An adult bald eagle can have a wingspan of up to about 6 feet for males and 8 feet for females, according to the U.S. Fish & Wildlife Service (USFWS). That is a wingtip-to-wingtip measurement—not the bird's body length or standing height.
USFWS gives a general adult body length of about 30–40 inches and weight of 8–14 pounds. Individual size varies with sex and region. Females are larger than males.
| Reference | Wingspan | Approximate metric length |
|---|---|---|
| Male, upper reference from USFWS | Up to 6 ft (72 in) | Up to 1.83 m |
| General adult reference from USFWS | About 7–8 ft (84–96 in) | About 2.13–2.44 m |
| Female, upper reference from USFWS | Up to 8 ft (96 in) | Up to 2.44 m |
These are species references, not a promise that every bird reaches the top of its range. The Cornell Lab of Ornithology lists 80.3 inches (about 6 ft 8 in) as a bald eagle wingspan measurement. It is a useful size reference; it should not be read as the exact wingspan of every eagle or a universal average.
“Wingspan” means the distance between the tips of the outstretched wings. It does not describe how long the eagle is from bill to tail.
A simple reference is to picture a 6-foot-wide line stretched across a wall. A bald eagle's wingspan can be around that width or extend toward 8 feet, depending on the bird.

Length comparison only, not a drawing of a bird or a scale image.
A 6-foot-tall person is a convenient hypothetical reference: a large female eagle's 8-foot wingspan is 2 feet wider than that person's height. The measurements point in different directions—one is horizontal wingtip to wingtip; the other is vertical standing height.
| Measurement | Reference size |
|---|---|
| Body length, bill to tail | About 30–40 in (2.5–3.3 ft; 76–102 cm) |
| Weight, general adult reference | About 8–14 lb (3.6–6.4 kg) |
| Wingspan | Common references extend from about 6 ft to 8 ft |
USFWS describes males as smaller, with wingspans up to 6 feet and weights up to 10 pounds; females may reach 8 feet across and 14 pounds. The Smithsonian's National Zoo gives a broader weight range of 6.5–14 pounds. These ranges reflect variation among birds, not a single standard-size specimen.
A bald eagle does not have one fixed “standing height” used in the same way as a person's height. Bird guides commonly report body length, measured from the bill to the tail, and wingspan separately. For a clear size comparison, use the measurement that matches the question.
Use a hypothetical 6-foot person as a simple reference:
A person standing upright and a bird with spread wings have different shapes. The comparison helps visualize a length; it does not mean an eagle stands as tall as a person or has a person-sized body.
Male bald eagles are generally smaller than females, and eagles in northern parts of their range tend to be larger than those in southern areas, according to USFWS.
That is why reference pages may give slightly different ranges or one rounded “typical” number. Check whether a figure describes a male, female, a particular region, or a general adult reference. A wingspan is also measured only when both wings are fully extended, while body length is a separate measurement.
The USFWS reference gives up to 6 feet for males and up to 8 feet for females. General adult references often describe a span around 7–8 feet.
There is no one exact span for every eagle. Cornell Lab lists 80.3 inches, about 6 feet 8 inches, as a species measurement; sex and regional variation affect individual birds.
USFWS gives a general adult body length of about 30–40 inches, or roughly 2½–3⅓ feet.
USFWS lists males up to about 10 pounds and females up to about 14 pounds. The bird's sex and region matter, so 14 pounds is not a typical weight for every eagle.
A single standard standing-height figure is not commonly used in the cited references. They report body length from bill to tail, wingspan and weight. These answer different size questions.
No. “Eagle” covers many species. The dimensions here refer specifically to the bald eagle.
Measurements are rounded for readability and vary among sources and individual birds. The human-size example is an arithmetic comparison, not an average-person statistic. The diagram is conceptual and not to scale.
