what is the inside hole dimensions not the outgide dimensions?

This seat opening measures 8" at the widest point and 12" at the longest point. Sincerely, Your American Standard Consumer Connection Team.

Will this fit American Standard model 4225A?

Hello, The 4225A is your tank number, so it would depend on the bowl you have. If you have a standard, elongated bowl, this seat will work. Thank you, Your Consumer Connections Team

Will this fit on a american standard with 6.0 lpf and 1.6 gpf ?

The numbers that you are providing are only the liters and gallons per flush of the toilet. That doesn't indicate what shape of bowl you have. This seat fits on a standard elongated toilet bowl. Sincerely, Your American Standard Consumer Connection Team

What is the length of the seat from the center of the bolt holes to the front edge of the seat?

About 18 1/2 inches. This fit all 3 of my toilets.
