What do you mean by "size"? If you mean it in the way as in C, the answer is no. It takes quite some bytes just to represent anything in Perl.

Here's a schematic view of an integer in Perl: 

      SvIV            xpviv 
    +--------+      +--------+
    | Any +--+----->| (PVX)  |
    +--------+      +--------+
    | RefCo  |      | (CUR)  |
    +--------+      +--------+
    | Fl  |T |      | (LEN)  |
    +--------+      +--------+
                    |  IVX   |
                    +--------+
All fields are 32 bits wide. Note that there are other ways integers can be stored in Perl, in might have been used as a float or a string; then the size will increase. But the minimum size is 28 bytes.
