The maximum take-off weight of a Boeing 747-400 is 875,000 lbs
The 747 is much larger than the 787. The 747-400's maximum takeoff weight is 875,000 pounds. The 787- 800's maximum takeoff weight is 484,000 pounds.
The maximum take off weight for a 747-400 is 875,000 pounds or 396,890 kilos.
The Boeing 747-8 has a maximum takeoff weight (MTOW) of approximately 987,000 pounds (447,700 kilograms). Its empty weight is around 735,000 pounds (333,400 kilograms). This aircraft is the largest and newest variant of the Boeing 747 family, designed for long-haul flights.
The maximum gross takeoff weight of a 747-400 is approximately 900,000 pounds (408,233 kg). The empty weight is approximately 600,000 pounds (272,155 kg).
The Boeing 777's weight varies depending on the specific model. Generally, its maximum takeoff weight ranges from approximately 545,000 pounds for the 777-200 to around 775,000 pounds for the 777-300ER. The aircraft's empty weight typically falls between 300,000 and 400,000 pounds.
The weight of a Boeing 707 varies depending on the specific model and configuration. Generally, its maximum takeoff weight ranges from approximately 130,000 to 300,000 pounds (59,000 to 136,000 kilograms), with the most common models like the 707-320 having a maximum takeoff weight of around 295,000 pounds (134,000 kilograms).

The weight of a Boeing 777 varies depending on the specific model and configuration. For example, the Boeing 777-200 has a maximum takeoff weight (MTOW) of around 775,000 pounds (351,534 kg), while the Boeing 777-300 can have an MTOW of approximately 775,000 pounds as well. The Boeing 777-200LR and 777-300ER models have similar MTOW figures, but their operational weights may differ based on passenger and cargo loads.
The Boeing 777-200 is 247,200kg at the maximum takeoff weight while an empty one is 134,800kg.
The Boeing 737 is categorized as a Large Aircraft. The next category up is called a Heavy Aircraft and that category starts at 300,000 pounds (maximum certificated gross takeoff weight). A special "Heavy" category starting around 255,000 pounds was created for the Boeing 757 due to it's propensity to generate wake turbulence.
