Apparently a 747 needs about 7500ft, depends on elevation and model.

Those numbers are not etched in stone Stormer.
(I'll expand on this here.)
I'm not looking them up, but those figures would be based on a typical payload/aircraft weight scenario based on ISA conditions. (International Standard Atmosphere.) All aircraft are provided with with Take-Off performance charts with regards to Take-Off Distance (Ground Roll); and, Take-Off Distance, Ground Roll to 50' AGL. (About Ground Level.)
(+ charts for: climb-out; distance/fuel for climb; climb gradients, bla, bla, bla.)
That said, flight crews also need to consider:
For runways:
● Runway length;
● Runway surface contamination;
● Runway slope;
● Hard/soft runway;
● Wind speed and direction (including gusts);
Density Altitude:
● Heat/cold;
● Baro pressure;
● Humidity;
● Elevation
Or any combination thereof.
All the above conditions are still above and beyond any given payload.
