Alpaca vs. llama: what's the difference?
By the Alpaca Atlas team · Updated · Data as of September 27, 2026, rebuilt with every catalog update · Last reviewed September 28, 2026
Alpacas and llamas are both domesticated South American camelids. Alpacas are much smaller and are raised mainly for their fleece. Llamas are bigger and have long been used as pack animals. Alpaca fleece is soft and almost free of coarse guard hair, while a llama's coat mixes a fine undercoat with coarser hair. In the knitwear we track, llama is rare: only 2 of the 4,514 alpaca pieces we track mention llama in the name or fiber, and none of them states a fiber breakdown.
Side by side
Heights are measured differently: for alpacas the sources give height at the shoulder, for llamas height to the top of the head.
| Alpaca | Llama | |
|---|---|---|
| Weight | 100–200 lb (45–90 kg) | 287–600 lb (130–272 kg) |
| Height | 32–40 in (0.8–1.1 m) at the shoulder | 5 ft 7 in–5 ft 11 in (1.7–1.8 m) to the top of the head |
| Ears | Large and pointed | Long, curved inward (“banana” shaped) |
| Wild ancestor | Vicuña | Guanaco |
| Raised mainly for | Fleece | Carrying loads; also fiber and meat |
| Coat | Soft fleece, virtually free of guard hair | Fine undercoat plus coarser outer guard hair |
Size and looks
The Smithsonian's National Zoo calls alpacas the smallest of the domesticated camelids: adults usually weigh 100 to 200 pounds and stand 32 to 40 inches at the shoulder. Wikipedia gives a full-grown llama 287 to 600 pounds and 5 ft 7 in to 5 ft 11 in to the top of the head.
The ears are the quickest tell. Alpacas have large, pointed ears. Llama ears are long and curve inward, a shape often called “banana” ears. Wikipedia also lists the llama's longer head among the differences.
Where they come from
Both were domesticated in the Andes from wild relatives. DNA work published in 2001 (Kadwell et al., Proceedings of the Royal Society B) showed the alpaca descends from the vicuña and the llama from the guanaco. Both wild species still live in the Andes.
Alpacas were traditionally herded in the Andes of southern Peru, western Bolivia, Ecuador and northern Chile, at about 11,000 to 16,000 feet. According to Wikipedia, Peru has more than half of the world's alpacas.
All four South American camelids (alpaca, llama, vicuña and guanaco) can crossbreed.
What each is raised for
Alpacas are bred mainly for their fleece. They're shorn about once a year; the Smithsonian's National Zoo puts it at about 8 pounds of fiber a year for males and 5 for females.
Llamas have long been pack animals: Wikipedia says they can carry about 25 to 30% of their body weight for 5 to 8 miles. In North America they're also used as livestock guardians for sheep.
Alpaca fiber vs. llama fiber
Alpaca fleece is soft and virtually free of guard hair, the coarse outer hair that can feel prickly. Most alpacas are Huacaya, with crimpy, fluffy fleece; the rarer Suri has long, silky locks.
Llamas have a fine undercoat that can be used for garments, but the coarser outer guard hair goes into rugs, wall hangings and lead ropes.
In the sweaters, scarves and blankets we track, llama is rare: only 2 of the 4,514 alpaca pieces we track mention llama in the name or fiber, and none of them states a fiber breakdown. Softness depends on the grade, not only the animal: see alpaca grades explained.

Frequently asked questions
- Which is bigger, an alpaca or a llama?
- The llama. Adult alpacas usually weigh 100 to 200 pounds; a full-grown llama can weigh 287 to 600 pounds.
- How can you tell an alpaca from a llama?
- Look at the size and the ears. Alpacas are smaller, with pointed ears. Llamas are much larger, with long ears that curve inward.
- Is llama wool the same as alpaca wool?
- No. Alpaca fleece is almost free of coarse guard hair. Llamas have a fine undercoat plus coarser guard hair, which is used for rugs and ropes rather than clothing.
- Can alpacas and llamas breed?
- Yes. All four South American camelids, alpaca, llama, vicuña and guanaco, can crossbreed.
- Do alpacas spit?
- Rarely at people. The Smithsonian's National Zoo says alpacas rarely spit at people unless frightened or abused, but they use it with each other to register a complaint.
