All 737 variants have shorter fuselages than the 757 variants. The 737 wingspan also differs between different generations, ranging from 28m for the Original and around 36m for the NG and MAX generations, but always less than the 757. The 737 fuselage width has remained constant throughout at 3.8m, similar to the 757.
While the 737-700 has a maximum payload of 42,000 lb (19,000 kg), the 737-800, after conversion, will be able to carry a payload of 50,000 lb (22,680 kg). This enables the -800BCF to carry 19% more payload, and because of the larger fuselage, the aircraft will have 40% more load space than its smaller variant.
