I think you mean the actual size, and in that case no it's not bigger. Inodes are a fixed size, usually 256 bytes, and a file strictly has one inode. The only growth happens in data blocks.

It's also worth looking at NTFS, where a file can have multiple records, the equivalent of inodes. But it uses the same logic for tiny files. If it doesn't fit inside the base record, it goes into a data block. Multiple records only show up for large amounts of metadata.
