Economy Exit Row seats downstairs on 747 LGW1 config

Hi all,
Flying to LV shortly and have selected exit row downstairs in Economy for outbound as the bubble ones had gone. I'm next to the window but have options available to change at the moment but from memory I think exit door slide bulge (sorry for description) encroaches into the leg room space but can't remember how much, can anyone help please ?
Just not sure if it would be a problem for me (5ft10) or should I change to an aisle seat instead.
Thanks for listening and would value any advice
