That's 3.14″ of overhang total — about 1.57″ on each end so the seal grips properly.

The math, if you'd rather do it yourself
Each strip of tape needs to cover the full length of the box's seam, plus a bit of overhang on each end so the seal grips the side flaps instead of peeling up.
The rule of thumb: 3.14″ (8 cm) of total overhang — about 1.57″ on each end. Double it if you're sealing both the top and the bottom.
