Colorado 10x15 Feet Nylon State Flag Made in USA

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 Colorado 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 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.

This statute sets the design, the colors and the seal or emblem, without pinning down a size for an outdoor flag. That is how most states have written their flag laws, and it explains why every manufacturer uses the same standard sizes.

This flag reproduces the design faithfully, built to the standard outdoor sizes used across the industry and bought by the states themselves. The colors, the seal and the emblems are the part that has to be right on an outdoor flag, and they are right here.

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.

It is the real flag we produce, not a simplified version.

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.

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 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.

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.

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.

One more consideration, learned by most people only after a repeat purchase: a nylon flag moves in conditions where polyester hangs still. If the flag needs to actually be flying — a calm morning, a holiday, a funeral, a ceremony — that is an argument for nylon even on a site where polyester would technically outlast it. A flag that just hangs there has failed just as much as one that frays.

The number most institutions rely on traces to the American Legion, which reports a roughly ninety-day expectation from the federal government for a flag flown daily sunrise to sunset, and about a quarter of that flown around the clock. Retailer experience puts nylon at three to six months daily, polyester at four to eight, and an occasionally flown flag at one to three years. These figures are practical guidance, not a warranty, and exposure will move them considerably.

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.

This size needs a plan in place before delivery: two coordinated people, a calm day, and the halyard already sorted for a hundred and fifty square feet of flag.

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. 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.

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?

This size wants an in-ground flagpole between fifty and sixty feet, matched with hardware rated for its 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

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?

The rule that governs both tables is a length-to-height ratio of about one quarter to one third. Borderline cases favor the smaller size if you want it flying often and lasting, or the larger size if the point is to be seen from a distance.

• 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.

We supply the whole range shown above, whether or not a given size currently has its own listing on the site. Ask if you do not see it.

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

Title 4, Section 7 of the Flag Code is the source for this. The United States flag is never subordinate in position — nothing flies above it, and nothing takes its place at the viewer’s left when flags are level with each other. On matched flagpoles, the United States flag takes the viewer’s left and the flags should be sized the same; on unequal flagpoles, it goes on the taller one; and on a single pole flying two flags, it goes at the top. There is no penalty for civilians who do not follow the Code, but institutions treat it as the standard regardless.

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.
