describes, which is true of almost every 3x5 foot state flag sold in the country.

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

California Government Code Section 420 reads:

The Bear Flag is the State Flag of California. As viewed with the hoist end of the flag to the left of the observer there appears in the upper left-hand corner of a white field a five-pointed red star with one point vertically upward and in the middle of the white field a brown grizzly bear walking toward the left with all four paws on a green grass plot, with head and eye turned slightly toward the observer; a red stripe forms the length of the flag at the bottom, and between the grass plot and the red stripe appear the words CALIFORNIA REPUBLIC. Dimensions, excluding heading and unfinished flag ends: The hoist or flag width is two-thirds of the fly or flag length; the red stripe width is one-sixth of the hoist width. The state official flag hoist widths shall be two, three, four, five, six and eight feet.

The section continues with the proportions of the star, bear, grass plot and lettering, then the Textile Color Card Association references: White cable 70001, Old Glory red 70180, Irish Green 70168, Maple Sugar brown 70129, Seal dark brown 70108. The bear illustration itself appears only in the printed Statutes of 1953, chapter 1140.

This is what we actually make, not a stand-in for it.

What is on it and what it means

The bear is a California grizzly, a subspecies now extinct. The last one held in captivity, a bear named Monarch, was the model used when the flag was standardized. The star recalls the lone star of the 1836 California revolt. The original 1846 flag was destroyed in the San Francisco fire of 1906.

What most listings get wrong

Three errors are repeated constantly by other retailers and by general reference sites. The bear walks on all fours; it does not stand upright. The words California Republic sit below the bear, not above it. And the word Eureka belongs to the state seal, not to the flag, so any California flag carrying it is wrong.

Where the California flag flies

The Superflag, five hundred and five by two hundred and twenty five feet and about three thousand pounds, was made for Thomas Demski of Long Beach and was recognized by Guinness as the world's largest flag in the 1994 and 1995 editions. Its 1996 unfurling at Hoover Dam made it the largest flag flown. It no longer holds the world title but is still cited as the largest American flag. Calipatria in Imperial County has a one hundred and eighty four foot municipal flagpole so the flag flies at sea level in a town one hundred and eighty four feet below it. Dorris is documented as having one of the tallest United States flagpoles.

Fly it on California’s birthday

California became the 31st state on September 9, 1850. 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 California flag has an official reason to go up.

California Admission Day is September 9, a legal observance, and some cities close offices for it.

Have it on hand before the date arrives and it is on the flagpole in time. The full state-by-state list is on our state birthdays page.

Nylon or polyester in California

Nylon in the mild sheltered coastal valley metros, the Los Angeles basin, San Diego, San Jose and Sacramento. Polyester on the immediate coast for salt, in the high wind passes at San Gorgonio and Altamont, and in the high ultraviolet desert at Palm Springs and the Bakersfield edge.

For scale, the National Weather Service ultraviolet index forecast for Los Angeles on July 23, 2026 was 11 at solar noon, in the extreme band. That is the sun this flag has to survive.

On an exposed site from the list above, a hundred and fifty square feet makes nylon a non-starter. Check the flagpole and truck rating regardless of which material you order.

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.

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.

The benchmark institutions generally lean on comes from the American Legion: the federal government's own expectation is about ninety days for a daily sunrise-to-sunset flag, and roughly a quarter of that flying around the clock. Retailers report three to six months for nylon flown daily, four to eight months for polyester, and one to three years for occasional flying. Treat those as working estimates rather than a warranty, since exposure can shift them a great deal.

How the 10x15 Feet is built

Six rows at the fly end, zig zag stitched corners: at this area the wave traveling out to the tip moves fast enough that corner seams are the first place wind tests the flag.

The arithmetic behind that: 150 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.

Before it shows up, plan the handling — two people who know what they are doing, calm weather, halyard ready. A hundred and fifty square feet is not something to improvise.

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. Two plated steel thimbles finish a nylon rope sewn the length of the heading. At a hundred and fifty square feet, a grommet alone has no chance of holding the full load, which is why only one reinforced grommet remains, at the center of the heading, as a secondary attachment point.

This is commercial grade nylon: light enough to fly in a light wind, quick to shed water instead of holding it, and fast to dry, which matters because a waterlogged flag is a heavier flag putting more strain on its seams. UV resistant, field tested ink is what fights the sun, which is the real driver of color loss over time.

Why this flag is harder to make than most

A detailed bear silhouette, a twelve-tuft grass plot, lettering and a star, and a statute that fixes proportions precisely enough that a sloppy reproduction is visibly wrong.

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 California flag placed 13, at 7.00 out of 10.

Will it fit my flagpole?

It suits an in-ground flagpole of fifty to sixty feet, with a truck and halyard rated for the load.

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

A hundred and fifty square feet can load a flagpole past what it was engineered for. Confirm the flagpole and truck rating before ordering this size — an oversized flag on an undersized pole damages the pole first, the flag second.

Which size do I need?

One rule sits under both tables: the flag should run about a quarter to a third the height of the flagpole. On the border between two rows, the smaller flag flies more and lasts longer; the larger one is the one you can see from the road.

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

The proportion still applies past a hundred feet, but the decision changes character: the flagpole, the truck, the halyard, the foundation and the wind load stop being separate line items and become one engineered whole, and ordering a flag without confirming the flagpole rating puts the flagpole at risk first. A few famous flags fly deliberately larger than the rule suggests, and all of them do it with engineering behind the choice.

What is on the website is not the limit of what we carry. Any size in the tables above can be ordered, listed or not.

About the back of the flag

A single sided printed flag shows its design correctly on one face and reversed on the other. That is expected, and it describes almost every flag flying in the United States. A flag readable on both sides is built as two layers sewn around a liner, roughly double the cost and double the weight of a single sided flag. Unless a state’s law requires double sided, single sided remains the standard choice.

Flying it with the United States flag

Governing this is Title 4, Section 7 of the United States Flag Code, which keeps the United States flag in the position of honor: never below another flag, never to the right of one at the same level, meaning never right of the viewer’s left. Two flagpoles at equal height put the United States flag at the viewer’s left with equal-sized flags; unequal heights put it on the taller pole; a single flagpole with two flags carries it at the top. No penalty attaches for private citizens under the Code, but it is what institutions follow as standard practice.

Buy two and they both last longer

Rotate two flags on a monthly cycle and they will outlast three flags flown until they fail, because the fabric gets a rest and the fly end is not taking the same beating in the same spot every day. Bring it down before severe weather; one real windstorm can do more damage overnight than six ordinary months. Check the fly end, not the middle — a few minutes of stitching at the first sign of fraying buys another season.
