How are sprockets size?

What is roller diameter of sprocket?
The roller diameter is “nearest binary fraction” (32nd of an inch) to 5/8ths of the pitch; pin diameter is half of roller diameter. The width of the chain, for “standard” (0 series) chain, is the nearest binary fraction to 5/8ths of the pitch; for narrow chains (1 series) width is 41% of the pitch.

Are all bike chains the same size?
Chains can vary in side plate shape, sizing, and height. Differences can cause variations in shifting performance between brands and models. Additionally, chains will vary in the quality of steel used. Better chains that are more durable and longer lasting tend to have harder rivets.
