Mewing, as previously said, will not modify the size of your nose; it will not make it larger, nor will it make it appear larger. Because the nose is mostly composed of cartilage and bone, the process of mewing has little effect on the size of the nose. However, what mewing does is change the shape of the face by removing excess fat from specific areas. The resulting shape is called a "mewed" face. As you can see, being overweight affects how your face looks, not just your body.
