Colorado 12x18 Feet Nylon State Flag Made in USA

Large civic sites, memorial grounds and highway locations fly the 12x18 foot flag for the same reason: two hundred and sixteen square feet is visible from a long way off, which is the point of it.

This is the Colorado state flag at 12x18 Feet (216 square feet) in nylon, made in the United States and finished with a sewn rope and plated steel thimbles.

Built to the Colorado flag specification

The Colorado flag is set out in the Colorado Revised Statutes provisions on the state flag. It is three horizontal stripes, blue over white over blue, with a red circular letter C filled with a gold disk.

Designed by Andrew Carlisle Carson and adopted June 5, 1911, replacing an unused 1907 banner; colors were standardized to match the United States flag on February 28, 1929 and the letter size and position fixed March 31, 1964.

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.

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

Colorado Revised Statutes Section 24-80-904 reads:

A state flag is hereby adopted to be used on all occasions when the state is officially and publicly represented, with the privilege of use by all citizens upon such occasions as they may deem fitting and appropriate. The flag shall consist of three alternate stripes to be of equal width and at right angles to the staff, the two outer stripes to be blue of the same color as in the blue field of the national flag and the middle stripe to be white, the proportion of the flag being a width of two-thirds of its length. At a distance from the staff end of the flag of one-fifth of the total length of the flag there shall be a circular red C, of the same color as the red in the national flag of the United States. The diameter of the letter shall be two-thirds of the width of the flag. The inner line of the opening of the letter C shall be three-fourths of the width of its body or bar, and the outer line of the opening shall be double the length of the inner line thereof. Completely filling the open space inside the letter C shall be a golden disk; attached to the flag shall be a cord of gold and silver intertwined, with tassels one of gold and one of silver.

You do not have to take our word for any of that. Read Colorado Revised Statutes Section 24-80-904 in full at Justia, and check what we sell against it.

This is the actual flag we manufacture, not an approximation.

What is on it and what it means

Blue is the sky. Gold is sunshine and mining. White is the snow-capped Rockies and silver. Red is the ruddy earth. The letter C carries three meanings at once, Colorado, Centennial and Columbine.

What most listings get wrong

The designer is routinely named Andrew Carlisle Johnson. His surname was Carson. And the exact shade of gold is not fixed by statute, which is why the disk legally differs between manufacturers.

Where the Colorado flag flies

The Department of Personnel and Administration runs the Ceremonial Flag Request Program. The flag is flown at the State Capitol in Denver, folded in the traditional thirteen fold style, and returned with a certificate of authenticity carrying the date. Colorado residents only. State flags are offered in nylon and bunting, United States flags the same.

Time Plumbing, Heating and Electric in Denver near Sixth Avenue and Interstate 25, a flagpole reported at about a hundred and fifty four feet. There is a source conflict on the flag size. Denverite reported forty by eighty feet, the owner's own site says thirty by sixty, likely different flags over time. Denverite also reported that the town of Swink subsequently built a taller pole, so the record may be superseded.

Fly it on Colorado’s birthday

Colorado became the 38th state on August 1, 1876. 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 Colorado flag has an official reason to go up.

Colorado Day is August 1, a state observance on which the state parks offer free admission.

Order ahead and this flag is ready for the day. The complete list of state birthdays lives on our state birthdays page.

Nylon or polyester in Colorado

Polyester on the Front Range and plains at Denver, Colorado Springs, Fort Collins and Pueblo, for chinook and downslope windstorms and high altitude ultraviolet. Nylon only in sheltered mountain valleys.

This is installation-flag territory at two hundred and sixteen square feet. The exposed sites above that need polyester need it unconditionally, with a flagpole engineered for the load.

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.

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 12x18 Feet is built

Six rows of lock stitching on the fly end and zig zag stitched corners. Everything about the construction at this size exists to manage a load that would destroy a house flag in an afternoon.

Here is the arithmetic: 216 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 hundred and sixteen square feet is a scheduled operation, not an errand. Raise it and lower it with the site in mind, and never on a day the wind is already up.

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. The heading carries a nylon rope its full length, finished with two plated steel thimbles, so the load spreads across the whole hoist rather than concentrating anywhere.

Commercial grade nylon is the material in this flag. Light enough to catch a gentle breeze, it sheds water rather than holding onto it and dries fast, which keeps a flag from staying heavy and stressing its seams. The ink is UV resistant and field tested, since sun exposure is what determines how long the color lasts.

A design that reproduces cleanly

Four colors and one letter. The only real variable is the gold, which the statute leaves open.

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 Colorado flag placed 16, at 6.83 out of 10.

Will it fit my flagpole?

Sixty to eighty feet of in-ground flagpole, with hardware rated for it, is the right fit for this size.

Questions about the 12x18 Feet

What size flagpole for a 12x18 foot flag? Sixty to eighty feet with hardware engineered for two hundred and sixteen square feet of load.

Who buys a 12x18 foot state flag? Civic sites, memorial grounds, highway frontages and campuses, anywhere the flag is meant to be seen from a long way off.

Does a flag this size need special care? It needs a rotation, hardware checks, and taking down in severe weather. Flown properly it lasts. Flown carelessly it does not last a season.

This size is a commitment

A flag this large is a scheduled maintenance item rather than something you put up and forget. It wants a rotation, it wants the hardware checked, and it wants taking down in severe weather. Flown properly it lasts. Flown carelessly it does not last a season.

Which size do I need?

The proportion that makes both tables work is simple: length equal to roughly a quarter to a third of the flagpole’s height. Sitting between two sizes is common, and the choice there is really a trade between a flag that flies often and one that is seen from a distance.

• 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

• 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.

We carry the full range whether or not every size appears on this website. If the size you need is not listed, we can still supply it.

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

This is governed by the United States Flag Code, Title 4, Section 7: the United States flag always outranks every other flag in position, never displayed below it or to its right at the same level — right from the viewer’s side, that is. Two flagpoles of equal height place the United States flag at the viewer’s left with both flags the same size; if the poles differ in height, it goes on the taller pole; on one pole flying two flags, it sits at the top. The Flag Code carries no penalty for private citizens, but institutions treat it as the standard.

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.
