Flagpole Size Guide

Choosing the right flag size for your flagpole is essential for both appearance and flag longevity. A flag that is too large will be difficult to fly and will wear out faster; one that is too small will look lost on a tall pole. The general guideline is that the flag's fly length (the longer dimension) should be one-quarter to one-third of the flagpole height.

Flagpole HeightRecommended Flag SizeUse Case
6 ft (wall-mount)2×3 ftPorch, apartment, small outdoor staff
15 ft3×5 ftResidential — most common choice
20 ft3×5 ft or 4×6 ftStandard residential, small business
25 ft4×6 ftResidential, small commercial
30 ft5×8 ftCommercial, government buildings
40 ft6×10 ftLarge commercial, municipal buildings
50 ft8×12 ftState buildings, large commercial
60 ft10×15 ft or 10×19 ftFederal buildings, stadiums
80 ft15×25 ftLandmark sites, large federal facilities
100 ft+20×30 ft or 30×60 ftMega flagpoles, national landmarks
Pro Tip: In high-wind areas or coastal locations, choose a flag one size smaller than the chart recommends. A smaller flag in high winds will fly better, look fuller, and last significantly longer than an oversized flag that takes constant beating.

Official Proportions & Specifications

The official proportions of the American flag are established by Executive Order 10834, signed by President Eisenhower on August 21, 1959, which also set the arrangement of the 50 stars. These specifications are used for government procurement (federal, military, and government buildings) under standards like DLA MIL-F-3724.

Note for Buyers: Most commercial flags — including quality Made-in-USA products — use the popular 3×5 ft and 4×6 ft sizes, which have a fly-to-hoist ratio of approximately 1.667:1, not the official 1.9:1. The 1.9:1 ratio is primarily used for government-specification (gov-spec) flags purchased by federal agencies and the military. Both look correct when flown; the ratio difference is only apparent on close inspection.

Star Arrangement

The 50 stars are arranged in alternating rows: 6 rows of 6 stars and 4 rows of 5 stars, for a total of 50 stars. Stars point upward (one point directly up). The arrangement creates a clean, symmetrical field when viewed from a distance.

Size by Use Case

Residential Flagpole

The 3×5 foot flag is the standard choice for most residential flagpoles up to 20 feet tall. It is the most widely available size, offered by every major manufacturer, and provides excellent visibility from the street. For a 25-foot pole or a prominent home display, the 4×6 foot flag offers a more commanding presence.

Porch or Bracket Mount

For wall-mounted brackets or porch staffs (typically 5–6 feet long), a 2×3 foot flag is the correct choice. It fills the staff without dragging on the ground or bunching when there is no wind.

Handheld & Parade Flags

Handheld flags for parades and events are typically 12×18 inches or smaller, mounted on a wooden or plastic stick. These are often made of lightweight printed nylon or paper and are intended for single-use occasions rather than extended outdoor display.

Indoor & Ceremonial Display

For indoor floor stands used in offices, courtrooms, or ceremony settings, a 3×5 foot or 4×6 foot flag is standard. Indoor ceremonial flags are typically made of cotton or rayon for a richer look and drape better on an indoor staff.

Commercial & Government Buildings

Commercial buildings and government facilities typically use flags sized 5×8 feet and larger, scaled to their pole height (see the flagpole guide above). Government-specification flags must meet federal procurement standards and be Made in the USA under the Berry Amendment.

Frequently Asked Questions

What size American flag for a 20-foot flagpole?
For a 20-foot flagpole, a 3×5 foot flag is the standard recommendation. For a more prominent residential display, a 4×6 foot flag works well. In high-wind areas, stick with the 3×5 foot to reduce wear on the flag and pole hardware.
What are the official proportions of the American flag?
Per Executive Order 10834 (1959), the official fly-to-hoist ratio is 1.9:1. A flag with a 3-foot hoist would have a 5.7-foot fly under this specification. Most commercial flags are sold in the popular 3×5 ratio (1.667:1), which is slightly different but acceptable for non-government use.
What is the most popular American flag size?
The 3×5 foot flag is by far the most popular size for residential use in the United States. It is the standard size offered by nearly every flag retailer and manufacturer, and is appropriate for most home flagpoles up to 25 feet tall.
How do I measure my flagpole to pick the right flag size?
Measure the total height of your flagpole from the base to the tip. The flag's fly (longest dimension) should be roughly one-quarter to one-third of the pole height. For a 20-foot pole: one-quarter is 5 feet (matching the 3×5 flag's fly length perfectly). For a 30-foot pole: one-quarter is 7.5 feet, suggesting a 5×8 flag.
