Serama size & Lifespan compared to Japanese size & Lifespan?

[LordBantam]

If I'm correct both's average lifespan is seven years. But I'm not sure on size.

Plus I live in the suburbs so if there is a a better breed for me please inform me.

Thank you,
Elijah.

I've heard of some Seramas even living to 9 years. As for size, there are 4 sizes: micro, class A, class B, and class C. Here are the weights:

Roosters:
Micro up to 13 ounces
Class A under 13 ounces
Class B under 16 ounces
Class C under 19 ounces

Hens:
Micro up to 8 ounces
Class A under 12 ounces
Class B under 15 ounces
Class C under 19 ounces

Sometimes there will be Seramas that weigh more than class C's. They are considered class D and are culls (but any size would make a great pet!)
