Golden Orb spider

This golden orb spider is massive! It clearly located it's web in a good position. How much bigger will it get, I wonder? Imagine if it just grew and grew and grew ...
C has been in bed with 2 days with the flu. Poor kid is so run down at the moment. We elected not to let her have a blood transfusion at surgery but she's still so pale and depleted. Luckily she has the warmest room in the house and is nowhere near this spider!!
