Flag Size Chart

Flag sizes are specified in width x height (W x H) for rectangular flags, and in total pole height for feather flags, sail signs, and swooper-style display flags. The standard outdoor flag for residential and commercial use is 3′ x 5′. The standard flagpole-to-flag ratio is one-quarter to one-third the pole height. A 20-foot pole flies a 3′ x 5′ flag, a 30-foot pole flies a 5′ x 8′ flag. For branded promotional flags, size is determined by the display context: event, tradeshow, outdoor roadside, or handheld use.

TLDR: Standard outdoor flag: 3′ x 5′. Standard stick flag: 4″ x 6″ or 12″ x 18″. Feather flag kits: 8′, 11′, 14′, 17′ total pole height. Sail signs: 6.5′ to 22.5′. Nylon rectangular flags in the MFG Merch catalog range from 2′ x 3′ to 8′ x 12′. Flag size and flagpole height must be matched. An oversized flag on a short pole droops and tangles; an undersized flag on a tall pole is barely visible.

For branded flag programs, flag type determines the print method, the visibility distance, and the installation hardware required. Dye sublimation on polyester is the standard for feather flags, sail signs, and full-color outdoor flags. Screen printing and direct digital print are used for smaller stick flags and hand flags. Single-sided flags show a mirror image through the reverse. Double-sided flags use a block-out liner between two layers for visibility from both sides without bleed-through.

Key Takeaways

• Flag size = width x height (W x H): Flag dimensions are always stated width first, then height. A 3′ x 5′ flag is 3 feet wide (the hoist, attached to the pole) and 5 feet long (the fly, extending away from the pole). This convention is the same for all rectangular flag formats.
• Flagpole ratio: flag should be 1/4 to 1/3 of pole height: A 20-foot pole should fly a 3′ x 5′ flag. A 30-foot pole should fly a 5′ x 8′ flag. A flag smaller than 1/4 of the pole height disappears visually at distance. A flag larger than 1/3 of the pole height tangles and wears out faster.
• Feather and sail flags are measured by total system height: An “8-foot feather flag kit” has an 8-foot total height including the pole and ground spike. The flag fabric itself is shorter than 8 feet because the hardware accounts for the remaining height above the fabric panel.
• Single-sided vs. double-sided affects visibility and cost: Single-sided flags print on one layer. The reverse shows a mirror image through the fabric. Double-sided flags use two printed layers sewn together with a block-out liner between them, so the artwork is clear and correct on both sides. Double-sided costs significantly more but is required for flags visible from multiple directions simultaneously.
• Material determines outdoor durability: 200 denier nylon is the standard for outdoor rectangular flags: it dries quickly, resists UV fading, and performs in wind. Super poly knit fabric is the standard for feather flags and sail signs because it moves well in light wind. 100 denier polyester is used for lightweight hand flags and stick flags.

Standard Flag Sizes by Flagpole Height

The flag-to-pole ratio ensures the flag is visible from a distance without tangling or overpowering the pole structure. The table below reflects the standard US flag sizing recommendations for in-ground residential and commercial flagpoles.

Flag Size Chart by Flag Category

The MFG Merch flag catalog covers nine distinct flag categories, each with different size conventions, materials, mounting methods, and use cases.

Rectangular nylon flags

Rectangular nylon flags are the standard format for outdoor branded flags, patriotic flags, and organizational display. All use 200 denier nylon as the base material. Sizes available in the catalog range from 2′ x 3′ to 8′ x 12′.

Feather flags and sail signs

Feather flags (also called blade flags, swooper flags, flutter flags, and beach flags) and sail signs are shaped display flags mounted on flexible poles with ground spikes or cross bases. They are measured by total system height (pole + spike + flag). The flag fabric panel is shorter than the total system height. For reference, an 11-foot feather flag kit typically has a fabric panel of approximately 2.5 feet wide x 9–10 feet tall.

Stick Flag and Hand Flag Size Chart

Stick flags and hand flags are the smallest category in the flag catalog. They are sized by the flag panel dimensions (W x H), not by the pole length. Pole length is typically stated separately and is included with the product. Standard stick flag sizes range from 4″ x 6″ (the most common handheld size for events) to 12″ x 18″ (the standard larger stick flag for stadiums and parades).

Pennant Flag Sizes

Pennant flags are triangular or custom-shaped flags mounted on a pole or hanging flat on a wall. The catalog includes two standard nylon pennant sizes plus a felt pennant format.

Specialty Flag Sizes

Several catalog flag types use unique size conventions based on their application context.

Golf flags

Golf flags are sized for standard golf hole pins. The standard golf flag size is 14″ x 20″, which fits a standard golf pin (21mm diameter) with a plastic or metal mounting tube insert. The catalog also offers golf flags at 14″ x 20″ with a 6-foot fiberglass pole (part of the Sports Fan All-in-One Kit) for display away from the course. Nylon golf flags with a tube stitched into the flag are available in single-sided and double-sided formats.

