4 feet + 3 feet as stated by op = 7 feet or 84".
2 metres = 78.75"
Difference = 5.25"
If concerned op can reduce the fence by trimming, but personally I would go with a standard panel. If somebody complains then I would trim the fence panel, but I doubt that will be necessary.
So your point is yes, I can't calculate the difference and yes, I shouldn't have bothered. Glad you cleared that up.
