"Is it that big?" As far as I am concerned, this is grammatically OK.
Can I write it(above context) in another way to have the same meaning? For eg: Is it such a big? or Is it that much bigger? etc.
In my original context, does "that" always refer to only size? not amount, degree and limit? If it("that') refers to any except size, please kindly provide some examples.
You can use "Is it that much bigger?" as long as whatever it refers back to is something which is appreciably bigger than something else.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Let me make an inquiry. Of both of you, one accepts my one suggestion (Is it that much bigger?) but another doesn't. To be honest I am confused. I known there is at least a slight difference in accent and vocabulary used in English in every English country. Is there difference in grammar too?

Okay! now I got. I can use both according to contexts. Clear!
I suggested that you can't use those other sentences to mean "Is it that big?".
ems suggested that under certain circumstances you can use the sentence "Is it that much bigger?"
They don't mean the same thing, but there are some circumstances in which either sentence would be an acceptable answer.
I think the important thing is to try to understand the meaning of the sentence. Once one knows the meaning of sentence A and the meaning of sentence B, one can usually work out for oneself whether sentence A means the same as sentence B, and in which contexts this holds true, and in which it doesn't.