Garden flags

Garden flags display on a two-prong ground stake hardware frame. The standard garden flag size is 12″ x 18″, which fits standard garden flag hardware. The kit includes the flag and a metal pole with a 2-prong ground stake base. Available in single-sided and double-sided formats in 200 denier nylon and in polyester for the DisplaySplash format with a 39-inch iron pole.

Guidon flags

Guidon flags have a distinctive swallow-tail fly end (notched at the right edge). They are available in two catalog sizes: 16″ x 24″ (standard guidon) and 20″ x 27.75″ (military-sized guidon). Both are constructed of 200 denier nylon with canvas heading, brass grommets, and swallow-tail shaping. A larger 3′ x 5′ polyester guidon with double-sided dye sublimation is also available.

Spirit flags

Spirit flags are large waving flags intended for stadium, pep rally, and athletic use. They have a 3-inch pole sleeve closed at the top and a leather tab at the bottom for zip-tying to a pole. Available in 3′ x 5′, 4′ x 6′, and 5′ x 8′, both single-sided and double-sided.

Body flags

Body flags are worn as a cape. The USA and Pride body flags are constructed of flame-retardant 100 denier polyester. No specific dimensions are listed in the catalog description; they are sized to drape across an adult’s back and shoulders when worn.

Car flags

Car flags mount in the car window with a clip and 1.5-inch pole sleeve. The Sports Fan All-in-One Kit includes a 12″ x 16″ poly car flag with a 17″ flex pole. A separate car flag kit is also available in polyester knit with dye sublimation printing.

Micro and mini sail signs

Micro teardrop sail signs at 17.5″ tall are desk and table display formats. The entire kit weighs under 4 ounces and uses a shiny aluminum base. Mini teardrop sail signs come in suction cup base and clip-on base versions for vehicle and retail display. Burgee flags at 12″ x 18″ are designed for nautical and marina use.

Flag Print Methods and Artwork Requirements

The print method is determined by the flag material and size. All feather flags, sail signs, and rectangular flags in the catalog use dye sublimation on polyester fabric as the standard process. Dye sublimation embeds the ink into the fiber rather than sitting on the surface, which produces UV-resistant color that does not crack, peel, or fade as quickly as surface printing under outdoor conditions.

Flag Warranty by Type

Outdoor flag warranty periods vary by construction and material. Understanding warranty coverage is important for programs where flags will be used continuously or in harsh weather.

FAQ

What is the standard flag size?

The standard outdoor flag size for residential and small commercial use is 3′ x 5′ (3 feet wide x 5 feet long). This size is compatible with most residential flagpoles of 15–25 feet and is the most widely stocked size across all flag materials and print methods in the MFG Merch catalog. For flagpoles below 15 feet, a 2′ x 3′ flag provides a proportional display. For poles above 25 feet, step up to 4′ x 6′ or 5′ x 8′.

What is the difference between a feather flag and a sail sign?

Feather flags and sail signs are both pole-mounted display flags with curved shapes, but they differ in shape profile and pole construction. Feather flags (also called blade, swooper, or flutter flags) have a characteristic pointed top and a curved outer edge that produces a flowing shape in the wind. Sail signs include multiple shape profiles: razor (narrow and angular), teardrop (rounded top, pointed bottom), blade (wider, more rectangular), and sabre (swept-back curved profile). All use dye sublimation on poly knit fabric and are sized by total system height including the pole and base hardware.

What size flag do I need for my flagpole?

Use the ratio of one-quarter to one-third of the pole height as the flag length. A 20-foot pole flies a 3′ x 5′ flag (5 feet is one-quarter of 20 feet). A 30-foot pole flies a 5′ x 8′ flag (8 feet is approximately one-quarter of 30 feet). Going smaller than 1/4 of the pole height makes the flag appear insignificant. Going larger than 1/3 causes the flag to droop, tangle, and wear out faster because it is too heavy and catches too much wind for the pole’s flex rating.

What is the difference between single-sided and double-sided flags?

A single-sided flag is printed on one layer of fabric. The ink penetrates partially through the fabric, so a mirror image of the design is visible when looking at the back of the flag. This is the standard and most cost-effective format. A double-sided flag is constructed from two separately printed layers of fabric sewn together with a block-out liner between them. The design reads correctly from both sides with no bleed-through. Double-sided flags are required for applications where the flag is visible from two directions simultaneously, such as road-mounted flags or flags displayed in the center of a space rather than against a wall.

What artwork file format is needed for flag printing?

For dye sublimation on feather flags and sail signs, high-resolution raster files (at least 150 DPI at final output size) or vector files (AI, EPS, PDF) are both acceptable. Vector is preferred for logos with clean edges and solid colors. For rectangular nylon flags with digital direct printing, the same standards apply. For stick flags with screen printing, vector artwork is required because screen printing cannot reproduce photographic gradients. All flag artwork should be built to the specific template provided for the flag shape and size, because the template accounts for the flag’s pole pocket, hem allowances, and any trim areas that cannot carry printed artwork.
