Which heating mat for a 10 gallon tank?

I was wondering what wattage heating mat I should get. I have a 10 gallon tank and was debating on the 5 gallon: 4 Watts or the 10-20 gallon: 8 watts.
I know it has to heat half the tank and I plan on using paper towels as substrate for a baby leopard gecko.
Doing my research before hand!:main_robin:

Look at the measurement of the under tank heating pads, they should cover 1/3 of the tank, no larger than 1/2. So chances are you need the 5 gallon one, but like I said, you'll want to make sure they fit properly and they cover 1/3 of the tank.
