Tristar outside fuselage width is well known. 597 cm. DC-10 is 5 cm wider, at 602 cm.
However, the Tristar walls are thinner at sides. The frames are thinner, skin is thicker and there are no stringers. Although Tristar is 5 cm narrower than DC-10 outside, the cabin is 5 cm wider due to thinner sidewalls.
Look at DC-10

10 seats, 2 aisles and their armrests combined have 224 inches width.
Tristar has 226 inches inside width.
Il-86 and Il-96 are 608 cm outside, 6 cm wider than DC-10. How do their sidewall thicknesses and cabin widths compare to Tristar and DC-10?
How wide is A350? I have heard different numbers, like 591 cm and 596 cm. Which is right, and how does the cabin compare against Tristar and DC-10?
