# Is there a limit to how large an airplane wing can be? [duplicate]

There are some agreeably large planes out there, like the C-5 Super Galaxy. But how big can these planes' wings really get?

The heavier the plane, it is usually larger, and with size of the fuselage comes size in the wings (most of the time). But is there a limit to how big you can make your wings?

If you make your wings so big that they're 6 feet thick and an absurd length long, say, for a colossal plane, will those wings provide enough lift? I mean, if the wing gets that big, It not only has to lift the plane, but its own weight then becomes a concern. But, with that weight comes the size. Another issue, is how the aerodynamics work on such a crazy big plane.

The thicker the wing, the more air is contacting the wing. This causes more resistance on the wing at a given chunk than a smaller wing. The question comes from seeing several shows that depict planes so large they're like flying cities, and it just doesn't look realistic to me, the sheer size of those planes.

• No, my question is actually concerning the wing size, if the wings will work the same at such a size in comparison to the general smaller wings. But thanks for trying to help clear things up! May 20, 2021 at 17:50
• The big flying boats had wings a guy could walk through. Assuming that wasn't the tallest guy, the wing would still need to be about 5-6 feet thick at the thickest part. And they flew and flew well. May 20, 2021 at 18:11
• If the wing grows large enough relative to the other parts, you end up with a flying wing airplane. At the latest, then your question becomes a dupe. May 21, 2021 at 2:25
