It will depend on how much information is being sent. It's not a fixed size. The only certain part is that there is an UDP header. If you want to see the packet you need to perform a capture. Is there any specific reason why you want to know the packet size?
To establish control over the largest Simple Network Management Protocol (SNMP) packet size permitted when the SNMP server is receiving a request or generating a reply, use the snmp-server packetsize command in global configuration mode. To restore the default value, use the no form of this command.
I agree with Daniel that rarely is the load imposed on the network by SNMP going to have noticeable impact. It is really not important what is the packet size and is more important how much information is being sent. And the major factor that determines this is how your NMS server is configured. Let us consider a somewhat extreme example in which the NMS is polling all devices every 10 seconds and is requesting all interface status, all memory status, contents of the entire routing table, and a copy of the configuration (all this information for every poll to every device every 10 seconds). If your NMS is configured in a more reasonable way then the load on the network will be reduced.

actually i want to enable SNMP for access switches about 100 unit. this is for NMS (non cisco). is it the SNMP packet will affect the network performance?
It might - it depends (i.e. how often you poll the device and what data you poll for). (Also, SNMP polling can add to the device's CPU loading.)
