Size class
Also called: giant koi, large koi
Koi over roughly 24 inches (60cm+), typically 4+ years old from strong Japanese bloodlines — Chagoi, and big-bodied Kohaku/Sanke lines like Sakai and Momotaro, reach jumbo size most reliably. Expect four-figure prices and freight shipping.
| Grade | Typical price (6–10″ unless noted) |
|---|---|
| Pond / garden quality | $800 – $5,400 |
| High grade / import | up to $10,000 |
| Show grade | $15,000+ |
Size, age, variety, and bloodline all multiply price; champion-line jumbos reach six figures at auction.
Size, body conformation, and breeder line move prices more than variety alone — see the full koi price guide.
