There is a lot of controversy over poodle sizes. The AKC Poodle Standard is pretty clear on the subject. The confusion starts when someone is describing a teacup or tiny toy poodle.

Teacups, pocket poodles and tiny toys are all toy poodles. They are just smaller, there is no separate classification for them. American Kennel Club recognize Standard, Miniature, and Toy Poodle sizes only

Here is the general rule.

Teacup, Tiny Toy and Pocket Poodle - Teacup is a term breeders use to describe very small poodles, which usually weigh under four pounds. American Kennel Club recognize Standard, Miniature, and Toy Poodle sizes only. Any other size description is strictly breeder terminology. Teacups average from 2 1/2 to 3 1/2 pounds and 8 inches at the shoulder or less when full grown. Tiny Toys average between 4 pounds and 6 pounds when fully grown and stand between 8 to 9 inches. I might point out that some poodles will be short (7 inches) and weigh 6 pounds and others will stand 9 inches but only weigh 3 pounds. They do vary.

Standard: Over 15 inches in height at the highest point of the shoulders.

Miniature: Over 10 inches and up to 15 inches at the highest point of the shoulders.

Toy: 10 inches or less at the highest point of the shoulders.
