How do pilots of big widebody planes know if their planes are lined up with runway when they take off?
On a fighter jet, you can look at your HUD and see if it the dots point out the end of the runway. How can you do this on passenger planes?

If you only look at the window, it looks differently depending on your head location.

Generally speaking, lining-up an airplane on a runway is a visual maneuver - No difference between line-up of a Piper Cub or a Boeing 747 - Yes, the compass is checked to verify alignment on the proper runway (QFU) - Adjustments to alignment are made with nose wheel steering (rudder pedal or tiller) - Above 60 knots or so, the rudder surface is effective - no need for steering -
Do not imagine your "flight sim game" to be same as a real airplane...! You evidently are NOT a pilot -
The centerline of the runway is clearly marked. By the time you get in the front seats of any airliner, you would have preformed thousands of takeoffs, every single one of them done by looking out the windscreen and visually tracking down the centerline.
Edit : Even in the largest "wide body" airliner, the pilot's position relative to the centerline does not vary much, at least laterally. You might be sitting higher off the ground, but the centerline is going to be within a few inches of being directly under your elbow. Cockpit size does not vary much - since there are controls and switches that have to be within easy reach of both pilots, both pilots seats are as close to the center console as possible. The distance that your head is from the centerline would vary only inches from even the smallest planes to the largest
You realize that the pilots of a widebody plane essentially still sit at the center of the plane, given that the pilot and co-pilot are only one arms length form one another?
